Hi Erik, I received my USB_focus v3 the other day and finally got it installed. A bit of stuffing around to get it to work and they didn't have a bracket for my focuser, but hopefully now it's sorted. What I have discovered is that I couldn't get it to work through my usb hub (Hitech astro mhp) and that I needed to run a separate usb all the way to my laptop. No biggie as my laptop sits beside it but a consideration to think about.
Good on you for getting SGP as well
Chris
