I would like to introduce this particular work on one of the galaxies in our Local Group. This is NGC205 or M110, satellite galaxy of M31.
The peculiarity of this galaxy is a presence inside of some dust clouds, symptom of star-forming regions. This is in contrast with the type of galaxy as cataloged.
The long integration has allowed the identification of these clouds and the central region of star formation, thanks to a long elaboration on the colors.
WEB page also show a much stretched image to highlight the tidal interaction with M31
I hope it will be interesting:

All the best and thanks for looking,
