Northern Summer Skies

First light of my Sigma 40mm F1.4 DG HSM Art lens.
All the summer beauties of the northern hemisphere in one shot.
It is a phantastic lens. Unusual focal length, but stars only with tiny distortions in the corners at F1.4 !!! Did not stop down for test purposes and I was delighted to get this result. Much better than the 24mm lens of that series!
