Astrophotography has a lot of legends and rumors floating around as regards focal length of scope. Since the focal length of the scope, size of the CCD, weight of the rig, and […]

Not getting a lot of stars in before The Blessed Event
I am ashamed to admit that I’ve more or less given up on astrophotography this month. The spring galaxies are getting away from me again, and I hate to think about a […]

MPCC and coma correction
The MPCC is up there with the ST-4 as one of my Best. Astronomy. Purchases. Ever. My 8” f/5 Newt was almost worthless for DSLR photography before I added the MPCC. Now, […]

M42 is a great tester object
M42 is a great “tester” object. It’s big, bright, has an easy to find star pattern surrounding it, and can even be seen in the viewfinder of the camera. So I end […]

M27, The Dumbbell Nebula in Vulpecula
I’m having trouble getting the G11/SCT combo to work shooting to the East, for some reason. So, I decided to “make lemonade” and shoot to the West instead. This neatly avoids the […]
