Sadly I think you are right. I'd found some information about firmware, though it was upgrade rather than downgrade. It is the older USB2 camera and I tried the Zwo firmware tool, but no difference.

To rule out the Pi or Astroberry, I tried it on my linux laptop and it also failed (including with the FireCapture 2.7beta which has better Zwo support). It looks like I'm not going to be able to leave the world of Windows until I invest in a new camera Even the updated model will be cheaper than a Windows laptop so hopefully Astroberry is still a way forward.

Looking at the ASIair Pro from Zwo, gives a pretty conslusive answer:

My camera is the only one of their range that is not supported. The ASI224MC is looking very tempting now!

Dave,

before you make decisions read this: www.indilib.org/forum/astroberry/8142-as...n-rasperry-pi-4.html

The ZWO SDK on Linux is just terrible on Linux systems. Only reason I still use Windows for planetary and solar. Deep Sky and ZWO normally works as good as you can expect, but video can't keep up with W10. (Purely because of ZWO's crap Linux SDK. In their ASICAP software for Linux the USB bandwith is set to 40 (seems can't change) which results in low framerates and still problems.
ASIAIR not much more than a RPI4 in disguise with some power additions (and i suppose a lot of Indi work on it)

Hi,

Thanks for the tip off about that. I assumed the ZWO cameras would work well with linux and the Pi 4, because as you say the ASIAIR is a rather expensive way to buy a Pi. It seems odd that they don't have good driver support for essentially their own product. There does not seem to be many comparable cameras in the price range as the ZWO options. It now gives me 3 options:
- Get a new ZWO camera and hope they address their driver issues
- Look at getting a cheap laptop that can run Windows 10, though those similar in price to a camera (£200-£250) have low memory and 64Gb eMMC memory as storage. (my old laptop was a netbook for £150, but tablets killed off that market)
- Getting a ZWO camera and join in with the dev efforts on a driver. I've got a lot of linux experience and development skills, though never touched video drivers before.

Dçn't know what your main target is. If it is deep-sky (single frame capture) then there is no problem. (Except that sometimes when I use 2 zwo cams thru indi, guiding and capturing, there can be some hangs with the camera) If you go planetary, that's another story. But when using ROI and not the full frame, cameras seem to get their speed. Can't speak for the RPI since I do most solar, and then I need the max frame and highest frame rate possible. Could not do that with the 178 on both an Intel 4790k or AMD Ryzen (4core) with Linux. (With Windows on these machines no problem). The ASI120MM-S (USB3) has smaller sensor, so less Mbytes and works better under Linux. So probably sensor resolution (Mb) is making things go bad beyond a certain point.

Let me know what do you see when you type in " Sudo rpi-eeprom-update " in terminal?

@PDB, I'm mostly doing solar system imaging. My scope is a Celestron NexStar 90SLT, so at 90mm on an altz, I'm not going to be doing much in the way of DSO. I'm interested to see what I can get from it, but I'm not holding high hopes.

@TomAstro, I get

FYI, the ASI120MC USB 2 version DOES NOT work properly at all on INdI, even with the ASI firmware update, as has been said it’s not even supported anymore by ASI. Some people have managed to hack together something that works, but you really need to know what you are doing, and even then I am not sure how consistent it really is....

Cheers. I think now it is down to new camera or new laptop. I'd prefer a new camera and run astroberry off a Pi, but I'm struggling to find a good model at a good price that would work with the Pi. The ASI224MC at £219 (UK) was looking good until I found the issues people had been having on anything other than Windows

I can recommend the ASI120MC-S or MM-S. Both are USB3 cameras and work very well. I have been using several of them on different setups for over 3 years now and haven’t had any issues at all.

Now I see why your ASI120MC having an issue. Please read this post, indilib.org/forum/general/7656-solution-...era-and-usb-hub.html

I am using ASI120MC til now without any issue. Good luck
