Description

Trying my hand at more galaxy targets. I pushed myself to learn more about LRGB-Ha integration and managed to get a fair amount of 10 min long shots of Ha to really get the starburst data. I think these are some of my favorite galaxies to date but I'm looking forward to learning more pre and post processing techniques on galaxies this year.

Thanks AstroBackyard for the details (https://astrobackyard.com/m81-and-m82-galaxies/ , also just noticed that Trevor's observatory may be in dedication to his black dog...sorry for unknownly copying the name):

The M81 and M82 galaxies are a pair of galaxies located in the constellation Ursa Major. M81 (Bode’s Galaxy) is a spiral galaxy that lies approximately 11.8 million light-years away, while M82 (The Cigar Galaxy) is an irregular galaxy at roughly the same distance away from Earth.These galaxies have a gravatational lock on each other and have affected the shape and composition of one another. Between M81 and M82, you’ll find the Integrated Flux Nebula, but this is extremely faint and difficult to photograph. Bode’s Galaxy and the Cigar Galaxy are members of the M81 Group of galaxies. 


M81 – Bode’s GalaxyAlso cataloged as NGC 3031, Bode’s Galaxy is a spiral galaxy about 10 degrees northwest of the star, Dubhe. Using a telescope with a large aperture, it is possible to reveal the spiral structure of M81 under dark skies.Bode’s Galaxy has a diameter of 90,000 light-years, which is about half of the size of our own Milky Way Galaxy. A supernova was detected in Messier 81 on March 28th, 1993. At the time of discovery, SN 1993J was the second brightest supernova observed in the 20th century.

M82 - Cigar GalaxyThe Cigar galaxy is an irregular galaxy (or starburst galaxy) that lies only 38 arc-minutes from M81 when viewed from Earth. This galaxy appears as a “rod of light” in modest telescopes, while larger telescopes will reveal the dark patches across the surface.The starburst activity in M82  is thought to have been triggered by interacting with M81 over millions of years. An interesting story about M82 is the unknown radio waves that were detected from this galaxy in 2010 by the Jodrell Bank Observatory.
