Hello
A couple of nights in January and a couple in February allowed me to capture this nice face-on galaxy in Ursa Major close to Tania Australis. Quite a few reflections from the bright star to deal with in the older StarFire EDF. The newer Stowaway seems to have dealt better with the brightness although I was shooting half the exposure (at 5 mins OSC). Taken using the usual tandem arrangement.
There are many, many background galaxies in the annotated version. A cluster of background galaxies, towards the lower centre right is ACO 971 which according to Simbad's database is 1.3bn ly away.

Lovely image but very tiny in your FOV.
Great work as usual.

One of my favourite galaxies
Your cropped version looks great
