Really nice set-up now Dan.... Must admit that I have not touched or looked at the collimation, except for star tests, and it appears to be fine, but as you say....I probably do not know what 'fine' should look like. Might be good to meet up at some point, and bring the 800 over.... I did go out last night, but clouds rolled over and that was it! and started to dew up....really low dew point last night so it would appear. I just have the ordinary shield, not the heated one....would be nice to have some power at some point as well! still don't really know whether the mount works or not!
