I'm testing Pixinsight on a 45 day free trial (loving it!). I use a William Optics Z73 with a 533MC Pro on an HEQ5 Pro mount with guiding and controlled via ASIair Plus. For each target/session I take lights, flats & dark flats. I have a separate recently made library for darks as described by others on SGL. I have sorted my file storage again as per great advice found on here.
My question is that when I stack a target with WBPP and then continue to process the image, I'm left with what I think are a load of files I won't necessarily need to keep in the future, should I return to the target to gain more data.
Would anybody be able to offer any advice?
