Aperture Fever

I bought a Orion ST80 ~ 4 years ago and pretty much saw everything it could image over 2-3 years of observing. Last year I took one of John Dobsons mirror making classes and built a 10" f6.3 that I eventually converted into a truss configuration. This years project is a a lightweight 16" f5 (actually about f5.4) based on Kriege & Berry's book. Used one of Dan Cassaro's pre-generated 7/8" thick plain glass blanks. Last night had it out finally for some star testing. Happy to report no astigmatism, only the typical malidies of slight TDE and under correction. Plan to continue with star testing for a while before putting it up on a tester. Whenits ready to ship away for coating I'll finish the mount. I wonder what I'll do next year? Clear Skies,
