Achieving focus with binoviewers

[astro1965]

Hi all,I have recently purchased a Lunt 50THa solar scope and I am trying to achieve focus with a burgess binoviewer and have been having no luck.
I have been told(from cloudy nights) that I can achieve focus using a 2X and 1.5X barlow nosepieces.Has anybody tried this set up and achieved focus,using a Lunt50THa scope?I know siebert optics has adaptors,but thought I would try this method first.
Also any ideas where I can get a hold of a 2X and 1.5X barlow nosepieces?
Cheers,Nick.

Not sure if a normal barlow lens will work but I use a Glass Path Corrector which extends the focal point out further.

Something like this, depending on what binoviewer you have.
