Messier 81 and Messier 82. First Published 02.21.2022

 Last night, I decided to take some images of close galactic pairs. The first is Bode's Galaxy--a spiral (M81) and The Cigar Galaxy(M82), which looks like a cigar. The proximity of these galaxies is not line of sight, they are actually gravitationally interacting. Between the two is a nebulosity called the Integrated Flux Nebula. It is very faint and difficult to image; from inner city skies, imaging is almost impossible. This image is a cropped version of a much wider field captured by the RASA. The Cigar is a starburst galaxy and has been deformed by the tidal forces from M81.Stars are forming in M82 at about 100 times the rate they form in our own Milky Way. I have also attached an annotated image showing other galaxies in the wider field.

16 hour integration of the Heart Nebula with the Dwarf 3 telescope

The Heart Nebula can be a challenging object due to its low surface brightness, especially in my neighborhood where I image under Bortle 8/9...
