I'm not sure I'd be using a filter wheel with a DSLR camera setup tbh

Yep I had similar things and I remember starting trying to aim for 5 plus hours if I could...the 2600MC blew me away when I got my first sub out of it, totally different animal so don't compare the two too much.

Is your camera modded? Just looking at that and what I managed with a modded camera in just over 2 hours of data and your picture looks great in comparison so well done. It has also been pretty warm lately which my DSLR hated when I was using it in the warmer months. I think I also was using longer 4/5 min subs as well but that has its own problems. I think, if I'm reading it correctly, that tutorial is using a 2600mc pro which yes will have substantially different to your DSLR

That's mega, well done!!

Yep, after watching a number of videos people had similar things with ABE

Been awful this season tbh looking at subs there is some from September and then some from December work hasn't helped in that regard despite WFH

Yes starting to see this now. So below is what spat out after DBE playing around And seems flats have done there job here, some light processing gets me the below which isn't too shabby....PixInsight is a little new to me but then, everyday is a school day

Not in a completely dark room no but I may build a box to help next time

Not sure...I've taken darks for the M31 set as well so going to have a play with that and see what it does.

@vlaiv so managed to get the camera off, lens cap screwed in and new darks taken. Re-using the older flats To my eyes the older flats now seem to work much better with the darks than the new set I took but still not quite there. So having a mess around and using DBE instead of ABE with a few points gets me the below, which looks MUCH better. Cropped and a little finer placement gets as always, processing is hard lol

These were taken on the scope yep, refractor with the lens cap on...I'll bench it and take them again and see what I get.

@vlaiv I did actually manage another target that night for which I do have some darks for (only 40 mins of data mind). Doing all of the above, STF stretch and ABE spits out the below The correction seems better, below is without flats and dark flats. I'm wondering if i've caught some clouds in the stack somewhere

Thanks @vlaiv i'll sort out some darks for that and take another stab at it

Yep had dark flats but no darks for these...tbh darks on previous shots haven't really been needed

Hello, So hopefully someone can help me here. I've been using my 2600MC pro a few times now and mostly it has been fine until the other week when I decided to have a go without the L-extreme filter. I set up everything like I usually would and started capture on M31 to see how it fared with my previous attempt and the DSLR. Managed to capture an hour and forty minutes worth of data but my flats seem to be messing up, I have re-taken them but it's still not right. I am using the APT flats aid which has given good results previously. Below is the stacked (DSS) image with STF stretch and ABE in PixInsight (lights, flats and dark flats) Below is a single light frame Current flat used to create the image above I am guessing I am doing something pretty stupid but can't seem to work it out. Any help would be appreciated.
