I have both SN6 Pro Plus and The Sky X.
TSX PRO with the camera add on like Marc says, is as close as your going to get for what you want.
The camera add on adds focusing, filter selection, as well as auto guiding and CCD/DSLR control. Add plate solving into the mix as well although I think you get that with out the camera add on. TSX offers a 90 day trial of the camera add on so you don't have to purchase everything at once.
Having said that I don't really like the planetarium on TSX, I much prefer SN6. To be honest though I rarely look at the planetarium. I generally know what I'm looking for before start it up anyway so I just type the object in click find, click slew, calibrate the guiding, take an image, plate solve, re Center object,
reengage guiding , press go on my image series. All done from my recliner in the living room via ipad and vnc whilst watching a movie
.
I think the camera addon still has a lot of maturing to do. It doesn't offer dithering ATM. And the "Take series" could be a bit more sophisticated by adding a bit more automation like filter selection and focus between a series. Presently you have to manually select a filter and manually auto focus But I'm sure these things will come in time.
Cheers
