The Pinwheel Galaxy

Johan Bode discovered both Bode’s Galaxy (M81, on the left) and the Cigar Galaxy (M82, on the right.) Look closely and you’ll see many other, more distant galaxies in the background as well.

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…

Formally Abell 33 or the even more catchy name PK238+34.1, the “diamond ring nebula” is a planetary nebula – that means it’s the gas blown off by a dying star, not too different from our own sun. This one’s interesting due to its almost perfectly spherical shape, its cyan color from ionized Oxygen gas, and…

Last night was hazy, cloudy, and with an almost-full moon that would wash out anything else I could try to image. So, I imaged the Moon itself. Tried out some new techniques; usually you would use a specialized telescope with a specialized camera and specialized software for shooting the Moon, but I wanted to see…

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…

This is a weird little cluster of galaxies – there are four in all, and each one is completely different. There’s a weird, S-shaped one that must have been messed up by its neighbors in the past, a somewhat normal-looking spiral galaxy, and elliptical, and another one that’s viewed edge-on. Galaxies that have interacted with…
