OK. Another round of testing. Don you might find this interesting.
I started by lowering my truss pole ~35 mm to make sure I have enough in focus. I had the tunable top at the lowest position to start at essentially 0mm. The 30mm ES came into focus at ~9mm-10mm from the lowest setting. The ES 14mm 100 came to best focus at about ~14mm. The 9mm came into best focus at about ~15mm-16mm. Still a bit disappointed with the 9mm if I'm honest. I was expecting a better field. Maybe its because I am comparing it to the 14mm. Which is sensibly a perfect 100 degree field of correction.
I put the 8mm Delos in for a test. That came into focus just at what I estimated to be 1mm. Completely flat a pinpoint as well. But it was a Delos at F/5. What does one expect?
I tried the Pentax 10XW. Couldn't get it to come to focus. It needs more in focus then 8mm Delos. Didn't even try the 14mm Delos as it needs even more in focus then the Pentax.
Don I'd be interested to see your results with the 8mm Ethos if you have one to test. Actually if you have a ES 9mm 120 I would be interested to see that performance as that would not have the same eyepiece design as the 9mm ES 100 right?
