EQ5 single axis autoguiding

[Deathbat219]

Hi.

I have a Bresser EXOS-2 (EQ5) mount with single axis motor (RA) and an 8 inch newtonian scope. Currently I can take ~30s exposures without trailing. The mount doesn't have a guiding port so I would like to modify the motor hand controller to be able to connect it to my laptop.

I found a tutorial on how to modify the dual axis controller but the single axis controller is built differently and I don't know where to solder the wires ;)

The tutorial: http://astrocasto.blogspot.com/2012/02/how-to-set-up-guiding-system-for-your.html
This is the controller I have: https://www.rothervalleyoptics.co.uk/skywatcher-ra-motor-drive-for-eq5-with-multi-speed-handset.html

How should I solder the wires? Is it even possible or should I buy a dual axis motors set?

I would be interested in seeing how you get on with this myself as I have the same mount and the 2 motors for RA ans Dec

The concept for modifying the handset is that you attach a wire carrying the guide commands to a left and to a right slew button contact.

So you only need to identify the correct contact with a test meter, the rest of the mod should be as in the Dual Axis mod.

So it doesn't matter that the only speed is 8x? Will PHD be able to guide with that speed?

Your link was to a Multispeed Handset, so I assumed low speeds were available.

8X might work, but I'd suggest starting with the lowest setting and find one that gives 12 to 15 steps in the calibration.
