This is a neat little home built job, but works really well. Can I help it if I am a Telrad kind of guy? The base is machined to fit an 8-inch SCT but could be easily adapted to other scopes. It uses a two point spring tensioned adjustment for easy alignment. Includes a 90* prism diagonal and a focusing EP. THe focal length appears to be ~200mm and the EP gives identical views to my 25mm MA. So I would guess the power is 8X, but it will accept any 1-1/4" EP so you can up it if you want.
$60 including shipping in the US. I prefer paypal, but can work with a money order as well.
Thanks for looking,
P.S. I am raising cash for the LX-200 sale, so check out all my other stuff, too!
