Yeah, that saddle on the Starfinder is quite odd. Given the size and weight of the 10" OTA I would rather it be as close to the mount as possible but this seems to work. I guess if the cold and clouds allow, it would be reasonable to try the thing out before I get to messing with it.

I'm a bit confused. The starfinder came with AC drive. Has yours been converted to DC? If the gear needs adjusting just loosen or tighten the adjusting screw inside the motor housing. Really no lube needs to be applied to the motor but use it sparingly if you do. You don't want to gum it up.




Early StarFinders had AC drives and metal focusers. Later models had DC drives (which could use the Magellan II) and platic focusers. Otherwise, the same.

Motor run, no trackie new [Re: cheapersleeper]

Cranked it up tonight and the motor turns. I let it sit with the motor on for a while after zeroing out the RA circle and with that super light load it was tracking. Outside with the big 10" OTA and the counterweights needed to balance it, it was not tracking. I would think this points to my needing to adjust the clutch since the guy I got it from was using much lighter OTAs on it.

What think you, smart people?

Regards,
Brad

Most likely just the clutch. Mine was a real slipper and the person who owned it before me tightened it so much the spur was clicking over the worm! I did not have good luck with the DC drive on my 1997 model. But the mount was very solid and the scope was excellent. GW
