Here are some very nice comments made about Burbank Optical Company "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 refra ctor 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 ref ractor 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. R. Alvarez, 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. A. Crain, WI.
