Telescope: Apertura 72mm Refractor
Camera: Canon EOS M50
Filters: Optolong L Pro
Took about 37 mins of M82 and M81, only darks and bias frames no flats. I do not have the field flattener yet and because I couldn't get my guiding to work my target drifted to the top right where stars got stretched out. Im not really good at processing either so here is my best attempt! I'm open to hear more tips to make my image look better!

You can use Siril's background extraction tool to even out that gradient. Besides that the image is looking great, especially the Cigar galaxy.

It said plate solving failed

#

Maybe try the other one

#

Highlight the background and then highlight a white area like the core of bodes galaxy

Yep

430mm focal length 3.72 pixel size

I’ll try and mess with it and find the problem

#

Maybe checkmark the downsample box

Nows it all red

Bruh

I tried background extraction and it wasnt blue

#

I used color calibration

#

Maybe try this. For the top one highlight a mostly empty bakcground area, and for the bottom one highlight a bright area of one of the galaxies

#

its the one above photometric

#

The color banding is still visible

#

darn, i dont know what would cause that

sinful dagger
#

will probably go away if I dithered and used more images

#

Its my first image and im still very happy that I can see the galaxies

#

Thank you for all the help!
