Description

NGC 891 - an edge-on spiral galaxy which is 30 million light-years away in the constellation Andromeda. The galaxy is estimated to be around 100,000 light years in diameter.

This is data from my home observatory captured between 20 and 30 December 2016. I used a Skywatcher Esprit 120 telescope and QSI 690 camera with Astrodon filters. Mount is a Mesu 200.
