How Long Before the S&P 500 Comes Back?

Posted By William Green

I'm soliciting (educated) guesses regarding when the S&P 500 will get back to where it was last October, i.e., about 1550. Any takers??? I'm feeling very bearish, so I'll say five years.

What does "well corrected" mean exactly?

Posted By William Green

The phrase "well corrected" is used a lot among amateur astronomers, but I have yet to see anyone explain exactly what the term means in the optics field. The phrase certainly has no intrinsic meaning, so to speak. I gather that it means "true to life" or "brings all colors to same focus" or some such.

Can anyone here (Mr. Christen, perhaps?) explain what this phrase means exactly in the optics business?

Oh, and another thing, what does the term "saturated" mean in the context of the color of an object when viewed through a scope? I gather that it means "intense" or "vivid," but, again, I've never seen anyone define the term.

In my field, law, words are our only tools, and I find that precise definitions are desirable, even necessary. I also find that not everyone has the same understanding of what words mean.

Thank you.

TOA-150 on a Losmandy G-11?

Posted By William Green

Has anyone observed (or even imaged) with this combination? I'm wondering whether I might risk putting a TOA-150 on a G-11 for visual. Other mounts in this weight class tend to be outside my price range.

Ed Ting, on his website, has a pic of such a set-up, but he expresses no opinion of its stability:

Thank you.

Takahashi Fine Focuser

Posted By William Green

The New FSQ scopes have built-in fine focusers, right? Why don't the TOA scopes have built-in fine focusers?

Starlight Focusers

Posted By William Green

Starlight focusers are greaseless, right? They never require re-lubing?

Thank you.

D & G Optical Achromats

I am considering purchase of a D&G 6" f/12, and I would appreciate receiving comments from those who own or have owned that telescope. If you prefer, you can send me a private message.

Thank you.

"Knowing" is a dud!

Posted By William Green

I give it a B- for plot, A+ for special effects (but every sci-fi movie has good special effects these days).

Say, what'd you think about BSG's finale? I thought it was somewhat satisfying, but I was hoping for more.... Kinda sad finale, really.

Land, Sea & Sky (a/k/a Texas Nautical Repair)

Posted By William Green

I was in Houston today and, as I usually do, I dropped by Land, Sea & Sky (a/k/a Texas Nautical Repair), the Takahashi distributor in the U.S.A. LSS is a *very* nice shop, with hundreds of items of interest. Among the items on display were a TOA-130, an FSQ-106, and an FSQ-85. Sakes alive, they are beautiful telescopes! Images of them do not do them justice.

Takahashi Schmidt-Cassegrain?

Posted By William Green

Art (or anyone),

Has Takahashi ever considered making another SCT? Was the original one discontinued due to lack of sales? It would make an exciting addition to their product line.

PV What?

Posted By William Green

With respect to the optical quality of a triplet-lens refractor, what does the phrase "certified as minimum 0.25PV" mean? Would "0.25PV" be good, bad, or mediocre? I think I know, but I'd rather have someone more knowledgeable explain this to me. smile

Thank you.
