This is a very bright star, short event, and I drove Kirk to south of Watsonville and Jensen Rd. He set up on Jensen Rd and I set up a half mile further south. We had traffic trouble and didn't get to our site until just a half hour to go. After setting out Kirk, then driving to a site I could use despite the wind and a very bright light in the direction of the target, and setting up; I did not have enough time to get on target and got no data. Kirk did get a short positive
I got a 0.6 sec event for 2000 FH3, at 1x, gain of 34, from Jensen road. There was significant wind shake in the recording, so I used dynamic apertures. Fortunately at 1x there was another star visible for tracking and reference. I first used the default setting for the apertures, which was a threshold of 10. It tracked well and never lost the target, but there was a lot of noise and waviness due to the shake, and I thought I would have to trim the shake out in pymovie. But then I tried a nest of 6 dynamic apertures, and found when I used a threshold of only 2, it still tracked well and that the noise and waviness was much reduced, so I didn't have to trim it. Remaining waviness due to shake or thin cloud was reduced by smoothing on a tracking star. The dynamic aperture only used a default static mask during the event. So next time with wind shake I'll know to try a reduced threshold.
