The ASI120 does not work with Linux, this is known, as it is not supported anymore.... ?

Also in Astroberry you can start them fro the INdI control panel...on Astroberry desktop...

I have identified a couple of issues and changes needed to make things easier for testing/debugging and enhance functionality (you can follow development in the repo). In the meantime I am re-evaluating some of the assumptions around the needed functionality (especially for the presence of RTC since we will be having a GPS so...) but would like the input on those from as many possible users as possible.

If you can spare 2 minutes, you could help me by going to this survey link:

Thanks a lot in advance for everyone's input!

I really don’t see the difference between a set up profile or a set up imaging train... and maybe there are more important things to be moving forward with, rather that re inventing the wheel, at this point.... it seems that as soon as people get a good stable working system that they have learned to use, then it all changes... just my opinion :)

You say your rpi is connect to WiFi by both 2.4 and 5ghz at the same time, and that is impossible, it can only connect via one connection at a time, how can it possibly connect to both with just one internal WiFi card....??

I have that as well, and sometimes the Pi becomes unresponsive for 20 s or longer. After I disconnect the 2.4 GHz network, it is snappy, with almost no lag.
The same would happen when you connect via Ethernet, that might explain why you have these issues. Naturally, you would not see any of this when you control the Pi via keyboard and mouse.


I have the hotspot set to 5GHz, and connect to that from my PC...but my PC sees both 5ghz and 2.4ghz on my home WiFi network, but if hotspot is set to 5ghz, then that should be ok..??? Or not..??
with network cable it only sees 2.4 as the wifi network plug it connects to only has 2.4ghz, and laggy on them both...
So when you say you “disconnect the 2.4ghz” what do you mean turn it off in the router settings...?


When you look up your connection information, what are you seeing? Is your PC then connected to your Pi only (i.e. does it only have one IP address) or is it connected to your Pi with one IP address and to your home network with another? If you have multiple IP addresses on the same machine, it greatly slows down data transfer.
In my configuration, the Pi is connected to a WiFi extender, which then connects to my main WiFi router. So not on Hotspot mode. The Pi connects through both 5 GHz and 2.4 GHz to the extender. For reasons unknown to me, it will not connect if there is only a 5 GHz network available. So what I need to do is connect to the Pi via Remmina on the 2.4 GHz network, ensure that the 5 GHz network is present and connected, then disconnect the 2.4 GHz network in the Pi network manager. Now the Pi is running on 5 GHz only with a single IP address. My desktop is connected to the home WiFi router via Ethernet (old Cat5 cables that top out at ~ 10 MB/s transfer speed) and through another (!) router .

With that (definitely suboptimal) constellation, I experience almost no lagginess, certainly not more than 300 - 400 ms occasionally, barely perceptible, even though the entire traffic is routed through an extender and slow cables(!). But again, that is at 1920x1080 resolution. 4K resolution results may be different.

However, whenever I try to move data while the Pi4 is connected via both 2.4 and 5 GHz to my WiFi network, everything slows down dramatically. I suspect that you have something similar going on and that data are colliding on your network. I suggest making sure that there is only a single route that connects your Pi with your desktop.


Ok my OC is connected to my router via a network cable but not WiFi, and then my PC is connected to the rpi via the hotspot in 5ghz mode, so if I just disconnect my PC from the router, will that be correct to fit your recommendations and test....or do I need to do something on the rpi other than set the hotspot to 5ghz only..?.

Well, strictly speaking, flash is not just flash, the SSD would be much faster, but for purposes of just saving the images, a USB thumb drive will be more than adequate.. :)
I tried running my RPI4 from an SSD and from a USB 3 thumb drive, and the SSD is far faster, than the thumb drive, but the thumb drive only a little faster than the SD card...
