The new focusser, continued...
Out with old, in with the new...
There was no baffle within the new, shorter draw-tube, either...
...as there was within the original, longer one.
The visual-back accommodates my diagonals easily, but most importantly, my fattest eyepiece...
Not that I'm going to be able to observe straight-through with this achromat, à la Japanese, although I might be able with those of shorter focal-lengths. I've already tested a 32mm Plossl straight-through, and I had to hold the eyepiece about an inch out and away from the visual-back in order to come to focus. Hmm, I could attach a short extension.
