M83 appears to have a lot of noise which you’ve tried to suppress but a nice image just the same ( maybe a tad too much blue saturation )
Just to put things into perspective Peters rig is super high end equipment +$60k stuff plus his 16” RC scope weighs 52kg without imaging gear , that’s a beast of a scope let alone the precision optics. Pete’s image is a cracker but he has the rig to achieve that sort of resolution and yes he is in another league.
Your images are fine , your equipment is fine , processing can always be improved and you can always capture more and better quality data too. This AP hobby is a continuous work in progress year after year
Well done !!

Thanks Martin, I appreciate those comments. Yes, M83 was really noisy and did what I could. I agree that the image would benefit from toning down the blue a little in the galaxy.

When imaging broadband, I get some gradients that my flats eliminate reasonably well, but with NGC 4945, the flats performed far better than usual. I was surprised at how clean the calibrated subs looked, as well as the stack of only 1h30. Hopefully, I can replicate similar quality flats and that might help future broadband images. Since this image, I have attempted to fix the double diffraction spike. Results pending, stay tuned.

Thanks again for your helpful comments.

Thanks Dave! I hope to get more data on these one day. There is always the dilemma: more integration or new target?
