Bode’s and Cigar Galaxies (M81 and 82)


bode

This pair of galaxies is a popular target for astronomers. Located in Ursa Major (the Big Dipper) and each about 12 million light years from Earth, the Cigar Galaxy is on the left and Bode’s on the right.

This exposure includes hydrogen-alpha data, which produces the red “wings” on the Cigar and spots in Bode’s. This red portion is not visible to human observers, so the cigar shape is more apparent visually.

 Scope: AT111EDT at f/5.6
Mount: AP Mach1GTO
Camera: QSI 583 at –15C
Exposure: (about 3 hours total)


About Greg Marshall

I am a retired electronics engineer and after a few months of enjoying my leisure I began to miss doing product development. My astronomy hobby always needed new solutions to unique problems, so I decided that whenever I came up with a good solution I would try to make it available to others.
