Bode’s Galaxies
(Messier 81 + 82)
The sideways-on galaxy M82 to the top right of the frame, is emitting a huge surge of hydrogen deep into space, which could be due to the gravity from M81.
Total exposure 16hrs 45mins
Ha 66x300, Luminance 78x300, Red 20x300, Green 17x300, Blue 20x300
I used a cooled monochrome CCD camera and five filters to capture the light for Bode’s galaxies - red, green, blue, luminance and hydrogen-alpha. The resultant panels, which were combined to create the final picture, looked like this:
