Overview

I had my LX-200 supercharged this month. The scope was shipped on April 5th and arrived the next day at Dr. Clay's. Dr. Clay had the scope fixed up and shipped back, arriving in Ottawa on April 13th. I was able to complete a 5-night run before sending the scope away, and missed only one clear night while it was away!

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.
