first light of the Samyang 135mm at open f/2 - it is sharp to the edge of the fullframe Eos6da. Like a mini Hyperstar, but without tilt problem :-)
I shoot the RAWs - 2min Subs at Iso400 - on two locations actually, at SQM19.9 and 20.8 - here is a comparison, and surprisingly the difference is not as big as I expected, when the RAWs are stretched to equal lightness:

Objects abound in the picture, from famous to infamous. For the latter note the tiny blip of Sh2-106 the little hourglass nebuls in Cygnus. You know where to look for? Also I identified 4 reflection nebulae. Hope you have fun exploring them!
