Mounting and drive corrector

Mounting was custom built by Edward Byers with a 11 5/16" RA gear and a tangent arm for declination. Drive corrector is a microprocessor controlled unit of my own design and construction. The drive system frequently exhibits less than 2 arc-secs of periodic error for exposures of up to 60 minutes.

Image processing

Processing was done with SBIG's CCDOPS and mosaic combining and unsharp masking was done with Adobe Photo-Shop.
