Full Version: Alt-Az accuracy with HP 35S

We have had clear skies in S. Calif the past week allowing me to check out the accuracy of the alt az pgm posted a few weeks ago. The pgm delivers +- 1.5 degree theoretical accuracy with many objects less than one degree. This means if the scope is level [ a simple bubble level wii suffice ] and the az and alt circles well laid out, most objects should fall in or just outside the field of view of a wide fied eyepiece.This is exactly what happened using my 5" f5 refractor mounted on a simple wood fork mount. Objects were checked on both sides of the meridian at various altitudes. Regards, Howard
