I thought the RPI4 would only be up to like 6-7 fps. I tried OACapture the best I can get is like 7fps.rbarberac post=61145 wrote: I've been using FireCapture 2.6 on Astroberry on a Raspberry Pi4 with great success. I've KStars/Ekos running in the background guiding the mount (running OnStep). My camera is ZWO ASI120MM-S running with USB3.0. Taking videos of Mars and Jupiter I was able to capture 70fps frames with a ROI of 400x400px. When I increase the frame size I must reduce the frame rate.
On this video you can see a screen recording from the vnc client running on on iPad connected via wifi Astroberry on RPI4
And the results
Achieving 70 fps is a great success!
Are you writing onto a SD card or a USB3 device?
Did you try to find out the bottleneck is at the camera transfer speed itself, or at the CPU/RAM/write speed of the SD Card?
Thank you!
