Thanks @alacant: Really appreciate your feedback..Im not very technical so I dont think I can comfortably make many of those changes but I do dither and I will try skipping Darks!
@vlaiv, Thanks I do quite at a bit of noise reduction on Pixinsight so I could be that...but If I leave it the picture will be quite noisy... I am thinking of not running noise reduction on Pixinsight and use Denoise AI instead.? Any suggestions on what I could do instead?
Thanks,

Hi Everyone:
I just recently modded by DSLR and really happy to see much more red in my images. I tried taking a picture of the Heart nebula. I have an 8 inch 3.9F Orion Newt, powered by ASI Air Pro on a CEM 40 mount.
I am really happy with the final picture, but im a novice on Pixinsight. If I zoom into the stars, I see like long strands over the stars (like greyish roads?) I'm not sure what they are. Are these artefacts of some kind?
Any ideas on how I can create a clearer picture between the stars?, would really be appreciated.
Thank you in advance!
Best regards,
Kam

Thanks @alacant! I’ll give it a go indoors to try before running a tea test (if the clouds ever go)

Thanks @The Lazy Astronomer, I get your point.. so is it expected to see vignetting in the flat image when I take then? If you have an example of a good flat?would you mind sharing?
I tried taking flats using a light box but since it’s connected to an ASI Air pro, the camera needs to be on Manual mode, hence I can’t use the AV method. So, I try taking exposures with different exposure lengths so the histogram more or less is in the middle.. I think I didn’t try hard enough
Thank you!

@TheLazyAstronomer I used the recommended DSS settings but I believe my flats might have been on the bright side, Im using an ASI Air Pro and the histrogram was quite wide and around the half way mark.
So ideally, we dont want to see any vingetting in the flats, correct?
Thanks again!

Attached is the master file @The Lazy Astronomer.
From your experience, does it look okay? I used an Light box ontop of my newt, which had a t shirt over the top.
Thanks for your help.

Hello Everyone:
I hope all is well.
My a newbie in Astrophotography and attempted to take a picture of the Dumbell Nebula. I took flats using a light box, stacked in DSS and started some processing on GIMP. I can see its darker on the sides. Is this a vignetting issue or something else (e.g gradient)? Any suggestions how I can tackle it and how I can improve my processing are deeply appreciated... thank you!
I live in Denmark in a Bortle class 4 zone. However, its summer so I have very little dark hours and even then its not totally dark. Also moon coverage was approx 60% at the time.
- Telescope: Orion 8 inch 3.9 FL
- CEM 40 Mount
- Canon 800D
- TS Optics GPU 1.0 Coma corrector
- ASIR AIR Pro for image capture
Image
- ISO 400
- Light: 180 Sec x 40
- Flat: 30 using a white box
- Dark: 30
- Bias: Unfortunately couldn't take it as battery died
- Stacking: DSS
- Processing: GIMP
Thanks everyone!

Not sure if this is just Halo's or Noise? Any ideas how I can fix this on Pixinsight?

@vlaiv, Thanks for your input really appreciate it. I have started to run initial noise reduction on Pixinsight and then finish off with Denoise Ai which works really well.
