Paul I hate to tell you this but the focuser on the 100ED is an Astro Physics focuser and it does not move with a 50g Lodestar.
Please read what I posted it was a 90mm MAK mounted on the RH200.
Only someone who is delusional would think that the stars recorded by a F3 optic are as perfect in the centre as the corners of a state of the art large sensor camera.
Advice is always gratefully received. It does help if it is well thought through.
