Oh, didn´t know, will remember it for next time, cheers!

Ill add my final edit too, played with curves and levels, a bit of saturation and crops here and there: Loads of noise I know, but Im happy with my results. Again, thanks everyone and Clear Skies!!!

Looks really cool, and will definitely use that method and test it out. Great job given the data. Thanks!! Yes, after this, flats will be a MUST in every session, glad to have learnt the lesson, even in the hard way haha. Great image, really like the sky color you got. Will look into it! Ive never used Siril, but the image proves I really should, will take everything you said into account and will try to learn Siril and edit it again. Many thanks!!! Yep, image is prefectly salvageable, thanks a million Ivor.

Yes, but the only calibration frames I managed to get were Bias, as my camera died and ended up only taking lights

Yes, exactly.

Alright, have been touching sliders here and then and reached to this: Looks much better, but theres still that vignetting, will continue messing with it hahaha

Hello, Went to a trip to a Bortle 3 sky last december, just got time to start processing and all. Stacking went fine, there were about 34 lights of 2 mins and about 30 bias (couldnt do darks because battery ran out before I could start doing them, no flats either for the same reason.) The bias were taken the day after. So, about an hour of exposure of M45 with a canon 550D, 55-250mm at 135mm and ISO 1250. I thought i had some good data to work with, however, im starting to process it and it looks like it wasnt as good as I´d thought. Whats really bugging me is this vignetting: All I´ve done is adjust the black and gray pointers in Levels, but i get this ugly red haha. Stacked file is: https://drive.google.com/file/d/1sm-_MVfILDNd9aMexPY5KDnjoepCaOZ8/view?usp=sharing Thanks in advance and clear skies!

I would definitely have calibrated it but my camera died on me 😞. It's a very nice edit Vlaiv, you really managed to take out that strong LP gradient. I tried quite a lot but I'll have to dabble with it again hahah. Thanks for all the info and the time you spent on this, I really appreciate this. Will try to edit again to try and reach something similar to yours. Thanks again and clear skies!

Right @vlaiv, will attach as soon as I reach home, sorry for the trouble.

Hey there, recently went to a dark sky trip last friday and although the imaging session got cut short (due to battery issues...you should make sure they're charged btw😅), had an amazing time under the stars. Now, I knew I wouldn't get an APOD image, but i was really hoping i got something good, cause the place was quite dark and the tracking was just on point...However, after reaching home and stacking and processing, I don't see as much detail as I was hoping to. I dont know if its because of the quality of the subs or my editing skills, but I cant seem to bring out much of it without completly wrecking it unfortunatey. So, I am asking if you could try to edit it for yourself and tell me if its the image or my (albeit basic) processing skills. Processing I do with gimp, so if the methods are aplicable to it too, that'd be really great. Stacking was done with sequator I've heard its better for wide-field, if this is not the case, please do let me know what you use Thanks in advance and clear skies!!! output.tif.pp3

Hmm I see, will stick to what I'm using for now, and try to "master" that before jumping to other software, Thanks and have a good one, S

Thanks Vlaiv, for such a detailed and well explained message. Is imageJ easy to learn? I'm still getting used to GIMP and am now starting to properly use StarTools.

Thanks Vlaiv, that's a great image. I didnt do flats, but I plan on learning how to do them soon. May I ask how and where did you process it? Thanks again and clear skies, S

Okay, almost thought I had wasted another night. Thanks, I will try what you say.

Will do for sure, that stacking time won't be wasted

Some background, as you can see, it's the orion nebula and neighbourhood. This was shot last night at ISO 1600 canon 550d. With a CZJ 135mm stopped at f3.5 I believe. (first light with this lens by the way). There are 58 frames at 50 seconds each, after discarding about 30. I also took 10 bias and only 15 darks because my camera died :(. Is this image too bright? Should I process it or did I mess up some DSS setting. I used Kappa sigma clipping and abour 54% treshold. Thanks and clear skies!

By the way, just picked up the Carl Zeiss.

Oh man. At least I'm sure you'll take full advantage of clear nights.

Yup, but it said the same yesterday and well... couldn't see polaris at all so couldn't do anything really

Awesome. Good to know I'm getting a good deal. Will for sure take my camera dn check if it fits with my uhc clip in. Let's hope it stays clear for tonight 😁😁

Yup. Uploading right now

Hey @alacant I found one second hand nearby. It already has a canonaef adaptor. Will it reach to infinity focus?
