I got a BO cheapy about a year ago. It wouldn't work in my reflectors so I tried the 1.9X Barlow with an extension tube from Scope Stuff. Still wouldn't work. I recently got the 1.25X OCA form Siebert and now it works fine in the reflectors. In my 200K Klevzov f/10 scope it not only doesn't work no matter what, you cannot even see any starlight getting through the eyepieces! The scope's mirror looks interesting, but I really wanted to see some stars. Any suggestions.
