Description

Another session on the same trio, this time instead of using a 500 mm Rubinar reflector I am using a Canon 200mm L F/2.8 and a Kenko 2x extender. Tests on daylight landscapes showed better optical resolution of the Canon + 2x extender compared to the 500mm. 

Session consited of 85x60" but I had to remove arround 50% of the lights with stars not round enough (wind, tracking issues,...) keeping only 43 lights. 

Processing quite difficult because of qn irregular bqckground, maybe due to the close moon mqking reflexions, redoing flat 2 times trying to improve this did not do anything.
