NGC253 is most commonly known as the “Sculptor Galaxy,” because it’s found within the constellation Sculptor. You probably haven’t heard of Sculptor – that’s because it is considered a Southern-hemisphere constellation, and it’s only visible in the US from Southern states such as Florida. It’s also known as the “Silver Coin Galaxy.” It’s part of…

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…

Last night I set out to image Jupiter and Saturn, but both are pretty far away at this point, and the atmospheric conditions weren’t great. So I tried for the Moon instead. We take our nearest celestial neighbor for granted – there’s a whole world right next to us, waiting for us to explore it!…

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…

Imaging deep sky objects from a suburban driveway forces one to find ways to deal with light pollution. Light pollution is the enemy of astronomers – but in reality, there are ways around it. Some of the most beautiful objects in the cosmos are called emission nebula. They are clouds of gas, often where new…

M17 is commonly known as the Swan Nebula or the Omega Nebula. From this angle, I think it looks more like a crab – but “Crab Nebula” was taken! Shot over a hazy summer night, with narrowband filters for the gases of the nebula itself, and RGB natural-color filters for the stars. Presented processed with…
