Hello all,
I'm currently running Astroberry on a RPi4 - Star Adventurer 2i / Redcat51 / Sony A7iii / ZWO120MM - guiding through PHD2 and capturing via KStars / EKOS. I'm looking at getting a dedicated camera and specifically the Altair 26C. Looking through the support for the INDI library I see that the Altair cameras are all supported but that there maybe an issue using the RPi4 with the USB transfer speed(?). I see that the 26C has 512Mb of DDR so Is this something that I should be too concerned about? Interested to get some opinions before pulling the trigger!
Thanks in advance..

Hi. I use astroberry with a RPI4. I use the altair GPCAM3 178M as a guiding camera and I use the altair hypercam 269c for imaging. I've had no issues with the 269c for imaging, although I do have a recurring "exposure timeout" with the 178M which gets in the way occasionally. This i believe is due to a USB bandwidth issue which is mentioned on the indi altair page. The problem is mostly fixed by binning my guidecam.

Many thanks Dave,
Good to know that you have it working OK.
I was in touch with Altair and they had also mentioned that the RPi4 might not have enough processing power / USB power to run the 26C reliably. At present I have an M.2 Argon case (250GB M.2 SSD) connected to the guide camera and Sony A7iii directly and then wifi-d out to a MacBook via astroberry.local. All images are stored only on the Sony SD card at present.
I didn't want to get the camera and then find the RPi4 wasn't up to the job, especially the image storage.
