(the polarizers were not needed I just didn't bother to take it off.

Constellation - Ursa Major
Exp 11x720sec (12min) subs (2hr 12min total)
ISO 1600
Focus was soft. The seeing was poor and the tracking was problamatic, had to use 5sec integrations and that's a little too long for my setup. All the subs had a little trailing and could not use 4 of them.
