Test of 135mm lens on M13

M13 is the object I put a red mark above. The camera was piggybacked to my scope which was tracking but not autoguiding. The lens is an old 135mm f2 ais Nikkor.
This is a single 5 second exposure at ISO6400 and f2.

Nikon NIKON D750,135mm f2 Nikkor
5s f/2.0 at 135.0mm iso6400 full exif

other sizes: small medium large original auto
