Bubble Galaxy NGC 3521

[furgle]

The large and bright Bubble Galaxy, or NGC 3521, is located in the Leo constellation, which is quite north in the sky for my location. Upon seeing a fantastic test exposure, I could not leave this galaxy alone.


Shooting between trees and through clouds, over 5 nights, the galaxy slowly resolved into the image presented. There are various shells surrounding the galaxy that are most likely from mergers and interactions with other galaxies.

Hi Adam,
that's incredible to catch from an orange zone in a city -
Mag 11 is faint.

I checked it out & Hubble has a close-up:
