My other scope mounts are equatorials, so I’d rather not go through a meridian flip. It’s the guts of an old DS Meade, runs on 12V, and tracks I think well enough for radio. Next up is an Arduino wireless based unit to be able to rotate the Arrow circularly. But that shouldn’t be too hard-I’m having more trouble figuring out Fusion 360 to design the brackets. \n\nThanks for the advice.
