It was shipped on 30/3/19 to Australia and received a week or so later. Description Unit price Qty Amount USB Gu...

Connecting GPUSB to Losmandy G9 Mount

Hi, I have just purchased a GPUSB guide adapter and cable for my non-Gemini Losmandy G9 mount (made for Celestron). When I plugged it in there was a short circuit which blew up a diode (reverse polarity protection) in the Celestron Digital Drive System Model 492. I have replaced the diode and the 49...
