I can't laugh... Its like every time I am next to my telescope I get a case of the forgetfuls.... 24x600s exposures with the "Download subframe" checkbox selected. I ended up with 4 hours worth of 700x500px crops from the center of NGC253... Really pleasant.. Didn't even swear at the time... I was well controlled.. When it happened again the next night (only lost 1hrs data the next night before I got wise) I lost my mind and called myself a lot of colourful names!
