"Keith
it is completely free of defects," R. Brent said, "and is without question the finest objective
I've ever used for astronomy."
"I have observed through Ralph
Hunter's BOC 6" F/8 refractor at the moon and Jupiter and the performance was superb! Thank you for your
service and for producing such excellent optics!" D. Dean, VA.
As to the 6" F/15…The
optics are excellent and the telescope has performed beautifully….Again, thanks for building a very fine instrument!
Keith. B. Riely, CA.
Mr. Larkin your 6"F/8 refractor resolves right down to its theoretical
limit and then some. For example, the stars W Leonis and B Delphini, while not fully resolvable, are nevertheless clearly
elongated. None of my larger reflactors can matchy the lens' performance on these stars…..With deep sky objects the
star clusters are the real standouts. The individual star images are sharply defined points. Especially memorable are NGC
2266, NGC 6819, M92, and NGC 7789. …Thanks again for all the skill and craftsmanship that went into making it.”
F. Guerro, Peru
"Keith I had a chance to use your refractor (6" F/15) under better seeing conditions last night,
and it was fantastic! I'm now a believer! Because of full moon, we looked only at Jupiter, Saturn and the Moon, but all of
these offered excellent contrast and showed more detail than I've seen with much larger scopes. Atmospheric conditions, clearly
not the telescope, were likiting seeing at 360x, and I can't wait for a better night. The chromatic correction is excellent,
really not a problem even on bright objects….." C. Jeskie, FL.
"Burbank Optical
I wanted to thank you for doing such a good job refiguring my 6" F/12 objective. It received a high degree of scrutiny by
my friends and I was considered by all to have an excellent figure." E. Crain, TX.
Good work Keith, keep it up. J Pons, CA.
6" F/8 What
a fantastic scope…. Your optical quality in the star test is excellent….. God speed on continuing the fine workmanship
and business.”
D. Thayer, OR.
“The images in the 6” F/15 achro are very sharp. Probably the sharpest I've ever seen. My 7” apo
doesn't give that kind of performance. The images were so sharp I stayed up all Saturday night….The image of NGC 7006
was the best I recall ever seeing, even in a ____14” at a dark-sky location. And, of course, Swaturn was very impressive,
the best I recall ever seeing it…..I set up my 10”______Newtonian a few nights earlier, and there was no comparison
in performance. …your refractor has consistently given the best images of any telescope I have. Your 6" F/15 refractor
is just an excellent, beautiful, instrument. Thanks! T. Binghamton, UK.
"The 10" F/8
objective performs magnificently! Planetary and deep space viewing are superb. You've really outdone yourself with the
quality of the lens. Thanks so much for a job well done Keith & Debbie L. Dunn, AZ. (Hanson Road
Observatory)
Keith Larkin, You are a master at what
you do....I'm sure one day you folks will be on your way to a large telescope making firm. Love using my Brandon eyepieces
on my 6"F/15 for both lunar, planetary, and solar observing. P. Jewett, WI.
