cool ty ill look around for a t junction and stuff. would mean almost one less wire

i like it. its better than i've managed. i think this might be a tricky target for those new to the hobby like me, so really well done.

Vroobel has been extremely kind in letting me have some incredibly nice data to practice processing with. Just thought i'd post this here for reaction, etc, with Vroobel's permission. id call this a first pass to see what potential is there. Compared to Vroobel's own version on astrobin i think my processing of it is very much lacking. just to be very clear, this is Vroobel's data (darks lights bias and flats) and just my stacking , processing and developing in Siril, graxpert, and a little gimp. Not even astrosharp yet.

Is there a power extension lead I could attach to my mount power supply so it could still power my mount and then run up to sv605cc? Ideally via a second extension to that lead so I detach it from stuff more easily? Would it be able to supply enough juice to both? https://www.firstlightoptics.com/batteries-powerpacks/lynx-astro-12v-dc-5amp-low-noise-mains-power-supply.html Some sort of t junction, then then one more shortish extension lead? If not, I guess I could try the mount on rechargeable batteries

apologies for 4 pages on "i need help buying a cheap astro cam" i wasn't expecting to need this much help and advice on what i thought would be a relatively straightforward thing. sv605cc uses the imx533 sensor and includes what im guessing is all the bits i need from the flattener back, to get back focus. https://www.svbony.com/sv605cc-camera/#F9198K doesnt seem to include a power supply, of course it doesnt.

your results prove how good it is, but i have the filter issue and rotation issue to also deal with and a modded dslr won't help me with that

im looking a the site atm, and £95 is a good deal, but it doesn't help with my rotation or uv/ir cut or nb filter swapping i'd rather keep the £100+ (postage there/back) and put it towards a proper astro camera, rotator and filter drawer.

Sv605cc is £530 on their website. That's a boatload less than zwo version. Might be doable maybe a get a rotator that doesn't use m68 elsewhere. This is a multiple pita

Hope so but no way of knowing. I think going forward I need to be able to go at 30minutes notice.

Nah it felt a bit dubious using the nose piece held in by two screws no compression ring. I did have a go loosening/turning the focus tube adapter and flattener about 3/4 of a rotation but then optical train felt floppy and probably puts stress on the threads

I think so far in the last month I've taken 15 minutes of usable subs. Thank god I have cheap light easily quickly grabable gear ;(

I tried using it on the moon even mono it looked pretty nice. I really do believe you about time on target but as I've already rotated my camera it will be hard to add to my few existing projects. Pinwheel galaxy is small enough in frame for it not to matter but not much else apart from medium galaxies, which my gear is hardly ideal for.

I do realise total integration time is vital. But with no astro dark right now and maybe only 1130 to 2am being darkish it will take three clear evenings for me to get 6 or 7 hours data. That might mean 3 months

The only place I can fit a filter is, maybe, at the back end of the flattener. And it's tricky and inconvenient to put in and out. I've had to rotate my OTA in it's rings to orient my dslr to upside down so that the guidescope doesn't almost hit the screw to lock the OTA dovetail which make it tricky to tighten. I'm concerned it might slide off the Dec attachment thing. Currently I'm on here summoning up courage to try my semi bodge job of removing them attaching finder clamp to my spare dovetail, then that dovetail onto the top of the OTA rings. Also dubious about it then not working when it looks like sky might be clearing for first time in weeks. Maybe another day

In the post today I got a bag of five M4 bolts. I won't post a pic

also probably not from svbony, there advice seems dubious, but im hardly an expert so...they tell me to buy some rather random looking set of adapters from amazon that don't even seem to include an m68 for their camera rotator. 1. As for parcels to UK, we can provide the free customs clearance shipping method. So clients do not need to pay for extra vat or import taxes any more. 2. As for the items you may need, pls refer to the links below: SV705CC-SV226 filter drawer https://www.svbony.com/sv705c-color-planetary-camera-imx585/#F9198J-W9184A camera rotator https://www.svbony.com/sv210-caa-camera-angle-adjuster-for-sv550-80f6/ uv-ir cut filter 1.25" https://www.svbony.com/uc-ir-cut-filters/#F9127A 3. As for the SV705C camera, since it is designed as a planetary camera, so currently, the adapter for it is not enough as the dso cooled camera. I am afraid you may need some other adapters https://www.amazon.com/Starboosa-Telescope-T2-Extension-Cameras-eyepieces/dp/B08V923KS3/ref=pd_ci_mcx_pspc_dp_d_2_i_1?pd_rd_w=Rhgsb&content-id=amzn1.sym.568f3b6b-5aad-4bfd-98ee-d827f03151e4&pf_rd_p=568f3b6b-5aad-4bfd-98ee-d827f03151e4&pf_rd_r=SXG8S62K1YVEKPX58N2Q&pd_rd_wg=gYC2f&pd_rd_r=4dbb2126-2d9f-4c38-9a8a-b3a03b39baa6&pd_rd_i=B08V923KS3&th=1 i might email flo see what they say. thanks again all for looking at another dumb thread of mine and for all the help.

533 doesn't seem to have a non cooled version and the zwo533mc pro is almost £900. 585 non cooled is my only option i think

yeah i was having similar thoughts. i have a few jours left of my 1/4 day off, today, so ill go watch some imagers using it on youtube. really haven't done any research on it because its not hip to be square put me off. but it does leave mosaics open as an option. i really want to take a nice image of m31 when it gets higher in the sky and its fits perfectly in my current fov but even with a 585 i'd need to do mosiacs anyhow to fit it in. i also got a few bolts and nuts so gonna try attaching my guide scope bracket to my dovetail and mounting it on ota rings first

not really interested in planetary but i've seen some nice results so it would be nice as an option. but nebula and big galaxies is pretty much all im after for now

i've had nothing but encouragement from you and everyone else on this wonderful website. its impossible for me to express how much i appreciate it and how its responsible for me going from to this in less than four months. and on a tight budget.

the next cheapest option is a square 533 sensor and i think there are only cooled versions of it. probably twice what a non cooled 585 would cost me. right now im not keen on the square aspect ratio it reminds me of poor quality 1980s television too much. ill start looking at people's images with it see if i like it more. i could a more sciencey hubbly look to it i guess. looking again at the horsehead nebula above with fresh eyes this morning, the 585 does possibly appear a bit 'claustrophobic'.

i can't use a filter drawer with my set up and i don't want to regularly put in and take out a filter into the back of the flattener. im likely to smudge it or worse if my dslr was modded i would still want a filter drawer. also i haven't even looked at how to process nb data yet or maybe combine broadband and nb. also, also, i was bored and rotated ota in its rings so its back to normal, but this means my dslr is now almost upside down. if i unthread the flattener enough to rotate the dslr back to 'normal' it gets very wobbly. so i also need a rotator....that i can't use with my current set up with my dslr even if you were the sole voice warning me, i've seen your images and help/advice on other threads and take your advice very very seriously. im trying to deal with multiple "minor issues" in one go for as little cash as possible right now and uncooled 585 and some accessories for £300 seemed a quick easy win. but i got a reply from svbony earlier and ill post about it soon as i get a chance

not sure how scientific this comparison is. i thought my rayleigh limit was about 1.6

no need at apologise at all. i have considered it but it costs at least £200. for not much more i can get a modern low noise sensor camera (sort of) designed for the job. and smaller and usb powered so one less power lead to manage. the smaller field of view is definitely going to be an issue, especially as its going to take time just to learn how to process mosaics, let alone be decent at it. an imx533 would be a wiser choice, but there's not a lot of other budget choices. i can concentrate on the smaller juicier nebulas i have been looking and comparing a lot on telescopius for lots of objects and i agree its a pretty major issue, but im on a tight budget and 585 is probably the least worse option. at least it will help with smaller galaxies... another issue could be my guiding. last session it was 0.8" so should be ok, but it if reverts back to 1.5 ish could be problems.

i think everyone who reads this and doesn't live in the north of england should do the decent thing and buy themselves some new astro gear right away and choose next delivery.
