Donald, That is one nice scope. I don't see it on the Burgess website. How much? And how long will it take to receive? Charlie ... Rosenfield, announces his...

Hi Donald Let us know how it works for you. I have been using my Siebert Optics OCA Corrector for low power (1.3x) but might pick up the Burgess one as well. I...
What exactly does "couldn't find any that would work" mean? There was not enought travel to focus? I'm just trying to understand what did not work, if anyone...
As I understood him, Jim, Bill couldn't properly focus with those correctors. The new one that Thomas designed will work just fine. Donald What exactly does...

Hi, Thomas Your BO/TMB Planetary eyepieces look like a very nice job, and especially at the price. Is there a lower limit of a refractor focal ratio below...
Work and weather have kept me from doing much observing, but last night I set up with about 100 other amateurs at a local dark sky site to try to glimpse Deep...
... Hi Mark, It will all depend on the quality of the optics. The BSD101 should have no problems with the 4mm BO/TMB Planetary eyepiece, that I have tested. It...
Finally got outside to test the 1278. The night was not the best. A haze developed and an occasional cloud, but the images were not satisfying in another...
These eyepieces sound fantastic in all regards! Truly, something to look forward to. One suggestion: from a marketing perspective, since they will be ...
Just my 27¢, Bill. Is the problem the same when you rotate the focuser? When you rotate the ocular? When you change oculars? When you look straight through,...
Donald. Thanks for the response. The problem remains with different oculars. Have not tried rotating the focuser. Have not tried on stars without the...
Do you have the Crayford focuser on your 127? I got one on my 127f8 and the focuser was not perfectly square. Star testing the scope showed a classical...
Wow Thomas, sounds great! When will they be available? Soon I hope! Allen -- No virus found in this outgoing message. Checked by AVG Anti-Virus. Version:...
Last I heard, Bill is out of the Crayfords. From the description of your symptoms, it sounds like the focuser is not aligned. The stock focuser by its design...
Burgess website said the new corrector required 1.1/4 inches of intravel when the new OCA is used with the Burgess Binoviewer. What scopes will have that much...
Both of my BO 102f6 and 127f8 have over 5 inches of focus tube travel. With the 1.9x corrector, my focusers still have in-travel available. If you are using a...
... Bill: My suggesion would be to just place an ep right into the focuser (without diagonal) and see if it improves the viewing. Maybe the focuser is off...

Tom: It's not cross threaded. The problem is mostly right and left horizontal to the ground. I think the Teflon would be spaced at 120 degree spacing and...
Thanks for your response, Thomas. Eventually, I may want to start a collection of "LE" type eyepieces. Earlier on when I invited Laura (my) wife to step up...
William; I would like to disagree with you regarding R&P focusers. There are good and poor examples as there are good and poor Crayfords. The large 3.5"...
All... I really think you need to take a little time and analyze why the Crayford is smoother. Hint: Round vs. triangle. There will always be vibration and...
Hi Rich : I guess that you are right about the R&P vs Crayford . I have never used a Feather Touch or Astro Physics before . My only experience is with the...
