Looks very nice. I am looking at one for my SCT. How fast can it go? I have read a few posts where the fastest speed is somewhat slow and that can be agonizing on a SCT when switching from an eyepiece to camera.
What would be a useful metric? It has two speed ranges, "accurate" and "fast" but I don't know how to translate steps per and what looks like a good linear in or out rate on a directly coupled rack and pinion setup to the belt an pulley used with the SCT screw and lever focuser. But thinking about it when I crank the SCT knob for a long move, it is a sort of partial turn, release and repeat motion. A continuously turning motor drive could have a slower rotational speed and still be as fast or faster and certainly a lot smoother.
My suggestion would be to send Pegasus the question. If they don't have a number I bet they will test a unit and give you the time to go lock to lock. They are a couple of responsive guys.
The preceding post suggests that all focuses in this price range are slow in comparison to high priced units. I simply don't know, But I have owned an SCT with a high price after market focuser and its virtue was that it had a slower fine focus.
I am very familiar with the endless cranking particularly when I started by moving the mirror the wrong way, But my primary reason for going with the motor drive now is to avoid having to go outside to adjust focus as the temperature goes down. If i put one on the SCT the dual advantage is the the reduction in shaking when focusing.
When i used to sit at the scope I used a foam ring on the SCT's focus knob to change the ratio and I felt better fine focusing. But I see a motor focus in the near future.
