Autoguiding on a NexStar Evolution SCT

[nddeyne]

Has anyone been successful at autoguiding a Celestron NexStar Evolution SCT? It doesn't seem to have an autoguiding connection on the mount. Some articles mention a way to do this through a PC, but fail to go into further detail.

I'm aware that a wedge is needed for this, I just can't seem to find anyone that actually did autoguiding on this type of scope...

Anyone? There are plenty of these wedges for sale, has anyone used one?

Found this on cloudy nights ...

Seems doable

'have an Evolution and you can autoguide them via ascom with the normal computer connection - and it should even work wirelessly.

But almost all autoguide software would need to use PulseGuide commands - and those are only enabled by ascom when the mount is on a wedge and in equatorial tracking mode - rather than alt-azimuth.

So yes - effectively you do need a wedge to autoguide, but you don't need a special guiding port. You just need computer control of the mount via ascom.'
