>>>>>I am just not sure how to get SGP to take exposures unless it is part of a sequence.
There are two ways to take exposures in SGP. YOu can use Frame and focus and save the pics. But that is a pain in the but.
:THe other is to take them in a sequence. When Stelios says he does not take them in a sequence, I think he means he does not just add flats to the target he is shooting. But, taking flats is still part of a sequence. Most people put them in a different target. YOu can make up a target to point straight up if you like. But why? Unless you have a robot to put the screen on the top of your tube, etc. you still have to disturb your sleep. That is why most people just have their rig point to a wall, where the program is made to point, turn on the flat panel, and proceed to take flats.
To mess with pre event actions, look to the first column of the sequencer. YOu will see an "X," a cog, up/down arrows, and a number. Click on the cog for any given row (the one with the flats in your case). Use the pull down menu to call "events" and take it from there.
