Help with exposure settings

[wjschmitt]

I have indi-allsky running on a Pi5 and indiserver running on a Pi4 with ASI676MC. Plenty fast enough with lots of storage. I like to capture rocket launches occasionally, and my exposure/gain settings are optimized for slow-moving stars, usually max of 30, period of 15 and default is auto. So rocket captures are usually not ideal for a fast-moving object. Any suggestions for exposure settings for this case? Also, I guess I can set max exp to something like 1 sec for short periods of time. But is there a way to schedule these setting changes and revert back to normal after?
Thanks.

indi-allsky is not really designed for this use case. You could try setting the exposure and exposure period down to 1s, but there are limitations of the camera.

The limitations with individual exposures is it takes time to download the frame from the camera. Best case is 0.5s, worst case, 4s. The ASI676MC should be closer to the best case.

I sort of suspected this. I'll try a few things but I should probably find another program more suitable. Maybe though a 1s exposure will suffice. But is there a way to automatically change exposure settings, maybe with a script? Thanks anyway.

pyindi-client is quite flexible. It takes a bit to get used to because it operates asynchronously, but it works quite well.

Great. I'll take a look.
