This is another pending subject, much more, after the disaster of mi hard drive wich contain all my astrophotos.
This is the first job with my invention, Celestron C8 (8") in a Meade LX9012" fork Mount.
Prime focus with focal reducer, I believe that not bad considering my suburban sky and bad seeing.
After many days with very bad conditions, yesterday I has had a few hours of clean sky and low humidity, enough for shot to M1 before dawn behind the horizon.
