Also, on a recent thread, someone had bought a Baader Clicklock and was impressed with it, but several of us mentioned that when using binoviewers with heavy eyepieces, we did not get great results.
This looks like a great way to improve on both attributes (the Baader SCT Clicklock adatper actually has about 40mm of light path length).
In an SCT, 38mm of back focus reduction will reduce the focal lenght by 100mm or so, and if the system was working at a reduced aperture, will restores about .2" to the system.
For a given pair of eyepieces, you get a bigger field and a brigter view, and less apeture reduction in most SCTs if the back focus was more than about 200mm
I am very pleased the Denkmeier is offering this option. I am hoping that they will soon start offering a Baader Quicklock compatible dovetail for people that want to do 1.25 diagonals.
There are a lot of compromiss when using Binoviewers, and many of them are direct consequences of light path length.
Looking forward to first reports.

I got one at NEAF ,make shure it threads on all the way I had to have my machinist friend rethread mine as the thread pitch was wrong.
Yeah, I just noticed mine does not thread on all the way either. I was an early adopter too. Will talk to Russ about it.
But I love the rest of the system and that light path reduction is most appreciated along with the considerably lighter weight of the system.
