And the imaging choo-choo. An ASI1600MM Pro with ZWO EFW, and Stellarvue .8x FF/FR. The FF/FR is held in place in a 2" eyepiece holder. I actually get less tilt using that than the rotator they sell, which allows you to screw the FF/FR into the focuser. Grrr. Oh well. This setup works well enough.
I access the Raspberry Pi via WiFi. Those of you that are Pi-savvy may be wondering why the USB WiFi adapter when the Pi has built-in WiFi? Two reasons, actually. Reason one, the built-in has a terrible antenna, and therefor terrible range. Reason two, now that I have two WiFi adapters, I set it up so the built-in is a hotspot, and the second connects to my home WiFi. So when I'm at home, it automatically connects to my home WiFi, and I can access it from my computers indoors no problem. But if the home WiFi is nowhere to be found, then the built-in hotspot lets me connect my laptop to it via WiFi quite easily. The limited range of the internal WiFi is fine when using it as a hotspot, since in that case I'll be very close to the scope anyway.
I have only a single cable hanging off the scope, a power cable (can't avoid that). When at home, I just plug it into the AC adapter you see. If I were to take this on the road, I could plug it into a battery.
My next project is adding autofocus. I have the stepper motor, the Pi has the stepper controller. I have a 3D printer for the bracket to hold the stepper onto the focuser. I'll post some pictures when I get that done.
