Hi Stash, thanks for your response.
I was not aware of the PI Zero. You mean
, or the newer
Pi Zero W
? Please confirm.
I think the latter, as the former doesn't seem to have wifi (unless you added a USB adapter). Anyway, they both look very similar to my old 512MB model B: same memory, major "upgrade" seems to be only ~40% more clock on the still single-core CPU.
How relevant do you think was the added clock, ie perhaps the reason for slowing down was lack of memory causing swapping/paging?
From your report, I'm now converging to a scenario like the #3 you describe below (ie running only the absolute minimum device-control software on the Pi, and all the rest remotely, communicating with it via INDI). Glad to hear it worked OK for you -- in my case, I have a very reliable USB Wifi adapter (also bought on Adafruit, along with the Raspberry Pi) so perhaps it will work more stably -- but if not, I have ethernet also, so one way or the other, I think IP connectivity is guaranteed,
Thanks again. When I do the testing (still waiting for the mount and camera to become available, as they are now being used in another project), I will report back on how it went.
