Last night I was all setup to capture a transit of the ISS before the full moon.
2:24 AM and everything is good to go.
I am running an ASI183 mono from a scope-mounted headless miniPC. I use my laptop with Microsoft Remote Desktop to control/ the miniPC. The camera is plugged in directly into the PC's USB 3 port of the miniPC.
Fircap is reporting a capture fps of 18 occasionally dropping to 10. The recording fps is 6 or 7 . I immediately noticed that because of the recording lag I am dropping frames in the recording but not in the capturing. I keep going. I had previously played with USB rate from 40 to 100 and it appeared that 100 was the best based on capture fps. I also have ticked "High speed." On the screen I see the transit and I am so happy! I stop the capture. The recording finishes some 30 seconds behind. I noticed that I only recorded some 400 frames during the 3+ minutes of capture. Odd. When I get home and look at the video there are only 24 seconds recorded at reportedly 19 fps (which is the max for this camera) but there is no ISS. Just a nice full moon.
The actual recording fps was 2. I missed the 1+ second transit even though everything else location, time, etc was right. Very frustrating.
Any one has some suggestions to maximize the recording fps with Firecap?
