Both nights dodging clouds before wiped out. (2) Purpose was to evaluate the 6 inch f/2.7 reflector for routine tracking. Looks promising but conditions so far too poor to form a real opinion, the last nights being plagued by bright moon, clouds, rather poor focus ( focus seems to change depending on telescope position so will have to install remote focus control.), and inability of camera to integrate properly with all the cloud passing over.
