Description

https://lindasastronomyadventures.space/?p=11061I'm continuing the journey through the prominent galaxies in the Messier list as we get into the later part of galaxy season. I'm looking forward to adding in Milky Way nebulae but still enjoying getting up close and personal with these galaxies!
