Okay, I just looked at the dried neg strip. Looks like I got something, exposure was based on the idea the moon is a sunlit object so I started at f5 and 1/500 for ISO 400 knowing that, a. A well worn Pen F shutter @ 1/500 is probably closer to 1/300
and, b. This film is carelessly stored and 9 years past exp. date.
Then, just started to stop down, 2 exposures at each stop.
HC-110 1:60 at 20C, go make oatmeal for the missus, sit down with coffee, finally remember film 20 minutes later. I'm easily distracted.
