The AT8IN is a great choice. Since you have plenty of mount and it's permanent it will work as well or better than the SCT option. You might also consider the AT10IN for only $100 more.
With either of these options you will need a different focal reducer setup (there is less need for any focal reducer with an f4 scope ... this is just an option if you want to go really fast).

There have been lots of discussions about remote control from the comfort of your house (or hot tub). Here's a link to the most recent - http://www.cloudynig...m-in-the-house/
Normally it is a good idea to have a solid remote control setup working before going on to something else but the video setup is integral to the remote control idea working. So it doesn't really matter - video first or remote control first ... you'll need to have both working together to do what you ultimately want to do.
Some of the things to think about ...
Do you want or need to do the initial alignment while at the scope or in the house?
With a good initial alignment is your mount accurate enough goto wise to put objects consistently in the fov? (if it's like my CGE the answer will be a strong yes ... even with a 10-11" scope working at f3.5-f4).
A small secondary scope (finder) is also a good option (even with an accurate CGE). Here a really inexpensive 2nd video camera and a small refractor will work well together. One nice benefit of video or other EAA hardware is that it makes the initial alignment routine even more accurate (the camera has the fov of an 8mm Plossl eyepiece, and it has cross hair capabilities).
The two "architectural" options for the remote configuration are: 1) extending all the connections between the scope and the house - this means the serial mount control, serial camera control, primary video, and finder video OR 2) placing a remote PC/laptop at the scope (with all it's direct connections for the previously mentioned connections) and then running a remote control/VNC server/client setup over a single Ethernet link to the a PC in the house. With this second option you also have to think about the primary video - whether or not to extend the primary video or to run a big monitor off of the PC in the house and view the whole PC desktop vs. just the video image.
#1 requires some different extension hardware and multiple line connections between the scope and the house but the PC in the house controlling everything operates just like it was sitting next to the scope.
#2 requires a second remote PC but less or no extension hardware. The PC in the house displays a window which is the remote screen of the PC sitting out at the scope. If you already have the laptop/remote PC this option is usually the less expensive of the two.
Yeah I know ... too much to think about.
I like the Rebel Yell idea.
