Oh, OK. I thought that I recalled Bill writing this three years to announce that the 1278s and 1026s had started on their way from there to here. As to your...

Shneor; The Paragon series, so far as I know, will NOT have coma correction. This would I believe mess up their use with refractors and longer F ratio...
... I think University Optics introduced the Pretoria design (Klee and McDowell) in a couple of focal lengths in the 1980s, probably not in large scale...
Mike; Thanks for the correction/update. Sounds like the Pretoria design had other issues beyond the coma correction designed in. As I see it the problem with...
... Hi Thomas, Looking at the market for a 30mm ultrawidefield eyepiece, I would say that a large part of that market is for large dobs with fast f/ratios -...
Hi Rich, What you say is true, of course - but if you picked f/4.2 or thereabouts, you would be in the ballpark for most faster mirrors. Burgess is exactly the...
I also have a Paragon, and it is a superior eyepiece. If there was enough demand, I imagine TMB might design a better alternative to the Paracor. That seems...
I would also add that seeing as how with fast scopes, including Newtonians, so much of the visible error at the edge of the field is eyepiece related rather...
High Point Scientific is currently offering three BO/TMB Planetary eyepieces for the price of two. Sounds like quite a deal. I am not sure how long this...

Just a quick observing report from last night in Southern NJ... With my 8" dob. I tried to see Red Spot Jr on Jupiter as it transited at 9PM. Didn't see it -...
Hi Paul, I have a question for you and anyone else who's spent a lot of time on Epsilon Lyrae. Has anyone noticed a star almost between the two pairs? I was...
Mark, There are actually two stars between them as seen in most scopes. As hazy as it has been lately, one of the two must have dimmed out. Thanks, Tom Davis ...
Thanks, Tom. Just to let you know, I posted this question on Cloudy Nights and a gentleman responded to say that there are actually five stars close to the...
I do remember at least one star like you say between them, but was focused on the double-double so I do not recall specifics. Something to look for next time. ...
Mark, I did print a chart with Guide software for the area around the double-double and did just take my scope out a few minutes... Still pretty warm here too...
... Hi Paul, sorry I'm late writing a response and telling you thanks for the note here describing the stars close to Epsilon Lyrae. My telescope is a 4" achro...
One problem into which I occasionally run over the summer is condensation forming on the lens of my refractor if I set it up while the night is still warm. Is...
Mark; Normally condensation is caused by the scope being cooler than the outside environment. If you do not store the scope in an air conditioned environment...
Mark; Of course the rest of the year you can look forward to the opposite problem, the tube dewing up when you take it inside from the cooler outdoors at the...
