I've been interested in Astronomy and science since as long as I can remember. A year ago I purchased my first 'real' telescope, a 10" Orion Intelliscope. I've also been a computer programmer for 20 years and as a true computer geek, I had to have a computer hooked up to my telecope.
The Intelliscope controller is terrific, but I really wanted to have something that would allow me to quickly look around an area of the sky for interesting objects to view. My initial experiments with hooking up my laptop to the telescope using Cartes du Ciel worked, but I found it to be too much hassle to bring out the laptop and table and I constantly had to watch out for the wire hanging between the laptop and telescope so I wouldn't trip on it and destroy some of my equipment.
My solution arrived when Software Bisque added support for the Intelliscope to TheSky Pocket Edition.
It's necessary to purchase a couple of cables to allow a Pocket PC to communicate with the Intelliscope conroller. See the Parts List section below for the parts, prices and links. You must connect the Orion RS232 cable to the controller, then connect that cable to the Pocket PC Serial Interface cable, then connect that cable to the Pocket PC itself. This setup is much simpler than using various null-modem cables and gender changers that are listed on Software Bisque's website.
Once I had both of the wires connected, I needed a way to mount the Pocket PC on the scope. I ended up putting a large piece of velcro on the telescope and adding a small section of velcro to the back of my Pocket PC. This allows me to quickly attach/detach the pocket pc and attach it at any angle, including upside down for tracking faint stars as displayed in the eyepiece.
I found the Pocket PC's screen to be far too bright in the dark, even at the dimmest setting. I resolved this problem by purchasing Rubylith from Scopestuff.com. By cutting a section to fit the screen, then breathing on the screen, I found it perfectly attached to the display for a very clear, dark red display which would not blow off even in a moderate wind.
After installing TheSky on the Pocket PC, it's necessary to download the latest patch from Software Bisque's website in order to have Intelliscope support. The demo version of TheSky doesn't include Intelliscope as an option in the list of supported scopes.
Turn on the Intelliscope controller and do the alignment for the controller (note: you can skip this step by just starting the controller in test mode by holding down the enter key when you power on the controller). With the Pocket PC connected to the Telescope and TheSky Pocket edition running, tap Telescope, Establish Link... 
You will be asked to point the scope vertically, then choose 2 alignment stars- the same procedure as the controller uses. One really nice feature of TheSky is that it remembers the 2 stars you used for alignment. If the controller powers off, this makes it very fast to re-align TheSky.
Once you are aligned, it will display how far off you are on the aligment. If you are within 1/2 a degree or so, I found the accuracy to be quite good. At this point I used the View, Night Vision Mode function to turn on the all-red display. With Rubylith, any green or blue colors tend to get washed out. When I turned on Night Vision, everything was very readable through the red film
You will now see a cross-hair indicator in the display. As you move the scope, the cross hair will follow your telescope's movements. If you move the telescope so the cross hair moves off the display, you must tap the Telescope, Center Cross Hair function in order to display the scope's current position. It would be very nice if there were a way for the display to just stay with the scope, but that doesn't seem to be an available feature. 
TheSky also has what would be a great feature called Slew. You can tap or search for a particular object and display the details about that object. You can then tap 'Slew' to bring up a screen that has a graphcial bar showing how far you have to go in Ra/Dec to reach the object. There is also an audible indicator so you can move it and hear different beeps indicating when you are getting close to the object. Unfortunately, it doesn't appear to work with the Intelliscope controller right now. I reported the problem to Software Bisque technical support and they emailed saying they would try to reproduce the problem. 
One limitation with the software is that you can't download object updates to TheSky without having the desktop version of the software. However, I found a nice utility written by Mark Crossley's at his website here:

This utility allows you to download comet information directly into TheSky Pocket Edition without having the desktop software.
Note: Links and prices were accurate 7/2005. Prices do not include shipping.
For Intelliscope owners who already have a Pocket PC device, this low-cost solution makes for very pleasant observing sessions. I think I've found my final computer-scope interface. At least until I build that permanent observatory...
