TV Binovue and TEC-6...use without Barlow??

Hello all,

I have a TV Binovue but no ep pairs as of yet...
I have FS-102, TV-76 and TEC-6. As I contemplate which ep pairs to acquire, (mostly for use with the TEC) I wonder whether or not I can get away with using the BV sans Barlow. 8O
At 152mm aperture, 1800mm focal length (f/12) the mags would be extreme with anything shorter than 15mm focal length if I have to use Barlow to reach focus.
I understand most SCT's have enough mirror travel to reach focus w/o the use of the Barlow...could it be the same for the 6" MAK I wonder?
Any advice would be appreciated, thanks!
-Mike

I have a TEC6 and use it with Zeiss viewer (same as Baader from AP), I use it primarily with high power eyepieces on planets, when I ordered mine I specifically requested ample backfocus for binoviewing.
Perhaps you can contact Yuri with this question as he is most qualified to give you an answer.
