I'm going to pick up a used William Optics BV from a local seller. Do you folks know what I should look out for?
Also, it comes with a 1.6x nosepiece but the seller is additionally selling a Siebert Optics 1.6x OCA. Will I need the additional component for my 14" f/4.7 Dob?
Thanks for the advice!

I have this BV and so far I can't get it to focus in my new 10" Dob. I have tried the 1.6x barlow that comes with it, but still no good. Perhaps the Siebert is needed to get it to focus? Ask the seller what he does?
