Overview
The scope continues to limp along this month, and I have to go through the images manually and weed out the trailed ones after an imaging session. I have made arrangements with Dr. Clay Sherrod of Arkansas Sky Observatories to refurbish the scope sometime in the next month or so.
The SXV-H9 is the imaging camera, with exposures for variable stars of 120 seconds at 4x4 binning (unguided). This month's session notes are below the overview section.

This session was initiated remotely from Yarker, Ontario. I had left the dome open on Saturday morning and also left the lid off the scope. Using Windows Remote Desktop, I was able to run the show from away which was pretty cool! At the end of the session, I closed the dome since rain was forecast for Sunday afternoon.
