Flats are easy to do. There are a number of methods. I use an EL panel for convenience. They need to be taken each session with the same imaging train you took your light frames with. (i.e. same filters, same focus, same camera orientation). You'll have to work out the exposure time that works best with you scope/camera combo and experiment. The improvement flats do when calibrating raw files is well worth the effort.
