Galaxy M77

M77 is Galaxy at a distance of 47 million lightyears and 100.000 ly big. I did try to make a good picture of M77 but the exposure time was to low. Anyway the picture shows some detail and I can't wait untill a next time...


M82 ASI224MC

First time that I'm able to take a picture of M82. This galaxy is about 11,4 million lightyears away from us.
The picture was taken with my ASI224MC on TAL200K. In total 11 pictures taken each 30s exposure. Manual stacking and editing using CS4. The image is not that great but still comparable what textbooks describe.
