First light for an old glass lens from the 80's. Also testing the new Astronomik CLS for the Eos M.

----

To the right center, close to the border , there is a dark spot. I lays between the blue double star HIP 4155 and Achird (not visible here). I could not find the name of it. It isn't LBN 611. Anybody has a clue ?
