Results from my video observation
I taped this video on my Sony TRV240E
camcorder, that has a 'video in' function. The film was later imported to
the PC using Pinnacle Studio and with the help of VirtualDub I was able to
load the avi-file into
Limovie. I measured all frames manually, what
turned out to be a hell of a job. But it was well worth the effort as you can see below.
Gerritsen combined all observations to make this reduction. The straight
lines show how each observer saw Regulus moving along the Moon's valleys and
hills. A very nice result indeed.
