Thor’s Helmet
This week’s target was Thor’s Helmet (NGC 2359), an emission nebula in Canis Major a rather distant 12,000 light-years away. It’s formed by a Wolf-Rayet star in its center, which is a crazy-hot star whose immense stellar wind is bunching up and ionizing the gases around it in these complex patterns. It’ll probably go supernova…

The Sculptor Galaxy
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…

The Rosette Nebula, revisited
Had a couple of clear nights recently, and trained the ‘scope at the Rosette Nebula again. By combining this year’s data with last year’s, I created an image with a total 27 hours of exposure time! The Rosette Nebula is about 5,000 light-years away within the constellation Monoceros, and is the birthplace of the cluster…

Looking back to the age of dinosaurs (NGC2336 and IC467)
Spent a couple of nights imaging these distant galaxies; the spiral in the upper-left is NGC2336, and the other is IC467. Galaxies this faint and distant generally don’t have catchy names! NGC2336 is 100 million light-years away. Think about that – you’re looking 100 million years in the past. The light we captured started its…

The sun is feisty lately.
This solar cycle has been quite a bit more active than forecast. It motivated me to up my game a little bit with solar imaging; this is my first image with a “double stack” setup that results in narrower filtering on the Hydrogen-alpha emissions from the sun. Lots and lots of prominences, filaments, and sunspots…

The Dumbbell Nebula
The Dumbbell Nebula (M27) is what’s called a planetary nebula – but it has nothing to do with a planet. This shell of gas was blown out by a dying star; once it started to run out of Hydrogen to burn, it expanded and blew out the gases you see here. The star then collapsed…
