Tŷ Du Observatory

Another clear night, and it looks like there’ll be a few more over the weekend.

I spent some time playing with PemPro and PERecorder to see if I could make a PEC curve for the mount. It looks like each worm cycle has a different profile so I’m not sure how much help it would be. After spending several hours using the webcam to record PE I decided enough was enough and moved on to imaging with the Atik 16ic.

I didn’t get much, it was already late so really it was just a test of the PEC experiment.

M15 - Globular Cluster

M27 - The Dumbbell Nebula

M57 - The Ring Nebula

Even after applying PEC I was still unable to manage more than about 30 seconds per frame.
