Bought this Canon FD lens in the winter for photographing orions treasures (and othe widefield objects). Because my setup is running the whole night remotely controlled while sleeping I captured lot of images from M51 because no other interesting objects were visible..

Didn't checked the from february until yesterday and found out I had gathered a lot :).
Stacked with DSS and procesed with Photoshop. Hard to get good star colors.. detail of the DSO itself are personaly ok.

Total of 5 hours and 41 minutes of data.
All shot at F5.6 with canon 60DAW and Canon FD 200mm F2.8
