NGC 891 is a beautiful spiral galaxy which is seen perpendicular to it’s rotational axis, so we see it edge on.
It is located in Andromeda, so there are many foreground stars.
I have seen it in telescopes as small as 15cm aperture, in my 250mm the dust lane becomes visible, but in a larger scope, like the 40cm I recently observed with, it is a really beautiful sight. But of course not as detailed as in this image.
