Gregorian Telescope results

On Oct 27, 2012 the Gregorian saw its' first light. Rough collimation was done during daytime, by centering the secondary reflection in the primary, and then centering the primary in the secondary. Fine collimation is a matter of minimizing coma at the eyepiece, by adjusting the primary.



At first light there appear to quite some reflections, especially from the inside of the baffle tube. A photo of the moon shows however that contrast is quite good nevertheless.
