My astro mount is beside my garage with a PC just inside to control it. I can control the mount and cameras remotely from my home study using Google Remote Desktop – but not my Orion AccuFocus focusers.<\/p>\n\n\n\n

I read a forum post (that I can’t now find) which explained how to control the focuser over USB. I adapted it slightly to avoid the need for stripping one end of the focuser cable by adding an RJ10 socket.<\/p>\n\n\n\n

Component links: USB Relay<\/a> – RJ10 Socket<\/a> <\/p>\n\n\n\n

The wiring diagram I used is here<\/a>. Note that the wires to the socket are soldered to the left and right pair of pins respectively.<\/p>\n\n\n\n

To control it, I modded an app I found on the net to give me a selection of timed pulses in both directions. This gives fantastic control for fine focussing.<\/p>\n\n\n\n

The whole thing cost less than \u00a310 but means I can now control everything from the comfort of home – or even further afield.<\/p>\n","protected":false},"excerpt":{"rendered":"
