Bode’s Galaxies (M81 & M82)

Every year I try and do a better job of capturing and processing the Bubble Nebula in Cassiopeia. Here’s this year’s attempt. The Bubble Nebula is one of my favorite objects. Not only is it interesting scientifically (the bubble is the stellar wind of a hot O-type star blowing away the surrounding gases,) it’s also…

This pair of galaxies gets its name from their shapes. Both are viewed edge-on, and from this perspective we can see how a past interaction between the two warped them both. About 6 hours of exposure time from the backyard observatory.

Last weekend, I hosted an astrophotography workshop on lunar photography for our local astronomy club. Tonight the skies finally cleared, and I got to apply what was learned! Here’s our lunar neighbor, in hi-res glory.

M104 is known as the “Sombrero Galaxy” due to its visual appearance – but a deep, long-exposure image reveals its true structure. It’s a lenticular galaxy about 30 million light-years away, about 30% the size of our own Milky Way galaxy.

Seems I revisit this pair of galaxies, 12 million light-years distant, every year. Although they are close and bright as galaxies go, they are challenging targets for imaging – especially if you are trying to pull out the faint jets spewing out of the Cigar Galaxy on the right. This image represents over 25 hours…
