Cone Nebula

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.

This was intended to just be an image of the galaxy M77 in Cetus, but quite a few other galactic photobombers showed up! The annotated image below guides you to the brighter galaxies in this image, but click on it to expand it, and you’ll find many other ones as well that are incomprehensibly distant.

The Rosette Nebula is about 5,000 light-years away in the constellation Monoceros. It’s the birthplace of the cluster of stars it contains. While it doesn’t look much like a Rose in this view, the false-color narrowband image below brings out more of its structure. 7 1/2 hours of total exposure time, on New Year’s Eve…

Globular clusters are mysterious objects – they are dense clusters of stars, some containing hundreds of thousands of them. And they’re not within the plane of the Milky Way galaxy; they are scattered around it. How they formed is a bit of a mystery. Did they form with our galaxy, or are they the cores…

If you’re a fellow amateur astronomer, you might be curious as to how our “live star parties” on our Boldly Going YouTube Channel are produced. The more people doing this, the better! Here’s how it all works behind the scenes, which might give you some ideas on how to produce your own show. The Heart…

In these short summer nights, I want to take advantage of every moment of darkness. Right now, the galaxy M100 is up in the hours before midnight, and the “Tulip Nebula” – formally SH2-101 – rises just as M100 sets. So for this past week, I’ve been imaging both objects. But no more clear skies…
