Hi Fernando,
I used a G11s for a couple of years before upgrading it to a Gemini 2.
Your Qs
1. No. It is not a goto system and has no way of knowing where it is pointed - (but q3 suggests you may be able to do something!)
2. The auto guiding is best done using a shoestring GPUSB connected to the hand controller port. This can be put through a splitter so you can have the hand controller connected as well. Any software like PHD will then be able to supply the auto guiding corrections to the mount.
3. Yes. These are digital setting circles and should let you drop any object on the chip. The analogue setting circles that come standard with the mount were usually good enough for me to get something on an Apsc chip at 1100mm focal length.
You may be able to take the output from the digital setting circles into your pc, which would let you use them with the sky x or any planetarium software. However, the fastest slew rate of a g11S is far too slow to be worth trying to slew the scope. So as long as you are not planning on unattended imaging with automated meridian flips and multiple target objects, this setup will be perfect for imaging at focal lengths below 2m.
Cheers,
Andrew.
