I couldn't upload the original .xls file, so here's a 2-page PDF.
Essentially I wanted a piece of paper I could write on as I took images through the night, so that I could keep track, from frame to frame, of what camera, lens, etc I was using. As my older lenses don't let the camera generate meaningful EXIF data, I was getting lost and forgetting what lens and f-stop was being used to take any particular image. I wanted to be able to name my selection of equipment once only, and then refer to it as I go through the night by a given session reference number. Not being an expert at this, but I'll do one for webcam/CCD later too.
