I have a William Optics binoviewer and I tried to use it for the first time with my new (for me) 16" Meade Lightbridge, but I could not reach focus. I am missing 1/16 of an inch inner focus, or maybe less.
I ran a test by removing the 2" to 1.25" adapter, and held the binoviewer by hand in the center of the focuser and I was able to reach and pass focus point by a very small fraction, just enough to see that the image starts to loose clarity.
After seeing that all I need is a very small extra inner focus, I tried to play around with the WO stock 1.6x barlow nosepiece and to my suprise, I can reach focus with the 2" to 1.25" adapter if I turn loose the barlow 3 complete turns. This moves the barlow slighly forward and away from the binoviewer. Does this barlow movement forward affect anything else, like image quality, or cropping the light cone? Is it OK to use it like this, or should i look for a better option?
