    After a few months hiatus, weather, work and holiday, I finally got back into imaging mode last Sunday night into early hours - it was a cracking night for astronomy ,cold, clear and dry. I am still using my Samyang 135mm paired with ASI1600MC - its a compelling combination as it is a very light combo and the camera sensitivity allows me to use my AZ-EQ6 mount unguided with 30s or 60s subs. So I took 60 x 60s subs in Ha(7nm), Baader, I used my flat,dark and bias from last session as nothing had changed in the setup (its in a obsy) and DSS stacked 54 of them This is 54minutes capture with curves and levels stretch in PS and also used a mild process with AstroFlat , probably a bit noisy but given the short integration time, its not too bad. Anyone have any pointers how to best process Ha, I will admit not having tried too hard to find any specific tutorials yet as I was quite pleased with the light processing I applied. I also captured two exposure sets of Lum 30s and 15s (1.5hr worth) plus 30min Red, but Orion was obscured behind my hedge by 3am so next session I can capture Green and Blue then I can compose a HaLRGB image. (The hedge got a 'trim' yesterday ) Thanks for looking, Bryan I

    Finally managed to get started with my imaging againg. This is the first image of the season for me. 57*5 minutes on the Cocoon Nebula using my modded EOS 550D and Skywatcher 150-PDS. Now for the season is my garden pier. Seems stable enough Tried to keep the editing on the shy side to keep a more subtle look than what I could have done.

    Smashing night last night ey? No moon, and a perfect sky - just right for grabbing OIII. So I managed to get in three 2hr panels - enough to put colour into the image. And for a change I've gone for a bit of star colour as well being as it is not a cannistra process image (though I might try one of those later this week). Ideally, I'd like to take the Ha luminance up to 8 hours per panel in order to beat down the noise a bit more for the pixel peepers - but for now 6 hours per panel in Ha will be enough to get the general gist of what the image is about. Tons of layer masks went into this in order to keep the bubble under control, as well as layering in a bubble from the 130pds - which sharpened it up really nicely. The colour has turned out alright too (for a change!). 24x900 (Ha_L), 8x900 (Ha_R), 8x900 (OIII B&G) x panels Star 71, NEQ6, Atik 383L+ Thanks for looking!

    I set off well wrapped up wondering if this would be my last session without a building to warm up in until late March. I had planned well and was ready on a clear and crisp evening. Firstly, I wanted to see if I could see M30 in Capricorn for the first time. It's pretty low and it would be my last chance before next Autumn. Unfortunately the sky was too bright down there so it was a no go. Then to the Trapezium galaxy- M33. I was pretty confident and tried first with binoculars (unsuccessfully) and then with the scope (unsuccessfully). Some clouds started moving about so I moved to Aries to Kullat Nunu in Pisces looking for M74. This time I was sure I had the exact place but no galaxy. Then down to look for Uranus (all these targets were/are new to me). Anyway, I wasn't sure if I had kicked off from the right star and Uranus, if I did see it, was definitely disguised as a star. As some more clouds covered that area I went to Cygnus to look for M29 the Cooling Tower but it was impossible at this point to tell what was a cluster and what was the Milky Way. Then to M57 the ring nebula-the best I'd ever seen it- for about thirty seconds until it was covered by clouds. Then I had a snack and some warming tea as the clouds rolled over the whole sky. They showed no sign of clearing so I packed up and walked home and when I reached the door, I looked up and saw stars again. Anyway, now I'm home and warm and happy. I actually had a pretty enjoyable evening. There's something magical about sitting outside with a flask of tea. Thanks for reading.

    Hi again! Last time I imaged IC5070 for approx 3 hours, then as Orion rose up I decide to use up the last of the clear skies imaging B33/NGC2024. 15 x 600s at ISO1600 with Canon 1000d, ED80 FFx0.85, darks and bias. Looking any advise on detail etc, how does guiding look, focus, etc. I'd like to try to progress so feedback welcome. It is still noisy, so definitely need more subs. I've also lost the plot somewhere with it somewhere during processing as there is artefacts all over the show! Thanks in advance Adam.

    I went out on Monday morning with the intention of capturing the Venus / Jupiter conjunction ; just a simple prime focus image with the DSLR. As they were less than a third of a degree apart, they would sit nicely in my refractor. I went out early at 06:45, but had forgotten the clocks had gone back a couple of weeks ago : it was no longer dark and morning twilight was rapidly advancing. So i quickly set the mount up, and went into my shed to get my refractor. Uh-oh...its not there. Doh, i realised i'd left it in my garage overnight after making a few adjustments. In my 20 deg heated garage....!! The view of the 2 planets looked like 2 'Wifi' signals you get on your phone standing side by side !! Thermal equilibrium....no chance. I put the scope away and settled for a 135mm lens instead. But i saw the conjuncion anyway, it was a beautiful, clear morning, and Venus and Jupiter looked a treat.

    I got hooked on clusters last full moon and found this. A double cluster to rival the Perseo example. In anticipation of galaxy season and so as to get practise at long focal lengths I did 2 shots; 750mm-f5 and 1200mm-f8. A lot of the smaller clusters are tiny at short focal lengths. As usual, the colour sent me crazy. I think in this case, I'm missing blue. All comments most welcome. 700d: 20x120s and 20x180s

    The sky cleared right up tonight and a nice relaxing sky cruise was had, no difficult targets were chosen. Sometimes looking at the same object(s) over and over helps certain features stand out and tonight a really nice star cluster, NGC 6997 grabbed my attention every time the 15" dob was swung on the North American nebula. The UHC gave a fantastic view of this cluster buried in the grey glow of the nebula riveting my attention. Thinking things were pretty good sky wise I popped up to the Scorpion and one of the Claws was contrasted nicely and the Bubble nebula was "bright" with a bit of small subtle structure. Pickerings Wisp released its twisted structure tonight along with that dark hole in the middle of the triangle- the 20mm Lunt HDC/Lumicon OIII work very well together on these objects. For some reason though I was going back to the NAN and its nice set of stars in that cluster...strange, I've seen it so many times. The UHC did a great job tonight showing many stars and the nebulae. A quick blast over the Stephans Quintet satisfied my curiosity as to if it was still there-its still there

    This year has been the most fun I've had stargazing (only been 4 years mind!). Joining a local astro club, meeting more experienced observers and enjoying some really dark skies have shown me a whole new side to the hobby. My first scope was a Celestron 6se and although I did have some decent times with it, I found the goto a bit challenging to get working well. So I moved onto alt az slo mo mounts such as the porta 2 with the relatively small tv85 and Tak fc100df. I got on better with these and began to learn the skies and be able to star hop to new objects reasonably easy. Then last year I purchased a larger refractor and mounted this on a rock solid t-Rex mount with slo mo. This worked well but I still found star hopping a challenge in the light polluted sw London skies. In addition, although the slo mo controls were smooth, the constant twiddling of the controls did impact my ability to concentrate on the target. So a few months ago, the skywatcher az gti mount was released and I found it a revelation with 100mm tak. The set up was really easy (I think my experience gained does help me compared to a few years ago - and also sky safari...). But maybe the best bit was the automatic tracking which allowed me to just relax and enjoy the target object for much longer periods. I think my most fun nights (astronomy wise ?) were in August under a dark warm sky with the az gti and my tak drinking in some lovely objects such as the veil, double double, blue snowball and Caroline's rose. However, at times, I did find myself wanting that bit more aperture which the az gti couldn't do. So I looked around for a mount that was quick and easy to set up, could hold a large retractor, had goto and was not too heavy to move/transport around. I was struggling until I came around a recent astronomy now magazine which reviewed a Danish mount called the TTS-160 panther. I placed an order and it arrived today and so far it looks pretty good to me. I've set it up indoors and it's straightforward and quick. My 130mm looks overmounted! Heres a photo showing the mount in its transport bags with the t-Rex mount behind it. Ihave a couple of extra bags for a pier extension and a heavier set of weights but in normal use I think I won't need them. Also there is a photo of the mount set up with my 130mm refractor sitting atop it. Finally to complete my new visual set up, I am awaiting a new scope which has been on order since June. I've been told it will be shipped from overseas this week so I looking forward to trying out my complete new set up soon.

    Probably not the best target for my unmodded 550D and with half the moon lit up, but i wanted to give it a go anyway. Image is 42x 600s exposures at ISO 800 with the Explorer 200. Stacked in DSS and processed in PS. I used the CLS filter when imaging this and it helped a lot on the light pollution from the nearby city, but it did affect the star color quite a bit. 7 hours of exposure did help a bit bringing out the nebula and i'm quite happy with it. It's still a bit noisy and not very deep though, but i'm sure i'll get back to it at a later point with a better/modded camera and no moon...

    Have now added 3 hours of OIII from last night to my 5 hours of Ha, all 20 min subs, ISO800. Equipment as per my signature block. I am not finished with this yet, but could not resist posting it to get opinions on it as a work in progress. Not sure my pallet is very conventional but I like it, hopefully not pushed it too far as I often tend to do. This was my first time imaging this target and I was a little shocked by how faint the OIII signal was. Edit: So I got my flats working and toned the whole thing down a little. Also decided I like it better standing upright. I should learn my lesson I always rush to post to early...... Adam

    Yep, that's exactly my experience too. I have 4,5,6,7,8,9,10mm for planets. For other targets I'm happy with 70% jumps but tweaking the image on planets is a very different matter. Though of course since the planets are now on holiday in Australia for the foreseeable future, it's all somehwat moot

    hi guys and gals OK finally starting to figure out how to use all this new software and hardware for viewing and imaging the sun finally a first decent image of a prominence today 2017/11/14 gear - Lunt LS60THa solar telescope, ZWO178MC camera and SharpCap software trying to image in daytime is a real challenge ... dealing with daytime glare on a laptop screen etc this is a single image capture the basic setup just a quick pic of the setup laptop inside cardboard box for some shielding of the screen from the sunlight. I needed to stick my head into the box up close to the screen to stop the sunlight reflections off me getting onto the screen .... regards Dave

    I can't believe that it is over 12 months that i was given the go-ahead to sort out a observatory\shed for my nocturnal activity, where does the time go Anyway i have finally made a start, not the best time of year for doing it i know but hey ho! I did have a 9x7 shed already in the garden, that however has now gone,upon close examination it really was not suitable, This does mean though that all my equipment is currently in storage, My pier is already concreted in place so i am having to work around this for siting new observatory\shed, I did get some quotes for having the ground work done but they were coming in at around £500 mark, hence why i'm doing it myself (cheapskate) Cost to me to get ground work done,£207.40 + my time.(that to me is £300 towards observatory\shed) wacker plate hire £29.40 (weekend hire) 1 ton gravel £50 + (£30 delivery),unless anyone knows anywhere cheaper, 10x8 Ecodeck £98 free delivery. there was a small area that had uneven concrete that rain water seemed to pool in, so that had to go,(back breaking work and i am so glad it was only a small area) but i think that is going to be most of the hard work out of the way, My next step is to get the area 10x8 around the pier level, My plan for this is to level ground as best i can then put down probably 10mm or 20mm gravel, run a wacker plate over that to get nice and compact,should also help with drainage, Once that is done i then plan on putting down a weed membrane then place some of this Ecodeck plastic shed base then fill this with gravel which hopefully will then give me a nice solid level base for the observatory\shed to sit on, At the moment i cannot make my mind up whether to go with wood or plastic? if wood (reasonable cost) it will be 8x7 which will allow access all round for maintenence\treating if plastic (slightly more expensive) i could go to 8x8 as this should really be maintence free (hopefully) so at the moment it is ground work in progress updates to follow

    Not quite a review - yet - but more of a just-after-unboxing session. Having ordered a Borg 71FL from our friends at FLO, I was gleefully contemplating using it in tandem with my TV-60. Having passed on both the Ercole and the Ercole Mini, both having honorably served but having been superseded by the Losmandy AZ8, I was left with the AZ8 as the only option which is somewhat less mobile (I know of and respect those of you who have no qualms hauling around much heavier, bulkier mounts, but just bear with me). So, as perhaps something of an implulse buy, the Castor was ordered directly from Berlebach. Why not another Ercole Mini, you may ask; I think it was to try something perhaps a bit smaller / lighter. Why not a Giro GR-2 Mini, you may then ask; I like the look of that one as well, and it has a discerning following, so I guess it came down to the Castor seeming a bit more substantial. Then why not a....shush already! But why directly from Berlebach? Well, they offer a version with the non-marring dovetail clamp ("with shoe"), which helps me through my bouts of OCD. But reviews of this mount are few - none that I've found, actually - and it's only through a response from fellow stargeezer @Stargazer McCabe (thanks Mac) that I managed to track down some actual user info - not positive. It seems that the Ercole Mini is superior when it comes to smoothness. Oops, I thought to myself, with the Castor already winging its way to me from Eastern Germany. Drat, should have sprung for another Ercole Mini. Oh well. I suppose I can return it. So it arrived today, and surprise: it's the Castor II! It says so on the tin. Even the Berlebach website doesn't mention this at all, so I'm at a loss as to what the difference is between this and the Mark I. But II must be better, right? First impressions are good. Excellent build quality, indeed a bit lighter and more compact than the Ercole Mini - but not much. Still substantial enough to instill confidence. And the action is...well, it seems just as good as the Ercole Mini was, at least in my memory. So is the Mark II so much better than the Mark I? Who's to say? There's much to attribute to personal preference in such matters and I have yet to use it out under the stars (it was delivered with the customary complimentary cloud cover). But I was in dread of opening the box and immediately having to fill in a return form and that I won't be doing. To be continued.

    My only clear night for ages was on the 12th November. The wind was very strong and I had neighbours insecurity lights going off all evening. Guiding was being upset by the wind and I lost a lot of subs but managed to get this. Any comments are welcome as usual and thanks for looking. Taken with ED80 and Canon 750d (unmodded). 28 lights of 300 secs at 1600 iso and processed in APP with some input of PI and PSP. Peter

    ....what all the fuss is about. Last night I was up in the Brecon Beacons again taking advantage of the clear skies and last quarter late rising moon. When I was there two weeks ago, I failed to find the Helix Nebula in the constellation Aquarius. I had gone to it quite late in my session on that occasion and lost a battle to observe it with a tree low down in the south west. Tonight I went to it early, star hopping my way from Skat (δ Aqr) via 66/68 Aqr and finally υ Aqr from where it is very close. First I put in my UHC filter and at 59x magnification using my 17.3mm eyepiece a large circular cloudy object could be seen. It was still quite faint so I then tried my OIII filter and it brightened up considerably. Although, I still couldn't make out the central hole that Turn Left At Orion shows in it's sketch. What is all the fuss about? After this success and with the OIII filter still in the eyepiece I decided to have a look for the Veil Nebula. I had failed to see it from my back garden a few months ago. I was using Sky & Telescope's Pocket Sky Atlas as my map and could easily see, naked eye, the star 52 Cyg which is on the edge of the Western Veil. Swinging the telescope to the star and lining it up in the finderscope I then took a look through the eyepiece. What a sight! I was completely blown away by it. Now I know what all the fuss is about. The nebula snaked it's way through 52 Cyg and beyond like a ribbon streamer thrown through the air, fanning out into a wide tail. Seen through the filter the nebula is really dense in places. It was thrilling to move the telescope's slow motion controls and ride along the stream from top to bottom. After taking in the view I was keen to try for the Eastern Veil. I moved back to ε Cyg and worked my way down the wing of the swan the short distance to where the Eastern Veil should be. A look through the eyepiece delivered another wow out loud moment. It was so long, arcing gracefully through the sky, dispersing into a wider nebula towards the bottom. I then spent probably the best part of half an hour switching between the two nebulae amazed at the sight. I tried to see Pickering's triangle but apart from my imagination I can't really say that I saw any defined shape of a nebula. I observed other targets last night, mainly galaxies. The usual suspects all looking magnificent under the dark skies. Nothing new apart from the galaxy C30, in a ridiculous attempt with my 8" telescope to see Stephan's Quintet. However, last night will live long in the memory as my first sight of the Veil Nebula in the same way that I remember my first view of the Orion Nebula. Fantastic!

    Captured this over the course of several nights in October. Can't say as I enjoyed imaging it much, it's an untidy nebula and an even untidier image! Scope: Tak FSQ 106 Camera: QSI 532 wsg Filters: Ha and OIII Baader 7nm Ha 22x30 mins OIII 13x30 mins Captured, calibrated and combined with Maxim and processed in PS Ha mapped to green and OIII red and blue It was a bit of a slog to process and in the end I think it looks best with quite muted colour. I think it should be called the Pavement Pizza Nebula!

    Cracking work Eric. I was going to comment that it was too large to be Uranus, but you beat me to it and edited that it was Capella. Loving your flame, horsehead and running man nebula images. Great capture of the Venus and Jupiter conjunction Ben. I'd completely forgotten about it until Terry texted me at 7am to ask what the bright "stars" were. Managed to dash out with the DSLR and grab a couple of quick images before they were lost to the dawn. It was a beautiful sight and a gorgeous sunrise

    Evening everyone I managed to grab what could have been my best run of the year last night. After a minor equipment issue (the arduino board running my focuser died) I managed to get a good few hours of imaging done. M33 - 12x300s @ ISO800 Iris Nebula - 15x300s @ ISO800 Elephants Trunk Nebula - 25x30s @ ISO800 These are far from perfect and I will be reprocessing these once I finally save enough for PI, I also intend to add more data to these as well

    On Friday my third used Canon 60D arrived from Amazon and Saturday night the sky cleared and I finally got my triple rig together consisting of a 60D on a Samyang 135 f/2, a 60D on a Canon 300mm f/4 and a 60Da (the factory modded version of 60D) sitting on my ES 127 ED apo, all on an EQ8 mount in my obsy. I went for two targets, starting shooting at NGC7000 around 7 pm and then at midnight it was getting too low so I shifted to IC348. I was of course asking for triple trouble but I got some useful data to process. All was supposed to be at ISO1600 but after a meridian flip at 01.30 I forgot to turn down the 60Da from 12800 ISO (used for focusing and framing) to 1600 ISO, so there I lost 4 hours on one camera. Also, after changing camera batteries the 60D sitting on the 300mm decided to change from f/4 to f/5 without asking me, which explains the rays around the brighter stars on the IC348 image form this lens. I show three images, one from each scope. NGC7000 & Co from the 135 Samyang. This is 169 x 1 min. A really nice little lens with very little aberrations. The 60D is quite good at picking up Ha even if it is not modded. IC348 with the 300mm Canon. 63 x 3 min. Unfortunately not at the native f/4 but accidentally at f/5 as explained above. Not sure I like what the internal iris does to the stars, so next time I have to make sure it is set on f/4 (or stop it down with filter rings). There is an odd green thing in the middle of the image. I eft it there since I have no idea what it is or may have caused it. IC348 with the 5" ES 127ED apo. Unfortunately only 8 x 6 min (due to my ISO setting miss hap) but it is clearly a cool target that deserves another go with plenty of subs next time. Top of my list now. SQM was 21.0 but there were probably some tiny ice crystals in the air that particularly affected the refractor images. Temperature was ca -4 °C and I soon had frost on everything except the heated front lenses, as seen in the picture from next morning. Comments and suggestions (including what the green thing is) most welcome! Cheers

    Well there have been some great threads on here, loving the one regarding the neatest/untidiest workstation. Many people are really OCD about tidying up their cables for imaging. I on the other hand couldn't give a stuff as I am always derigging for astro camps and changing kit around I'd be forever unravelling cable ties. So I just let it all hang out, but just make sure nothing is snagging. I wonder who could beat me. This is not the best shot as I didn't take one specially for this thread. But this is what I get with a dual rig. Cables just tied back initially. Carole

    Hi I am still about just not done any imaging So I though I would have a go at narrow band imaging ( my first ) This is the Heart nebula in the std hubble pallet ( SHO ) and the first image with my new Tak 106 there is about 3hrs in 10min subs in each channel and off course was processed in Pixinsight , could be better but I am happy with it for a first go Please see here for full res version http://www.harrysastroshed.com/image html/nebula HTML/heartnarrow.html Regards harry

    Well it was a good night, weather-wise, last night (12-Nov-2017) in this part of Oxfordshire. Cool (3 degrees) but amazingly dry, really (85%.) And so, for once, everything wasn't covered in dew by the end of the night. After an earlier debacle with coma-corrector spacing, I've shaved off a further 0.5mm to try and tweak it a bit better, but I've also (for my sins) started a trial period with PI. I've so far eschewed this box of tools in favour of simpler, and some home-grown, things. But I'm interested in finding out more about what so many people use... even if only to understand the PI-speak language a bit better. As a result of all this, I want to try things out on some smallish datasets, and ended up with: Crescent, 12 x 300s (60 min) Pelican, 17 x 300s (85 min) Iris, 12 x 300s (60 min) Horsehead, 6 x 300s (30 min) Quattro 8" on Avalon M-Uno, QHY8L OSC, captured, guided, and dithered, by Nebulosity, pretty poorly processed in PI (my fault, not its) including bias, darks, and flats. Some observations about the images: Crescent... a difficult RGB target, I've tried but failed to reduce the background stars Pelican... just a bit too big for the frame, but the extra data (more than 60 mins) helps with noise Iris... real problems with the background. The APS-C sensor is just a bit too big for this scope? Horsehead... my first ever attempt at this. Pleased to have resolved the Alnitak double. Sad to have framed it so poorly for the Flame. No doubt the processing is very ham-fisted for my first use of PI, so any C&C is positively encouraged! Thanks for looking.

    I'm still a traditionalist and like a good star chart, although some software out there like sky safari is very good. One of the mob uses a nexus with his phone and it is really good, whilst another uses the ipad as a reference. NGC 7331 is a wonderful galaxy in it's own right but managing to pull even a couple of the members of the quintet out will be challenging but very satisfying. The quintet is also known as Hickson 92 and there are quite a few others you may like to try such as Seyferts sextet, the box and Copelands septet to name a few. Look them up they also fall into the Arp atlas too. I hope to be looking myself over the coming week and a half with the rest of the mob in the isle of skye. Happy hunting

    Boring? Start the run then wondering if the neighbour is going to put the rubbish out and set off his backyard floodlight, will the USB connection drop out? Will the cloud roll in? Will the guide scope dew up? Will the mount throw a wobbly? Will an aircraft or satellite wander into the field of view? Will the run finish before the scope starts to image the roof of the house, trees etc or Mrs Sitech cooly declares “mount approaching meridian limit”? Trust me, there is never a dull moment....

    That's where I think a smart phone or tablet with SkySafari can be really useful. You can easily fine tune the display to a certain field of view, orientation and with the limiting magnitude of the stars visible set to match what you are seeing. Makes it much easier to focus in on the particular target. In this instance shown there is a 1 degree fov and stars down to mag 14.0, correct image and the Quintet centre of field.

    Hi everybody. As the title says this is a first light with my new setup. Data gathered last night. Usually when i get a new bit of gear it takes some time to get everything working as i would like, but this just seemed to work from the start. No software or hardware issues. In fact the only issue i had was a lack of thumb screws on the rotators which was sorted with the thumb screws from a couple of serial cables. Ngc 1333 is a reflection nebula in the constellation Perseus. At about 1,000 light years from earth the dusty region extends from the California nebula all the way to the Pleiades. The large red and blue nebulosity in the top left of the image is IC348. This is one of the closest stellar nurseries to earth, with stars as young as a million years old. I captured 5 hrs of Lum with the Asi 1600 at gain 0 cooled to -20 5 hrs of Rgb with the Asi 071 at unity gain -5 Captured using SGPro, stacked in DSS, processed in PI and PS. Hope you like it. Richard.

    Under the skies you had some of Stephans Quintet will be visible in your scope. Try the 8mm Delos and the 5mm XW, swinging the scope a bit to pick them up. They are faint...and can pop in and out of view, depending on the telescope. Pickerings Wisp is big and likes a wide TFOV- I use a Lunt 20mm HDC these days and it works really well and will illuminate your eye a bit better than the 17.3 Delos. Great report BTW!

    Nice way to put it Sounds like the way that (so far) spotting the Flame Nebula has been my gateway object to not seeing the Horsehead Nebula

    Sounds easier than my experience. I thought I'd found it through the finder quite easily with a quick star hop. However I then decided it didn't look planet like enough - not sure what I was expecting, it didn't look very planety in kielder either. I then proceeded to star hop to it twice via different routes. This turned into 20mins of checking and double checking Stellerium on my upside phone (I don't have a raci so this makes it easier) I then pushed the mag to check I got a disk (it seemed very wibbly last night which made it difficult to decide if i was focussed when on the higher mags). Once I'd done this I spent several minutes wiggling the telescope as it seemed help bring out the colour (anyone else found this? I noticed it whilst nudging the scope around) I then set about comparing it's apparent size and brightness to a nearby star of a very similar magnitude. At this point I decided I had indeed found Uranus. Took me about 40mins - sober believe it or not.

    First time mono with my 130pds, asi1600. 15 sec exposure at unity. Messed up and my focus was out and my L,Ha,O111 and S11 failed. R x 20 G x 20 B x 20 Flats, Bias but no flats.

    @ollypenrice @wimvb @Rico @Philip R Good evening, Well, I said I would report back with some results after some tampering. From all of your feedback, the prime suspect, and easiest to amend to start off with was omitting the focal reducer from the light train. So, I went through, every thing the same as I did before as best I could. Same number of flats/bias/light/darks and used the same processing and stacking routines in PixInsight as I did before. I used M27 as a target too, so I could get as good a comparison as possible. I'm really pleased that in this instant, the halo effect has disappeared, and then image is fairly uniformed throughout. While this is obviously a massive improvement on the first image, I also have data on another 3 targets from last night. One set of which is for M45 which is another image that had issues with the phenomena at my last attempt too. I doubt if I will have time tonight to go through the stacking and processing routine, but I will finish it off some time this week before declaring it a 100% success. Even though in this case I have only omitted the FR from the light chain, I have on order a UV/IR filter too which I will introduce into the kit in an attempt to improve things further. My thanks to everyone who has contributed and made suggestions to help me. It's truly appreciated. When I finish the M45 image, I will add that to this thread as a comparison too. Thanks so much, Tony

    Noisy Screenshot from last night, swopped mounts and scope took this with the Skywatcher ST at f5 so pleased I managed to get them both in, must start learning how to process haha ( not bad as the refractor is neither doublet or triplet hence the star halo's)
