LOL I explained it in a pm. My personal scope was a Celestron NexStar 8GPS for the last three years which was amazingly accurate, but for various reasons I needed to have the newest model and the new SkyAlign. SSP has a 9.5" GPS that he's pretty pleased with. <A HREF="http://www.celestron.com/prod_pgs/tel/cpc_index.php" target="_blank">http://www.celestron.com/prod_pgs/tel/cpc_index.php</A>
