Description

A lot of firsts for me:

New mount (iOptron Hem 27), new lens (a second hand Sigma Art 135mm lens - used at f /2.2), a new autofocuser (Astromechanics). All of which I had had for a while but came together during a holiday to Crete. Measured SQM was an average of 20.8 over several nights.

During post processing I used BlurXterminator, StarXterminator and NoiseXterminator. The stars where quite good out of camera. BlurXterminator corrected whatever was left of deformations in the far corners.
