Marcel,

I'm trying to keep to simple hand held methods. The best way would be a motorized tripod set to latitude that has the camera shutter held open. This would provide flexibility for ISO and f stop settings. No room or money for smart tripod gear though. I'm satisfied with the hand held lunar camera trial results so far and will be trying for a full lunar calibration series using the 50 mm lens.

Greg,

Regarding

Calibrating the camera using low magnitude stars isn't going to work since the star images are fat and not symmetrical.

Looking at your image suggests that by using a tripod and a slightly faster shutter speed you should obtain star images which should be useful for calibration.
