I'd use a little caution and compare it to the Celestron Neximager. The Celestron is available with some software for $99.00 from alot of sources. The Neximager is USB compatable as well. I don't know how the ccd compares but a little research and you may find that it is better one way or the other. I've seen used Celestron's sell for around $70.00. Steve

I just saw this on ThinkGeek.com:
http://www.thinkgeek.com/gadgets/electronic/e19b/
It's a USB eyepiece. Here are the stats:
* Attaches to any telescope * Adapter ring for 24.5mm and 31.7mm * Save 1280 x 1040 video or photos to your computer * Uses a 1/2 inch, 1.3 megapixel image sensor * Attaches via USB cable to your computer
No, it's not amazing specs. But for $99, I might be willing to give it a try.
Any thoughts, ideas, comments?
