350MM F5 in 2012

New build in 2012 (inspired by Ross Sackett). Although there are many problems with this build I have no regrets at doing it because of the convenience of quick and easy setup and lightness. Problems include; Image wobbles for 5 seconds in a moderate breeze and after focusing or moving scope ; Extraneous light reduces contrast of faint astronomical objects although some kind of light baffle could be rigged up (my next project) .
