Celestron ( Baader ) 60 degree Binoviewers - Barlow ??

[Telescope40]

Hello all.  Own a pair of these binoviewers.  Had a good shufty around the web, looking for a barlow that may possibly fit.

Drawn a blank.  Anyone assist.

Regards in advance as always     John

I've got one of these binoviewers, mine has a screw in adaptor that has a 1.25" nosepiece that fits into any 1.25" fit Barlow. On some Barlows you can unscrew the optical element which then screws into the binoviewer nosepiece to give an overall lower magnification.

This TS Barlow is one of those that Peter describes. Alternatively do a Google search for "nosepiece barlow".

Thanks for the replies.  Looks like my pair does not have the screw in adaptor that fits any 1.25 fit barlow, that Peter mentions. . 

I can see a thread on the "objective"  ?? end of the viewers and this seems to be slightly smaller than 2 in, as the nosepiece of a 2 in Barlow I own, is just too big for the thread to work.

Back to the drawing board I guess.

Maybe an e mail to Celestron and / or Baader  as to the adaptor piece I am missing.

regards   John

It's possible that the binoviewers were originally intended as a microscope attachment and that the adaptor is available to suit astro use.
