It happens to be the only thing visible from my apartment balcony observatory so its all I have data for yet. M81 is also next to it and i might try that tonight.
M82 google docs fits zip
Approximately 40 minutes on M82:
Celestron Omni 102 (non-ED version), F10
Celestron 102mm spotter as guider, f/5
on Meade LXD75
I'll take pics of the setup tonight
