I've set up an Odroid C2 (a small ARM-based box akin to a Raspberry Pi but a bit more powerful) withEkos (part of Kstars) and all the cables needed to connect to a Meade Autostar and a Canon EOS 1000D. Amazingly enough almost everything worked first time. The RA and Dec motors whir when asked to and not otherwise; the camera shutter clicks when asked to, and so on. I'm very impressed.
The outstanding issue which I have been unable to solve as yet, is how to ensure that the images are downloaded to the Odroid rather than being stored on the SD in the camera. Curiously enough, a dark frame ended up in the Odroid's file system but, so far, no lights have appeared. A bunch of images are indeed on the camera's SD but I'd prefer not to have to remove it after each observing session.
This sounds like it should be a FAQ but searching the CN forums hasn't turned up anything.
Any suggestions gratefully received.
