First time using the AT60ED. For once I did not get the dreaded "Red/Green rings of death" from the D5300 but there is a weird mottled red patchy background (not sure if Noise reduction caused some of this)
Had a really hard time getting focus with the new focus mask and ended up eyeballing it, so it's definitely not perfect
Also around 3/4 of the way in, a black splotch appeared in the subs that was NOT in the first ones, OR the flats. I didn't touch anything and it was in the same sequence so not sure about that...
Had some great PHD guiding but I am still not happy with the stars. Also the first time with the field flattener -- It looks like maybe some star elongation but it's somewhat hard to tell so far.
I also feel like I blew out both main galaxies, yet I see a lot of recommendations to go to 10+ min subs (maybe with filters ?)
Any advice on pulling the details out, appreciated (non-modded camera and no filters)
This was the FIRST clear night in 2021 so even though the moon was out, I grabbed the chance and am reasonably OK with the result.
My focal length is obviously a bit limiting for galaxies but it's definitely an interesting challenge
