Explore Our Local Group
This is a list of the Galaxies that form our local Group. I have an ongoing project to locate and identify these. Find for information and develop a summary description of them. I have been capturing images when I can and provide links to them in our portfolio section.
The information provided here is gleaned from Internet sources including Wikipedia. I also provide an update related to my success in observing the item, including links to my Observation Log and other posts on this site. All related portfolio posts are tagged with the "Local Group" tag.
