ATM Refractors and projection TV's
Hello all...
I have a question or two, and hope you can be of help...
I was given a set of lenses from a projection TV, which are housed
in plastic tubes. There are two lenses in each tube: one is convex (appx
5.5" dia), the other (appx 5" dia) is flat (referring to the exposed
surfaces), and there are a few inches between the lenses. My questions
are: 1) Can these be used to make a refractor? 2) Or, since I have 6
of these, can they be re-worked to make binoculars?
The only other info I have regarding these lenses, are that they
are made by US Precision Lens, in Ohio, and the particular style/type
are Delta II. I know that the info i've supplied is rather vague, but
that is all i've got to go on. I'm hoping one of you Quincy/Columbo
types know something about this, or can point me in the right direction.
Thanks in advance...
BTW: i've been peering from the cyber-shadows for awhile now, and the
info here is very helpful. Last week, I saw first-light on my
16.5", f6.5 Newt/Dob. Saw M13 through a "sucker-hole" in
the clouds, here in light-polluted L.A.... WOW!! Can't wait
to drag this monster to dark skies!
