Hi Allan,

That's a real nice feature having a clutch The temperature compensation shouldn't be hard to set up. One obvious thing to point out and it can cause a bit of head scratching is to make sure the compensation is running in the correct direction.

So as the scope cools it contracts so the focuser should wind out to compensate and keep you in focus. If you think it's running in reverse there is a switch on the SharpSky driver window under 'Temperature compensation' called 'Direction reverse'. Once checked this reverses the direction of only the temperature compensation.

Easiest way to check is set a really big 'steps/degree' value say 100 and then cool the sensor with something .... a bag of frozen peas and check the focuser moves in the correct direction.

Cheers & clear skies,

Dave
