Andreas, The 7.3-22mm Leica Vario Zooms showed up today from APM with the 1.25" adapters. I put them together and your were correct, I am able to merge the image even with my rather small IPD. It was forecast to be clear tonight but was raining an hour ago. Must be the new equipment curse.
I will let you and everyone know how they work when the skies clear.
Bob, you are scaring me! My IPD is also too narrow to binoview eyepieces like Pentax XW and I have been happily cruising along with my Pans and Brandons.
I'm not sure I really want to know what you think of the Leica Varios. It could be expensive.
Fellow Pin Heads: The results are in from this morning's viewing session and it is not favorable for us narrow-eyed folks. I too cannot use Pentax XW's due to a 56mm IPD. With the Leica Vario 20x-60x zooms this morning. I could merge the image at the lowest power settings but could not merge the image at the high power settings. I guesstimate that you probably need at least 60mm or better to be able to use the full range of these zooms. I also couldn't get the images to merge in my 2" Sieberts. The eyepieces were close enough together but the combination of my physiology with the zooms was not a good match.
I also attempted to use the ASPH's in the 2" Siebert and it too was a no go. It is a shame that God gave me such a pin head. My wife commented this morning that she is wall-eyed. Maybe I will use her as a surrogate observer for my BV/zoom sessions "Tell me what your seeing honey. How does the Great Red Spot look tonight?" Sheesh. Guess they will be up for sale shortly <sob>.

Bob, don't give up too soon!
First, you could try to generally use the 22-7.3mm zooms barlowed. This would enable using short focal lengths with their long focal lengths settings where you still can merge the images.
Second, you could mechanically modify the zoom's adapters to enable the zooms getting closer together.
Third, you could convert the eyecups into narrower ones as described here for the ASPHs.
Or a mixture of all three modifications. I'm still hopeful that you could find a satisfying solution.
Andreas, Too much added complexity for the experience. As they say here in Florida, "The juice isn't worth the squeeze". I like things fairly simple and to add more glass and more complexity seems to defeat the purpose of the zooms which is to have multiple focal lengths in one set of ep's. My darn IPD has been a stumbling block for binoviewing since day one. I have to carefully choose ep's that work with my narrow IPD. I had collected pairs of Pentax XW's only to find that my IPD would not allow the images to merge. It was a sad day because I really like those ep's. I am envious of others that do not have similar restrictions. At this point, I will remain satisfied with my 24mm Pans and 18mm BGAO's along with pairs of Brandon flat tops. It was a fun experiment. Not all experiments end in success but the attempts are always interesting. Bob
