Not much success getting an answer on this question so I bit the bullet, wired up a switch for the ST4 guide port, and confirmed that the angular speed increases 50% from 15arc minutes per minute to 22.5 arc minutes per minute. And of course drops 50% to 7.5 arc minutes per minute so the earths rotation can take over for the negative direction control. Not the three degrees per minute (x12 speed) I was hoping for.

That leaves the question what is the speed of the manual control on the Star Explorer Pro 2i when using a phone to control the local hour angle?

Hope some-one knows? Cheers, PeterO
