Markarian’s Chain

As we enter summer and the Earth starts pointing us back into the plane of the Milky Way and its many nebulas, we’re nearing the end of globular cluster season. M5 seems a fitting one to end on this year; there’s nothing terribly remarkable about it, other than I think it’s pretty. It’s located about…

11 light years away, the “bubble” itself is formed from the solar wind of the large, hot star inside of it. Imaged with narrowband filters.

Here’s IC417, commonly known as the “Spider Nebula.” Just outside of the frame is a smaller one called the “Fly Nebula,” but my field of view isn’t quite big enough to capture them together! It’s about 10,000 light-years away, in the constellation Auriga. Imaged over 15 hours; narrowband nebula blended with RGB stars.

Another revisit of an old target, with better gear and better conditions. This is the Pelican Nebula in the constellation Cygnus. Shot in narrowband over one night, and presented in the “Hubble palette”. Two takes – one wider field, and one close-up with the stars removed. In both cases the image is rotated and mirrored…

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.
