Hello Marnus,
I'm not sure if these are full images or crops?
How many exposures have you taken for these images?
Anyway here's some tips:
1. Take flats to get rid of the vignetting. There may also be some other light interference? You can get rid of vignetting using gimp or photoshop - but that is harder and not as good as flats.
2. Take more exposures. 60 - 90 x 30 seconds is okay to start with for brighter objects, but you'll notice many of the great images are hours of total exposure.
3. You can use "lens correction" in gimp or photoshop to help correct the star distortion at the edges - but this must be done on an uncropped image.
4. Get the polar alignment as close as possible to avoid drift.
This will help to start with - then you can learn more about exposure times, processing etc.
Regards,
Tony.
