the way you figure out the flats is to use the flat wizard to compute the duration of the flats based on the brightness of your flat panel (or laptop screen or pad or whatever you are using - panel flats mean any artificial light source was used for the flats, vs. sky flatss or t-shirt flats which all use the sun as a source of illumination)
