This is NGC281, or the “Pac-Man” nebula. I think it’s one of those objects that might look a little like its name if you’re viewing it through a big telescope in a dark sky, but takes on a totally different character in long-exposure, narrowband images such as this. This is a total of 13 hours…

It’s really just a small portion of the Heart Nebula… that kinda looks like a fish. Maybe not the prettiest object in the cosmos, but it reflects a few technical accomplishments for me. About 20 hours of exposure time in total on this. Below I’m presenting it in a false-color “Hubble Palette”, as well as…

This is the Tulip Nebula in Cygnus, but see that shell-like structure just above it, to the right a little? That’s the bow shock wave of Cygnus X-1, a stellar-mass black hole! It’s one of the most powerful X-ray sources in the sky – but don’t worry, our atmosphere protects you from it. 20 hours…

I don’t know why the press has latched onto the name “the green comet” for C/2022 E3 (ZTF) – most comets are green, and it’s too dim to see any color at all if you’re viewing it through binoculars or a telescope. But through 2 hours of total exposure time, the colors do emerge, and…

The “Jellyfish Nebula” is a supernova remnant in the constellation Gemini, about 5,000 light-years away. It’s the gas blown off from a star that exploded, sometime between 3,000 and 30,000 years ago – we’re really not sure when it happened. But it makes for quite a spectacle! I was plagued with technical issues while capturing…

Had a few hours of clear skies last night, and captured a globular cluster I hadn’t imaged before: M92. It’s a pretty one, and I’m surprised it’s not more popular. It’s in the constellation Hercules, and I suspect it just gets overshadowed by its even more spectacular neighbor, M13. Globular clusters were enshrouded in mystery…
