Re: ATM 14.5 i.s. couder results...startest

You have the same problem with a "real" telescope when collimating.  
Collimate in small increments, and after each adjustment re-center the star. 
  I don't think you can use our star (the sun) to star test or collimate.  
Too much energy, and too large a disk.  Try Polaris.
