I've decided to stick with the simple 5: ratio for now,as slightly smaller rollers will give me a step size of about 0.016m and I suspect that for a simple platform rather than a precision engineered mount a resolution smaller than this is pointless. I don't see why a friction drive is in any way inaccurate. Tried it out last night... this is my report copied across from an astro forum: I managed a test last night, this is an edit of my post in the 'what are you doing tonight' thread after sleeping on it. I then increased the delay, and eventually settled on about 64 milliseconds delay by the time clouds came in, which isn't bad given the estimate was ~68 and expected to need to speed up to allow for compression of the roller. These combine with the projects themselves to make Practical Arduino: Cool Projects for Open Source Hardware an invaluable reference for Arduino users of all levels. It is a Meade LX600 12" reflector with Starlock. We feel that spending hundreds of pounds on a commercial telescope mount suitable for decent astrophotography is a dull and uninteresting route to take. A nice combination of 3D printing and turning: Very chuffed with the fit - pushes in without shake. The wear resistant design keeps its performance over time. Not really an issue with the platform, I think I need to dose it with silicon polish at the very least. Why no encoders?

You can see they are a much simpler shape and how the 'new' sectors allow them to be horizontal. Although up to speed up tracking and down to slow it seemed logical, as up increases the delay and vice versa. A remote handset might be a useful addition, perhaps with a reduced set of controls. By the way Niel I spoke to the friend with the Telescope today. Final mode is the clever bit, you can save the current rate into eeprom as a new default, or you can restore the default for the current rate from eeprom. Its bearing surface is close to horizontal (horizontal at lowest point, a few degrees for practical sector designs) (convenient). The CGX-L German Equatorial Mount and Tripod was designed to support your telescope for both visual observation and astrophotography. I chose to add 10 cm to either side.
