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.
Another comment. Five feet is quite short for use in the field. Some USB adapters add length, but you may also want to budget for another extension cable.
Finally, I control my mount with a Linux powered netbook running Debian Linux, and the program Cartes du Ciel. In addition I installed the package Indi-bin. The USB device that pops up on the computer is usually /dev/ttyUSB0. You will need to ensure your user is in the "dialout" group. Even then you may run into trouble "writing" to the USB device. The simplest workaround is to make /dev/ttyUSB0 universally writable by issuing the following command as root, or by prefacing the following command with "sudo":
chmod 666 /dev/ttyUSB0
The problem is that this cable has a 4pin wide RJ11 male connector, also known as a 4p4c (4 pin 4 connector) end which does not seat correctly in the Aux ports on the Celestron. While I have not seen a 4p4c to 6p4c cable yet I did see adapters that could be re-crimped onto the end of this cable - http://www.amazon.com/Monoprice-Round-Solid-50-Piece-107269/dp/B005E2Y7EY/ref=sr_1_6?s=electronics&ie=UTF8&qid=1398675855&sr=1-6&keywords=rj11+4p4c+to+6p4c+adapter
Here is hoping Celestron will fix this oversight soon.
the controlling software from Celestron and upgrading the hand controller's firmware I am now able to use Celestron's NexRemote
software to direct the scope from my laptop ! And after downloading the ASCOM drivers and the star program Cartes du Ciel
I am now able to direct the scope to any object in the night sky from that star program. AWESOME !
