Using an OCS (usually 1.6X - 2X ) you should be able to reach focus
If you prefer not to use an OCS than you can test the back focus by focusing a piece of paper on the moon (move the paper until the Moon is in focus on it).
You'll need 5"+ to be able to reach focus without using an OCS and will need a short optical path Diagonal (I use a Baader Prism) and a threaded attachment to the BV (to keep things short as possible)
In general using an OCS is a far easier option.

Thanks! I was read somewhere that said that a barlow lens would work. I don't have a barlow, so I tried my 2.5 powermate. It works, but the magnification is higher than I would like. Is there an ocs that is less than 200 dollars? Thanks again.
There might be but we need to know what BV you have.
