I hedged my bets and bought the iOptron Go2Nova GOTO kit as well as a Vixen Starbook S Goto system - the Vixen kit won me over.
So, I am selling the iOptron coversion kit. It is brand new, less than a week old, bought from TeleskopExpress in Germany. Complete set, and I will include the ST-4 autoguider adapter as well.
One caveat - I did modify the plastic casing at the back of the RA cover and filed a MINUTE amount of metal on the Dec support to fit my Vixen GPD2 mount. It now fits a GP, GPDX, GPD2 etc mount without issue. It fits the Skywatcher/Saxon EQ5 PERFECTLY.
The motors have optical encoders, so are reputedly very accurate. I ran them, and they are quiet enough, but perhaps a little noisier than the Skywatcher Synscan motors.
Comes with the entire package as shown in the links:

It comes with a 12V DC adapter, not shown in the links. Will need an Australian plug (just a travel adapter works, as this is what I tried)
I paid in total $480 with postage from Germany. I am selling it for
$350 including postage (weighs over 2kg all up).
OPEN TO OFFERS ALSO (trades or monetary offers)
