webcam for telrad?

Posted By Dave Erickson

Very good thought. I think I'll give it a try, and add a wide field camera to verify position prior to platesolving. For now I have written code to park and un park an old AP1200 driven with an FS2 at my fledgling site.

1.25" Ronchi tester -- the EASY-tester

Posted By Dave Erickson

I have not tried this product but have used the Ronchi test. I am sure you know that its a well documented test method; see Star Testing Astronomical Telescopes Suiter and the ATM book books 1 and 2 for details. Works well but not as fool proof as the add implies.
