M77 & NGC 1055

Two galaxies in the same field of view!

At the top left, large spiral galaxy NGC 1055 joins spiral Messier 77 (bottom right) in this telescopic view toward constellation Cetus. The narrowed, dusty appearance of edge-on spiral NGC 1055 contrasts nicely with the face-on view of M77’s bright nucleus and spiral arms. Both over 100,000 light-years across, the pair are dominant members of a small galaxy group about 50 million light-years away. At that estimated distance, M77 is one of the most remote objects in Charles Messier’s catalog. The field of view is about the size of the full Moon on the sky and includes colorful foreground Milky Way stars along with more distant background galaxies.

I took this image over 14 hours. There were 14 Luminance images of 30 minutes each and 7 images each of 20 minutes for Red, Blue & Green colors.

I have some collimation (alignment) problem with my telescope making the stars look rather strange. It’s being fixed shortly.
