My mount is a custom modified EQ-2. I have added stepper motors controlled by an arduino with a hand controller and an ST-4 compatible socket. It gives a nice smooth movement but I would like to add guiding to it now.

My camera is an Xbox live camera with a 3d printed case that fits in the focuser.

Telescope is a Celestron eq130.

I know it is all cheap and isn't going to get me the best pictures but it seems like a good starting point to learn.

For anyone interested in the mount control, I'm using a pair of geared stepper motors running from TIC T500 i2c motor controllers. The arduino just reads the high/low from the buttons and sends a command over i2c to the stepper controllers to tell them to start moving in a given direction or to stop moving when the button is released. The ST-4 socket is the wired in to the buttons via an opto-isolator.
