Description

This is a first light of sorts, maybe more like a field test of some duration. Taken during UK's "bright time", that is the time of the year when there is no astronomical night and all you have is nautical twilight of 2-3 hours in length. As most field tests of newly acquired hardware this one was also beset with various issues, most notably not having tighten enough the screws securing the mirror cell to the tube, which resulted in notable defocusing and tilt. On balance I'm quite satified with the results and the promises they hold for the future.
