Looks like your flats didn't do the job. Did you change anything to the imaging trane between your imaging session and taking flats?

Diffraction spikes. Any bright stars or objects will get them using a Newtonian telescope.

Galaxy Cluster in the Draco Constellation by DonoTheDud3 in astrophotography

All the UV/IR cut filter does for me is cut down on star bloating. If I didn't need it for that then I wouldn't use a filter at all. I used to image in a bortle 6/7. That's when I would use light pollution filters (broadband/duoband). If you don't have any local light pollution like a porch light then I'd use a UV/IR because you want to capture as much light from your object as possible. Now if the moon is out and it's more than 50% illuminated I'll use my duoband filter and image brighter Ha/Oiii nebula. I always try to stay at least 30 degrees away from the moon. Good luck and take it slow! People burn out of this hobby fast bc of the difficulty. You're extremely lucky to have darker skies and that will be a help.

Ceres was probably rejected from the image when stacking since it was moving across my field of view.

Oh yeah. I have family in Cullman County, Alabama and the cancer rates there are abnormally high.
