Beginner's luck, but also frustrating: on the very first test picture a bright Perseid flew thru the field of view tonight, but it only left a feeble track, despite ISO 1600 and f/2.8: the wide-angle (25 mm equivalent; cropped here) apparently didn't allow the - fast, thru the zenith! - meteor to register much. Gotta think a bit more about better settings for tomorrow ...
