Hello Ronald,
Formerly user of a DSLR tethered via a PiZW as wifi to usb bridge for qDSlsDashborad ran from a tablet. 1000 shots at 1/8000s lasted roughly 8s.
I then decided to decrease the weight and changed for a ZWO CCD to use with my Pi4B 8GB. Kstars was finally to be used, but since then I never could enjoy my new setup.
I spent (muuuuuuch) more time trying to figure out how to make it work correctly than having fun shooting nebulaes.
With this setup, 1000 shots at 1/32000s would last at least 2500s - yes, you did read correctly : 42 minutes !
After Jasem kindly explained that I had to set to distant instead of local, it would drop to 1200s - 20 minutes.
This is pure theorical, because I never (or very rarely) could take more than 60 to 90 pictures before it began lagging and hanging.
The SM OS together with the SM app did not make things go better.
I then bought a NVME SSD, an USB3 case and an USB3 powered USB hub, hoping this would solve the problem. Which unfortunately it did not.
I then lastly bought a Pi5, which I first thought was the solution. All the tests I did in taking up to 3600 shots at 0.2s were successful.
Unfortunately, there then were updates on both the SM OS and app, and things went bad again : lags and hangs.
I discovered too that every modification I did to the db, such as adding a lens, would make it stop working. And I had then to delete the db from the disk and recreate everything from scratch.
All those issues - except lags and hangs - are still present on my new config on the laptop running Ubuntu : 2+ seconds added to each take, malfunction after modifying setup and malfunction after updates.
Moreover, the indi config is (randomly ?) lost from a session to the other. So I keep a copy that I restore when that happens. This is the ZWO CCD ASI183MC_config.xml in the /.indi folder.
I must - and I will - take some time to list all this and open reports, trying to be as clear and exhaustive as possible.
BTW : I built following
the instructions
from Massimo's post.
