My laptop doesn't have an RS-232 port (as usual) so I had buy a USB to RS232 converter (on ebay). After installing the proper ASCOM driver, my Celestron NexStar 114 can nicely be controlled from SkyMap. Just click on a star on the chart and the telescope slews there. Position/time synchronization is also really easy.
NOTE: Before you buy this item, do find out what an RS-232 port is, and if your computer doesn't have one, buy an adapter first.
