Hi Folks, I've been trying to retrofit a homemade declination motor unit onto my old C8 Basic (the base model, no PEC, no AstroMaster; Dec motor is supposed to run from a 3.5mm phone jack).
I finally found a motor that runs smoothly both at the slow and the fast slew rate voltages (which one accesses by either just pushing the button, or pushing the button and then also pushing the opposite direction button, respectively).
Does anyone know what Dec knob RPMs these two rates are supposed to produce? I did some searching already and found the following relevant threads:
However these threads seem to be about either the aftermarket motors, or the PEC model of the drive (don't know if that's supposed to be the same rotation rate as the basic Celestar's drive).
Folks seem to be recommending about 10rpm on the knob. But is this supposed to be the slow/default rate, or the fast rate? The fast rate seems to be at least 4x faster than the slow rate. I guess in practice I feel like 10 rpm slow and 40 rpm fast would be OK, given how I use the hand knob, if one used pretty short button pushes: but I have a fantasy that maybe one day I'll try manually guided astrophotography, and so I don't want to end up with settings that are way too fast.
Don't want to make it be 10rpm and 40rpm if it's supposed to be 2.5rpm and 10rpm. Anyone with real practical experience know what the two speeds are supposed to be?
