I imaged a 12.2 V Mag exoplanet transit  and used an exposure time of 2 minutes... the photometry software I was using indicated the the target was close to saturation and would not perform...calibration etc...Looks like 60 sec exposures at focal length 2000 mm at f8 will be adequate at 12.2 magnitude.  Full Well Depth of the camera is 51,000...using DSO..or first mode...
