The Whirlpool Galaxy, about 30 million light years away, displays the classic spiral galaxy structure. It is interacting with the smaller NGC 5195. Their ongoing collision and eventual merger is a process that will take many millions of years.
I got about 4.5 hours worth of data on M51 in early April 2021.
With my kit camera lens, I was limited to a fairly widefield shot. But I like how it looks! And I didn’t find it too limiting. If you zoom in, you can see some nice detail and structure with the spiral arms of the galaxy.
