i'm just getting into astronomy again and have a Skywatcher Evostar ED80 with Skywatcher Evoguide ED50 (on HEQ5 mount) and a ZWO 120MM CCD to use for guiding.
I am using a Raspberry Pi 3B as the 'remote' controller for this set up. I have used the rlancaste script to set up AstroPi3 and it all seems to work with the exception of the CCD. Using PHD2 directly on the Pi I can connect to mount and guider and can control the scope position with KStars without any problem I am wanting to use PHD2 for guiding. Without Kstars running I start up PHD2 on the Pi and get the first light start up process. I select the camera, it asks if it is connected (it is) and it gets the pixel size automatically. I continue and select On-Camera for the connection (using ST4 port on camera connected to HEQ5). I continue not selecting Aux Mount or Ao and it prompts for a profile name - I give it one and allow it to do a dark frame library. It tells me there is no compatible dark frame library and I press start to generate one, I cover the CCD/guide scope and continue. A very short while later the PHD2 screen disappears and that is it.
The 120MM works when connected to a Windows system.
Can anyone point me in the right direction to get beyond this point please?
