thanks Jase,
you can only do so much with single (uncalibrated?) subs but it was a good experience getting some data without having to do battle with my equipment in the back yard.

for what it is GRAS13 works well, mabee not so good on fainter targets as you only get a low res jpeg sent to you that wouldn't be that great for stacking but it seems to do ok on the brighter subjects

edit: Jase, i checked for the calibration files but couldn't find any for G13 since its new and still in testing i guess.
