... Lots of experience with soda-lime glass but not with Pyrex. I do know that the main differences are in the coefficients of thermal expansion, and those...
... WG: Apparently, the situation with "Pyrex" is rather complex, and not all "Pyrex" is what we normally think of it as. Pyrex kitchen glassware manufactured...
... Unfortunately, Corning has stopped manufacturing Pyrex, even in Ireland, and the Schott equivalent is extremely expensive. Professional mirror makers are...
... My first mirror was a 6" f/8 at age 16. Mirror turned out pretty good. The biggest problem was a rough surface because I was in a hurry during figuring. I...
I just uploaded 3 shots of my 130mm f/5 with a replacement 2" focuser to my album David B's stuff. The focuser was taken off my 10" f/5 Antares Dob. I...
... WG: I meant to say, "no refund nature." Meaning, PayPal aside (and they just got me out of a bad deal as well, even where the seller OFFERED a refund),...
... WG: That's a good word for it, Geoff, tolerable. I had a 6" f/15 Jaegers and it was very lovely so long as you weren't focused on a bright object. Color...
... WG: 1/4 wave doesn't say much to me, look at the other supplied specs and decide their veracity. If 1/4 wave was truly "diffraction limited" then what...
... Not experience, but repeating the word on the street: "If you are happy with the results of the 6", tackle an intermediate size (8 or 10) before jumping to...
I think I should try this, starting with the traditional 6" f/8, all I have read says that this is as good a first experience as any, plus I have a GSO of that...
Thanks for the input, Wayne, more comments and questions follow... ... Since when is that a reason not to buy/build another scope? ... Now some meat. Isn't 1/4...
... WG: That's the problem with eyepiece reviews, most people don't stop to think that the eyepiece is an optical element in a unique chain--- here is the...
Just a little confirmation of what Wayne says here but primarily concerned with bino-viewing. The 24mm gives you the most you can get out of a bino-viewer...
... Interesting...in this post you touch on the imponderables of eyepieces...why some people like some and despise others. This is something I've become aware...
... WG: A "review" of sorts really, done impromptu off the top of my head as I rushed to head out the door. So forgive the few typos that were in there. ... ...
... WG: Yes. If I had to pick only one Panoptic, it would be the 27. Overall, I feel it is the best balance between size and weight, cost, FOV and comfort of...
Wow Wayne! What a history lesson on the TV Panoptic's along with their application... BTW, I ordered the book yesterday I was talking about the other day. It ...
... WG: I thought I would pass on this thread but I see that while there are opinions out there, there aren't many /informed/ opinions. I have actually used...
It worked OK for me. Interesting pic! Wayne Lord/Star_Geezer Citrus Heights, CA ________________________________ From: Joseph <josephrome77@...> To:...
NO, there is a reason they stoped the 15mm. It did not do well. I only seen one and would not buy one. I think there is a 40mm also, but I have not seen...
Another question about the Panoptics, I have on one or 2 occasions seen on Astromart a 15mm / 1.25" TV Panoptic listed for sale. I don't see the 15mm 1.25"...
... Although I've never used either of them, I've heard extremely positive reports about both...they are among the best eyepieces on the market, bar none. ...
Went to the Mansfield dam last night (11-10-09) and set up early. Of course Jupiter had shown itself before dark, its equatorial bans shown clearly with some...
... WG: I would think it much more important right now to keep focused on finding a new place to move the hell out of where you are. ... WG: Yeah. How many...
