Re: Encoders, yes or no?

If you are using a Gemini controller, you have the motor encoders.

?

So the question is what’s the point of axis encoders – it buys you the ability to use the mount in “push to” mode while keeping the Gemini-1 informed of where the mount is pointing.

?

Also if there’s any slip in the system the axis encoders act to correct for that.

?

Sadly the Gemini-2 doesn’t have code to support axis encoders which is a real shame.

?

René – is that any reason the axis encoder support couldn’t be ported across to the Gemini-2 – my guess is it should be trivial to do this – possibly even with support for higher resolution eoncoders?

All,
Sorry for the barrage of newby questions, I am working my way through the manual to get to grips with all the features on the G11, my first motorised eq, tonight's topic of interest is Encoders.
If I understand there are 2 types of Encoders, the type that is incorporated into the motor, this type uses pins on the motor din plugs to connect, and the other type that fits to the RA and DEC shafts and connects to Gemini via the encoder RJ45 socket..Please correct my if I am wrong!

I understand what they do so my questions are:
Except for manual guiding when attached to a computer running Stellarium were the benefit is obvious,? are they useful for any other purpose and worth the money?

What is the best type, motor or shaft?

Thank you in advance..
