The standard I think for driving a scope is a 4-wire bipolar stepper. Then for the driver need to think about step size - the motor have a certain number of steps per revolution, and this is increased by the mount gears, and then if the driver can do micro stepping.

Yes the above motor will do that, it can use both fields for high torque or it can use half the fields for micro stepping.
Initially I just want to do direct drive nothing fancy ,but getting these motor's from kick off means I won't need to upgrade later..
The mount side still giving me grief lol,, just don't know what to go with

This looks good. www.stellarjourney.com/index.php?r=site/equipment_onstepI might have a go at onstep at some stage. Get an old mount to try it out. He has some good info on choosing a stepper/driver. But first I might just try driving the mount with a nunchuk via arduino. Put a little zwo with a camera lens on it and view that on a phone ?

The more i look into the arduino projects the more I like the stuff I see. I think there is a market for the kit in astronomy and I'm going to add a section on the forum and try and draw in more folk who have done it or want to give it a go

Look at this on eBay www.ebay.co.uk/itm/252870211847Hi Chris, yes it's addictive by looks of it.. the above kit is what I'm going to buy next.. it's a pretty decent lot of kit in it to get started. Accelerometer, Bluetooth module ect Looking forward to pushing the arduino for Astronomy more on here.
