Astro-physics 7" f/9 used for all images unless otherwise noted.

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