"Hi Jim,
Just wanted to send you a (very) belated thanks for rounding out your
collimation tool line with the 2-inch autocollimator and the sight tube
(Teletube). I now have a complete set of tools that enables my scopes
to perform better than ever.
Two features that I especially appreciate...
No slop! The tolerances are snug, but not over-tight. My old set of
tools always had some slop in them, so I could never be sure of the
collimation. Your tools eliminate the doubt. And your making the site
tube adjustable for focal ratio makes the tool fine for all my scopes.
Secondly, I appreciate the brightness of the images in the
autocollimator and Cat's Eye. No more straining to see the images. It's
now a piece of cake to see those stacking triangles!
The night after improving my secondary collimation with your Teletube,
my scope went deeper than ever before, bagging a mag. 17.8 quasar with
the 24. I'm currently enjoying wonderfully-detailed views of Mars.
When seeing permits, I get the full 50x per inch in the 24, even more
in the 8-inch. And besides improving my own scope, I've used your
tools to help others with theirs. I politely decline when they offer
their tools, and use the Cat's Eye tools instead.
So, thanks again for making these tools available. When I think of the
investment I have in telescopes and eyepieces, your collimation tools
are a bargain considering how much they improve telescope performance.
Clear skies,
Alex"
