Beating light pollution with a new synthetic RGB algorithm
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…
Sombrero Galaxy
M104 is known as the “Sombrero Galaxy” due to its visual appearance – but a deep, long-exposure image reveals its true structure. It’s a lenticular galaxy about 30 million light-years away, about 30% the size of our own Milky Way galaxy.
The “Outer Limits” Galaxy
This one’s also known as the “Silver Sliver” Galaxy, or more formally NGC 891. It’s about 30 million light-years away, well beyond our own local group. It’s thought to be quite similar to our own Milky Way! What I really geek out on, though, is the wider views here – there are so many other…
The Horsehead and the Flame
I trained my telescope at this pair of nebulas in Orion for a total of 10 hours. On the right is the iconic Horsehead nebula – actually a dark cloud of gas in front of the illuminated nebula behind it. To the left is the Flame Nebula. In between, in the upper-left, is the bright…
The Bubble Nebula, take… whatever
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…
Off to See the Wizard (again)
These past couple of nights, I revisited the Wizard Nebula – home of a star cluster about 7,000 light-years away within the constellation Cepheus. This is a false-color image in the “Hubble Palette” where red, green, and blue represent ionized Sulphur, Hydrogen, and Oxygen emissions respectively. Can you see the “wizard”? Hint: he’s lying on…
