Thank you very much for answering me, that is what i need, much appreciated! 1. I crop, and i don't mind at all to crop, in fact most of what i imaged with one setup i crop, doesn't matter if it was from smaller sensor 4/3" or APS-C or even if i will use a full frame which i can crop a lot, cropping isn't a big deal for me, so that i want 400-450mm so i can crop and still have good nebulosity there, and i will crop only the overlap that is not huge if all rigs systems are very similar in FOV, if you go to previous pages i think i posted 3 images i did before as tests, all are cropped and i am happy with that. 2. Not with 2 90s as i still keep the second 90 inside the shipping box and never opened yet, i did this with my two 60mm doublets and two 4/3" cameras, both scopes are same design but different brands, also with two cameras, same specs but different brands, and it matched or worked seamlessly together, so i assume if i use same exact setup it should work, i mean no reason why it work with two rigs and not with other two the same, maybe 90 could be complicated a bit, but i will manage. 3. Yes, not enough mono NB data, and i always hate stars from NB filters, so i decided i will force myself using only RGB starts, with this it means it is impossible i finish one target doing NB and RGB in one night or even 2 nights, and i hate to spend so so many nights for one target, so i can give maximum 2 nights per target, and in my area most targets aren't staying longer than 3-4 hours at best altitude in sky, so i am almost forced to 3 hours maximum at best, or less, so means hours of data translated into so many nights, i want to cut that by having many data per night, if i needed little more i just complete it next night possible only, so if i use say 3 rigs and each is capturing at least 2 hours this means 6 hours per night, one rig it means like 2-3 nights, so in 2 nights i can manage about 12 hours, at the long run if i can have enough targets then later i could add like 2-3 nights more on my old targets, but i won't spend full year only completing 4-6 targets. 4. Same targets with those 3-4 scopes not different, OSC i planned to use it only for RGB stars, but i did like a mistake that forcing me to use OSC again, which is having a dual band filter, L-Ultimate, the Ha/OIII 3nm 2" filter, so i need like two OSC then, one for RGB alone and one for dual band filter, the other mono will be for SII/Lum, maybe i add like Ha or OIII alone to have better signal from mono and add it to OSC dual band, many ways i can think about, in all cases i will always use a mono in my setup, and if RGB is working nice for RGB stars then fine, i tried it twice, it was bad because i used LP filter that killed it a bit, i got stars just fine, only colors a bit off, i think without that LP i could have nice colors stars then but i didn't try, i will have time soon to test again, just i have to be ready if OSC gave me nice results then i should include it, and NB is much easier than broadband under LP skies anyway. 5. All of them when possible, but i can say it will be like 90% nebulae, and the rest for clusters and galaxies as those are a bit difficult from LP, but can be done, and i need lots and lots and lots of data for integration time, hence i wanted many imaging system to capture more at less time, fast optics isn't in my plan yet, but that will be far future plan maybe. 6. I tried several targets with only one setup and mono, i could never have enough data in short time, Ha alone eating full night and even i need more, most of the time i just go with like 2 hrs Ha nd 1 hr OIII and 1 hr SII in 1-2 nights and accept it it is done and i don't add more later, ha is standing out just ok not perfect, while OIII and SII are weak, so i will never go out every night just to add data of one target, i always keep thinking why i only doing it with 1 setup and not 2 or 3 or more, i mean while i wait one setup to complete one filter only and yet not enough i could start another one for another data, that was my plan, i used one setup and i wasn't happy doing it, 3 years and i barely could have one target or two perfect enough even easy one, also i might decide to go to dark skies later in future so i think OSC can do the job as i won't go there often maybe only 1-2 times per year so i have to get enough data in one night as possible, i don't have RASA or Hyperstar and might never get one, but who knows. 7. I always have time for processing data when i am waking up in the morning or afternoon, or even at night while i am waiting my setup outside collecting photos, i don't work no job so i have time, i only get busy because of family or friends at night, so definitely there is time for that. By the way, the main cause of issues i have in the past was from my old laptop that it has Windows 7 yet never upgraded, and also with power and connection, it wasn't with camera and scope focus or filters really, so what wasted a lot of my time is that sudden disconnect of imaging camera or guiding camera or mount going weird and such, i bought mini PC only by end of 2022 so last year for tests it fixed my problems, and also my Pegasus Power Box managed my connections and powering, and i also decided to use a separate power to my mount, that solved most issues i had back, and while i was fixing those issues i just bought more stuff and items while fixing, so i just won't drop and sell them now after i got them at great prices, i need to use them properly when possible, i didn't share anything since maybe 2021-2022 of DSO, only solar last year and i won with one, also planetary without sharing, but this year i have to get back to DSO imaging after long break, two 90s and two 60s with FRA400 are all ready, also this year i am planning to buy an affordable mount for my other new scope which is RC 10" truss design, it will be used for galaxies and clusters, and sometimes nebulae but mainly Planetary nebulae, that is also i want to have another scope to match it which is another story and topic not bringing here. One step at time is true, i did that since 2017, but got bad situations between 2018 until 2021 which preventing me to do more of DSO imaging and setup management, so i was just shopping and collecting items which i want to use now and not dump them, and 2018-2019 were years of planetary for me and i was happy, many moon and planets images i had so i didn't focus on DSO, 2020 is COVID years, 2021 my wife's new location job, no need to continue more but i decided to stop 1-2 years then i can return, now is the time for that, i have helpers [Brother in law and my wife's cousin] to setup my equipment so that also minimizing a lot of my time.

I think i was clear in my posts, i already have two IMX571 cameras, it is not from ZWO or QHY, it is from ToupTek, same sensor in 2600 cameras, so both the mono and OSC will be used with my both two same exact scopes of TS Optics 90mm f/6 CF APO triplet, so i have two identical same setup exactly just one with mono and one with color camera, and i bought new scope which is 106 f/6.6, i was thinking about getting 0.6x reducer to make it wide to 420mm which is very close to two 90s, and i want to use also another IMX571 sensor for that new scope so i can have same sensor of three rigs being one scope is different, then if i have enough budget i can add 4th rig be it my 300mm lens with 1.4x or whatever else to have FL of about 400-430mm then i also think about 4th IMX571 camera, i bought both cameras at very nice prices, i can add 3rd as color not a problem, but if i have to add two more mono then that will cost me a bit and i can only have one mono now and wait longer for last one, and it will force me to buy one more filter as OIII because i have Ha and SII 3nm 2" filters already, but i also have dual band filter of L-Ultimate which is Ha/OIII 3nm, so i was thinking if this is gonna be practical enough wit OSC then should i buy another OSC as i want to use one OSC i have for RGB stars only, or i am forced to buy RGB filters which means another budget to be spent, so i asked to plan wisely, i already have extra scopes and lenses, i want to use them all or most more as like 3-4 together than use only 1 or 2 for several nights to complete 1 target at least.

I am shopping for autofocuser for all my scopes as much i can, i have one for one 90 CF APO for now and will buy another one the same exactly for the second 90, and last month or November i received ZWO EAF so it will be used with Askar FRA400, then i will be left with 106 and two 60s doublets and RC and Newt. I always take flat frames even if i keep my camera/scope on the mount for next night, because i know any movement and i could present dust movement too, or even new dust coming for another night, it is very easy to take flats, only if it is good enough to be used, to be honest i never had issues with flats for narrowbanding, while for broadbanding it is not working for me, so i will try to fix this issue sooner or later, and about rotators, well, that will definitely cost a lot, i understand automating things will make the mission easier a bit, but i can't tell how far i can automate things with my setup, most likely rotation isn't gonna happen any soon for automation and i will just go with manual rotation, but some people told me that software can manage align frames even with different rotations, so i will depend on processing to correct and fix most non automated devices..

Actually i started this to ask about which two cameras, let's say one camera for now, you pushed it into the topic of the useless or issues of dual/multiple rigs, and i tried to explain my situations or reasons as much i can, and now i forgot about the main question about which camera, but yes, i will always start with two first to match perfectly as i can, when that is going great for a while then i can add more, and still the question is waiting the answer, when i add third or 4th rigs, which cameras then, i have IMX571 one mono and one OSC now, so need to decide if i add same sensor again 1-2 of them, which version. Thank you.

When i did dual imaging before i rotated one camera to match the other one roughly as much i can so they are both almost in same or very similar orientation, i didn't forget that, i even try to make both targets in the frame like almost 98% matching even most of the stars by edges so i know i will not crop so much between the two, and i will learn about plate solving also so it can help me centering both frames so i don't have big shifts between both, in fact i always crop a single rig results to make the main nebula like standing out, as i didn't like stars by the edges even after calibration and didn't have that BXT in the past, not a big deal for me cropped dual rigs frames, i always take test shots/frame before i start the real imaging, if the exposure and the framing are all good then i start imaging.

That is why i am focusing to have multiple rigs at range of 400-435mm at best i can, so i can crop just fine and still the nebula in the frame is enough, i post an example here for Orion, i have another rigs for much wider, but i like this 400-450mm range from 80-100mm aperture scopes, the example are just two scopes of 90mm f/6 + 0.8x vs. 106mm f/6.6 + 0.6x, both using IMX571 sensor cameras, i didn't add FRA400 there or the lens 300mm f/2.8 + 1.4x.

I haven't experienced HD mounts, i will give a look at it and see what they are, thank you

Not 4 different scopes, but say two are the same which are the 2 TS CF 90s, then adding one different which is my new 106 reducer to 420mm so a bi wider than 90 reduced, and last one is a lens Canon 300mm f2.8 adding 1.4x TC i can reach to 420mm, it is actually a 107mm lens but so fast which is same to 106mm aperture i believe, so it is like 2+1+1, i was thinking about FOV more than aperture size or FL, and i crop the wider frame to have smaller common between the two, so that is also not possible, or instead of the lens i can use my FRA400 native, and using something like 294 sensor to almost matching that 2 90 scopes FOV maybe, i will use the two 90s as the main one, just want to know if adding at least one more scope a bit different but close isn't working.

What is aligning? How is that a problem with different rigs? I saw many collaborations on the net where they used so different rigs maybe up to 8-10 rigs and they managed to have that unique results, i don't know about the processing time they spent, but if it is possible then what is the problem then or where will be the problem of aligning?

Three is also the maximum i will try to have, i won't go out placing 4-6 different rigs to cut it out, but i will try to focus with two or three at most, i think it is enough for long term, then i can add more or even reduce it back to one according to situations i am at, but i can't just decide that if Person A failed with 2 rigs and Person B also failed with 3 rigs then i will fail also with 2/3 rigs, i have items that others aren't happy with and i am happy with and managed to make it works for me nicely, so i know what i am facing and then i have to accept it, i used to carry my AZ-EQ6 mount with tripod and head together and that was killing me for nearly 4 years and i never tried to buy a portable mount, and dissembling/assembling it is even worse than carrying it in/out all the time, so that is the reason i stopped to buy more.

Nice post from you, thank you Well, i didn't enjoy with one setup anyway, and even after i manage to make it as perfect as it can be then it is again short time collecting, and because i don't have any obsy and maybe will never have one then i have to find another way even if it is a bit headache, it is all about the data collected, and not the ease of setup to make, because i know no matter how easy i can manage the setup, one way or another after a while i will feel frustrated to go out many nights to complete very few targets, and back then getting a very fast setup wasn't the option, and with buying more cameras or scopes it is not going back in time now to get fast. i know the cost is like more, but it is what it is with me, i can spend like $3000 in say 2 years or 16 months instead of one time direct, so i continue what i started rather than start again in different path. I will say that if i will have like extra rigs to setup then i can manage to have each done properly, i know the more data and quality of it is what will make the difference, i saw many have one setup done properly and still data isn't that good and also they spent nights over nights to collect data, i did that for like 3 years and i wasn't happy, so i wanted to find a way to accelerate things, and driving to dark skies isn't an option for me, so it came the plan of multiple setup, and i mentioned or maybe not that i saw people who did this multiple successfully even after little efforts and nightmares, but it works and they are happy, and i saw lots and lots of collaborations on AB with people around the world different locations with different setup maybe resulting into like hundreds hours of integration and it is APOD/IOTD like, so it can be done, it is just people keep saying we aren't into multiple setup because it makes us more tired and more nightmare to see, yes, i agree, but i already have that nightmare with one setup and i have my own decision to maximize that and then i maximize the data collected too, and that is all what matter, i tried it once and it worked nicely for me without much headache really because i know how to setup now after years of experience and frustration, then i stopped as i want to add more and just do the same with dual rigs i did, if others still have issues with two/dual rigs no matter what it is their own fault, if i never faced those issues in the past i believe i will keep facing them with many rigs too, and i went slowly to solve each issue so i know where is the issue coming from in my setup.

I did use F2 lens before at F2 [my Canon 135mm F2], and to surprise you, i needed like 3 nights to do Orion M42, one night only Ha, another night RG as i couldn't complete B due to weather, and last night i did B and Lum, i got enough signals but i had bad CA with blue halo, used a mono camera, so the lens wasn't corrected much, and doing it in 3 nights kind of defying the point being a fast optics then, i mean good i faced bad weather in the middle of RGB imaging, that is why i said i wanted to have multiple scopes and cameras, changing filters and managing focus is also important, so if i will have RASA then cabling is a nightmare mainly for dew, also collimating RASA if so isn't friendly thing, i did read cons of RASA by others, and i found out that i prefer the cons of refractors more than RASA or SCT and alike. I didn't mention that i also have Newt, not fast but i can use that Starizona reducer for F4 Newt and i will be at F3, it is fast enough, faster than F5 or F6 or even F4.5, that will be in use for something else, also i have Canon EF lens 300mm f2.8, i was happy collecting data with it at speed really, just stars were so bad, and i wanted to spend full night collecting one data of Ha rather than doing 1hr Ha 1hr OIII and 1hr SII ad call it a night, but if i will put it in use then i should just buy FRA300 to match its focal length, so EF 300 for NB and FRA300 for RGB, two will be sufficient, i even can add FRA400 with 0.7x reducer to be at 280mm, but for now i am trying to stick to 420-432mm one then i do other scopes and lens i have when necessary.

If the price is correct then i have to say that i wasn't able to afford that in short time before, and when i bought my first 90mm APO i didn't have $2000 or more actually, in fact both 90s i managed to buy for about $3200 together [i bought separately], so nearly $1000 less than RASA 8, now i can think about RASA only if i will shoot for Ha/OIII/SII alone, because then i can capture RGB stars with my FRA400 and both are 400, i don't need to buy a fast speed light shift NB filters for this RASA and just use my current NB filters, will not sell my current scopes in favor of a RASA.

I saw his gallery before in the past, i don't know him, some of his images are from Bortle 9, and some are like from Bortle 1-3 for example one of his M45 is Bortle 1 or Andromeda, Saudi has more areas of darker skies than UAE, bigger country and kind of he is lucky to drive around rather than in my crowded country. I can't do that until i buy a second mount that is in same rating of my AZ-EQ6, i was thinking about something cheaper up to at least 10KG maybe which is sufficient for one 90 CF APO with accessories, i will miss the opportunity to buy a mount that is rated for 20KG and a bit expensive and it is a harmonic drive, the expensive i can afford late, the cheaper i can afford within 1-2 months at most, so difficult decision, mostly if i also want to afford that camera for my new scope, but i think that can wait then.

It is ok, your opinion is valuable, i will use one setup when i want to slow down or being calm not in rush, but the plan is there maybe since 2020 when i bought my second mono cooled camera.

Hi Phil, Well, i knew that you will post or say something like that, this is not the first time or you are first one to say that, i got that a lot, only because i stopped imaging and doing shopping for gear everyday or night, i understand, but that won't stop me from shopping anyway and also won't scare me from doing things. My main issues in the past was my lack of knowledge mainly, then lack of items, and then the items errors and problems itself, so by the time i was learning and understanding better i almost managed to do things right, i don't care about how many times nightmare i faced to setup nicely, it was that one time i did setup perfect without issues, in fact i never tried to spend so many nights to make setup just right working away, i was just doing things in hurry to test few things more, like testing guiding, testing new filter, testing new camera, for those testing i don't care to have perfect managed setup as i know i will tear it apart always to try other setup, so when i confirm that a filter is working even under meh not right setup i just go next testing another item and another and another, once i am ready then i can put it under perfect setup and start imaging. The problem is still applied, with bad or perfect managed setup, i can't do things in one night and done complete result, say i spend 2 hours before sunset to have my setup fully ready free of issues, for most targets by night i still have like like 2-4 hours [5hours at best by winter if the sky is clear], so i will keep going out every night to complete the set of data per target, believe me, it won't make me to keep going or continue as well, i came to this plan of multi imaging system for a purpose, once i complete the gear then i can setup them separately, i do have a helper now for as long it takes until he is no longer available or i decide to stop, i also still think about having a fixed observatory somewhere by my property, if that will happen someday in future then i am lucky enough that i hear equipment ready rather than wish if i bought more earlier, it is simple policy "Buy now, test/use later", with say 5 rigs i still can always use only one anyway, so with more i know i can setup when necessary, for me it is very easy really, setup one and let it start while working on the second one, for SHO i start first as it will collect more time, while for OSC or RGB it needs maybe about 1 hour minimum, so i can spend 1 hour for second rig of RGB, then it will collect data for like 1-3 hours, this way i have two rigs working, and if it is portable enough then i can carry around by myself, my AZ-EQ6 alone without setup without counterweight but assembled with tripod is always bloody heavy, that only stopped me from going out imaging. With AZ-GTi for just tests, i used it from my daughter's bedroom window for solar only, i tested mt new CaK tool and i won IOTD in one known solar site, that is alone made me to feel i am doing or going right, and it wasn't polar aligned or guiding not even tracking, just manual, and my daughter window is facing South perfectly opposite to my window which is facing North, but my view is right into LED streetlights, while my daughter direction is no LED, only maybe from few houses not strong direct light and far away street light but the sky is almost ok away from LP, so i can try south direction targets from there even for short exposures, last 2 years and also 2020 i wasn't in mood and tough busy, 2021 was almost ok but i was like in the beginning and middle of buying nicer gear such as my first APO scopes and more cooled cameras and filters, so before 2020-2021 i only had ST80 as refractor and bad laptop full of issues and not great filters except Astrodon Ha only and average other filters and one mono cooled camera, so i was doing planetary in 2018-half 2020, shopping made me lazy so i decided i will keep shopping and testing only, now 3 years enough shopping i am like at the end of my purchases, only adding last batch and i am done, i don't think i will buy 10 cooled cameras like i did with scopes, for me if i can afford say 4 mono cameras of same model then i can use this for all scopes and lenses i have as i won't use 8-15 scopes all at once per night, most likely it is 2 as minimum and maybe 4 as maximum [5 if i might include a lens and small mount]. Your advice and point has been taken and considered, thank you

I have the saddle for that, actually i have like three different aligning saddle so i can manage to have two or more scopes pointing at same target together, i did it before, and then i can use like NINA to have separate acquisition or just open two different software for that, i can do that with two exact same scopes rather than two different with so close FOV, whatever is working anyway, but with more mounts this will be much easier, i can setup each rig separately easy as long i will have say different PC/remote program and power box, kind of i need to go around with software and hardware to make it work, i do have an old laptop i gave up using it and new mini pc and also two Raspberry Pi 4, might buy RPi 5 and another small cheap mini PC while waiting to buy that new mount, then will see what else i can add. I was thinking to use my FRA400 native with OSC so this will be the wider FOV for stars, and the scope is a Quintuplet, so corrected for both CA and field curvature, this way i never worry about stars shape and colors, while two 90s can collect say SHO, then i have to decide what i can use 106 reduced for, Ha alone maybe, or lum, or if using another OSC then dual band for Ha/OIII then one 90 for SII and second for maybe lum or OIII to have stronger signal for that beside Ha, i can think of many ways depends if i will buy two more mono or just one mono and one OSC which i asked about initially.

If i have those exact 4 scopes then yes, but definitely now 😂

I will come to that later, i really didn't test my DSO setup after this LED lights on since 2022, i will see how things are changed now, worse or just normal. That is exactly the problem with D2 filter, my cluster ended up to have say yellow and green colors of stars, couldn't see blue or red here, it cuts off a lot in both ends, so that i don't use it anymore, but i could try using it as lum with mono if it will cut a lot of LP anyway, and for RGB stars i will just use UV/IR cut [Lum] filter.

I saw people used even up to 80mm aperture scope with this mount, so i have to see what is the limits, with this mount i know i can use my 60 doublet just fine, not sure about FRA400 as it is a bit heavy, i bought 30mm guide scopes for that, i do have QHY mini guide scope with QHY5II-L-M camera and the setup is like feather light, nothing, i even feel it doesn't reach 1kg even, and i will try not use any filter wheel, so i will give it a try, i believe 90 triplet is definitely a no, then i just wait to buy another mount a harmonic cheaper one i found that is rated up to 20KG with counterweights, if i can really mount 2 scopes together and learn about dithering and aligning then it is a big help, i do have some accessories for that, so will see how it will be later.

Those are nice beautiful images, i like them. Yes, i know that it is possible to do broadbanding images from LP skies, it just needs lots of frames for longest integration time possible, and that is why i am doing this multiple imaging rigs to cut down the time capturing, it is very simple, if i need say 12 hours when one night is only maximum 4 hours it means 3 nights, if i have 3 rigs each capturing 4 hours of data with different filters or even same data i will have 12 hours in one night, imaging if i need to capture like 10 targets at least and each is 12 hours minimum, this is 120 hours, i am not good in calculations, but if i do it with one rig so 120 hours is equal 30 nights with each night as 4 hours, this is like imaging for full month every night or half month within two months, i never had one month with full clear sky, must have something even one night, so with three rigs it is just 10 nights, i will try to make those rigs as fixed as possible to i don't have headache of setup every time. After testing my IDAS D2 filter i gave up to use any LP filter with a color camera, i mean that D2 wasn't cheap anyway, if i can sell it then i might think of another LP filter, maybe i should use this D2 with my mono camera as lum because it is more suppression than regular lum filter, so maybe less gradients to deal with, i tested most targets back in time before they install LED lights but still light polluted sky, and i was able to capture most signals of targets be it a nebula or galaxy or a cluster, but since LED is operated i didn't try again, i can't remember that M5/M13 ones i did was before LED on or after, need to check out the time and date, and once i also tried a galaxy with only lum filter, the galaxy was so clear in the frame but full of donuts rings that i couldn't correct with flat frames.

Hi Carole, Nice to see you again. Well, i know how bad is that broadband under bad LP skies, but i tried it twice or say i tried it for two clusters and it wasn't completely bad really, i will post an image of what I've got later to show you all, it is just i have to be careful of what i choose as extra, i mean i am sure i will add second mono of this APS-C size, but then for4th camera i am not sure if it should be also a mono to have 3 total or second OSC for dual/triad/quad band filters, things are getting nicer by the time, and i feel like people are using more of OSC cameras now even under bad conditions because technology has improved, and those new sensors all are happy with so far me too, so if someone suggest to add another OSC then i can buy this before i afford second mono, if not ad only two more mono then i will just save for second mono now and wait longer time to afford the third one, i think i want to keep one OSC anyway, i also have another scopes that can do nice with OSC such as my RC for distant targets even under light pollution. If i will use my small refractors such as my 60mm doublets or 72 then i do have two small portable mounts, so i can have like two rigs separately, i also have AZ-EQ6 which i can mount another two to mid rigs together on it, until i buy one more mount portable better than the one i have then i can have option with 4 mounts, just i have to check out if the mount AZ-GTi can't handle 90mm triplet with few accessories then it will be easy, i am doing this for nebulae where i need to do a lot of SHO or HOO so i keep RGB separate, i never like stars from SHO data, so RGB for me now is like a must addition, while for galaxies and clusters i will have RGB as main data anyway, then add anything else such as lum or Ha if necessary. Tareq

Thank you very much, Pierre! I might go back to some of my old pictures and process them different and further with new tools out there, i just focus on having better setup and newer and better data if possible, i can redo them all again if necessary or just collect more data to add to old one, i just don't want to have worse results mixing meh with good, but who knows, i still saved my old pics just in case. I think the filter i was using isn't the best to be used, the result wasn't good, but i am sure some will say it is really nice, the idea is that i bought it because they mentioned it is good enough with OSC under light pollution with LED, in fact it killed most of the blue, and i think i sacrificed a color for having something less LP, wasn't a good idea, i should just use UV/IR cut filter for my OSC and collect more data that's all, will give it a try next time on something away further than LP dome. The idea with OSC is stars, i mean i saw many taking like short time exposures for RGB stars to add to LSHO data, so i was thinking if i will use OSC for really long time then i should have nice data of RGB of stars, i bought mono for narrowbanding anyway, now i asked my question and started this thread for the extra cameras, i mean i already have one OSC for RGB stars, one mono say for Ha for example or SII, now if i will add third and forth should i also have more mono? I was thinking like another OSC for only dual band Ha/OIII and one mono for SII to have that SHO, but someone voted for 3 mono for SHO and one OSC for RGB, setup isn't a headache as i already suffered in the past so i fixed most issues of setup and i know what i am doing or to setup quickly in my yard, i have a helper.

I once tested the color camera for clusters [M5 and M13 i believe], both were bad, simply because the filter i was using as LP filter is killing too much, i mean it was like i shoot with 2 colors only instead of all, had long time to process it good enough and still not satisfied, so i think without the filter it could be better, it only shows that OSC is capable if done properly, i bought it cheaper than competitors, so i forced myself to use it, i judged it regardless it is a broadband result under heavy LP so what i should expect, never tested with a dual NB filter to see, that might be different, but someone just mentioned to me about that color sensor with half green and 1/4 red and blue will never make it good for anything even NB, was thinking about it, but results from people over the world saying otherwise. The idea is that maybe one day i can add another mount that is portable enough so i can travel to darker skies even not that much dark but better than LP areas, then OSC can be a big savor in this case, i have one for RGB already, maybe another one with dual band filter can also save me two filters at once, some targets are nice enough as HOORGB already such as Veil and Crescent in Cygnus.

The new scope is already here, i can use it as separate alone different scope, or as additional be it as main or backup to what i have but need to use a reducer to match, so sooner or later i have to buy another camera for it rather than i swap a camera from one scope to another, my two 90mm triplets will be better to be connected with cameras after i calculated the back focus and leave it there, it is also headache to keep moving the camera and whatever filters from one scope to another, i will have to do that anyway with many scopes i have, so i try to fix one FOV setup then adding more to that, my 90mm with 0.8x reducer giving nice FL of 432mm to most targets, and with APS-C sensor it is even nicer, so i try now to match my new 106mm to that, i came with 0.75x reducer, but i will buy 0.6x reducer to give me 420mm, with APS-C it is similar close to 432mm with same sensor, if i can use my 300mm 2.8 lens with 1.4x that also will give me 420mm, so i can have two scopes at 432mm and one scope and a lens at 420mm, i want to use same camera sensor with all, i already have two IMX571 one mono and one OSC, for this 106+reducer i have to think about either a mono with Ha or OSC with L-Ultimate, then i have to decide what i can use that 300+1.4x with and for.
