Thor’s Helmet
An interesting emission nebula 30 light years across. Imaged with narrowband filters.
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…
Triangulum Galaxy
Part of our Local Group of galaxies, the Triangulum Galaxy (M33) is about 3 million light years away and the most distant object visible to the naked eye under dark skies.
Revisiting the Crescent Nebula
I’ve imaged this one before, but for whatever reason I picked up way more detail on it last night. Part of it’s a better camera and better tracking on the telescope mount, but I think conditions may have just been really awesome last night. It’s not normal to have this many good nights for astrophotography…
Back to the Bubble Nebula
The Bubble Nebula still has a soft spot in my heart… it’s what really got me going with astro-imaging years ago. It’s just such a fascinating, gorgeous object and it really inspired me the first time I saw it. Here’s my deepest exposure of it yet: over 20 hours of exposure time, in the “Hubble…
Globular Cluster M15
Located about 33,600 light-years away within the constellation Pegasus, Messier 15 is a globular cluster – a tight, ancient ball of stars on the outskirts of our galaxy. The Milky Way is surrounded by many such clusters; this one’s special because it’s known to host a rare intermediate-sized black hole at its center, and it…
