NGC 891 - spiral galaxy in Andromeda



NGC 891 is an edge-on spiral galaxy with a clearly visible dust lane. It is located in the constellation Andromeda, near (3.5 E) to the well known double star Almach.
For the first time I tried to take picture of this excellent galaxy almost ten years ago (with smaller refractor and DSLR), still to be seen
here, and the progress is (I hope) obvious.

I can also present here the picture of NGC 891 in full resolution:
