Tak Vari-extender.  IIRC it is 1.5X and you add .5X for each
extension tube (it comes with 3 or 4).  Front side is Tak
visual thread, so you'll need a visual thread -> 2" adapter.
Rear is t-thread.  As with almost all Tak items it isn't 
cheap, but it does work quite well.  Quality is comparable
with Televue.

All barlows are zoom <g>.  The magnification is dependent upon
film frame -> barlow lens distance.
