Object name: HOLMBERG I
Holmberg I is the first of 9 dwarf galaxies in Holmberg's list of dwarf galaxies, most of which lie somewhat in the area of M 81. Holmberg 1 lies about 2.5 degrees northwest (330°) of M81 and is considered part of the M81 group. It is a very blue, low surface brightness dwarf with little HII emission according to papers I read. That surprised me as the HST image shows some nice nebula in it. Then I noticed the filters used by the HST, Green (centered on the same frequency as most green lasers, 555nm) was assigned to blue with near infrared, 814nm, was assigned to red. Thus the blue nebulae were seen in green light rather than H alpha red. They show as blue fuzzy "stars" in my image and are quite weak in red light. I need to revisit this one in H alpha sometime.
