Telescope eyepieces as loupes

clw54

If you want a powerful loupe, just take a telescople eyepiece and look at your coin through it backwards. It works like a charm! You'll have to hold it very close and get the light on it from the side, but it's not too difficult.

I would think that there would be peripheral distortion, unless its a really low powered scope.

I forgot to mention that you have to take the eyepiece out of the scope.

No you don't! Just have a neighbor down the street hold your coin.



My gawd claw, you're a genius! Were you galileo in a past life? I tried it with a 32mm on pocket change and it reveals every nick, gouge and ding too well. I also found the foam in my carrying case has gone bad and has stuck to some of the eyepiece lenses. What a mess.

I tried that with a nagler and a radian the coins didnt look to "swell"

Empress Jayne still looks great.

Mac used to use part of a rifle scope if I remember correctly.

where the heck has he been!?

As much as I'd like to smile knowingly and take credit for discovering this, I have to give credit to somebody else. I read it somewhere, and don't recall where. It might have even been on these boards.

What size eyepiece? 20mm, 12.5mm, 9mm?

clw54

I've used 25mm and 9mm. The 25 is easy to use. The 9 is tricky, because you have to fold back the rubber part and get the light to the side just right. If you're looking at diagnostics the 9 might be necessary, but it will definitely do the job. I don't think anything smaller than the 9 would work very well.

Hey now your talking telescopes another very expensive hobby im into . As far as distortion on eye piecses. if your using a better eye piece they are corrected so there should be no distortion on the edges . hey i have a 2.5 mm try that one you can probally see right through the coin..

There will be distortion w/ even some of the more expensive eyepieces, IE Televue, Zeiss etc. The only eye piece i have used w/ some success is the ziess abbe orthos.

One of my favorite lenses is a 512X glass from a big refractor. On my desk I
use a 5" lens from an X-ray machine. Also use a 8X glass from an industrial
spectometer. Have about eight lenses I use extensively and a small microscope,
but still need a good microscope.

How big?

I might as well add my name to the astronomers on this list, it's my passion(coins are a close second) Big time deepsky observer(galaxies clusters nebulae etc.) My vanity plate is
M1-M110. Now can anyone figure that one out? I'm also halfway on the Herschel-400!

Okay, I can't stand it anymore, who is Empress Jane?

The refractor is only 4", but it's the biggest I have ready access to.

Messier list M1 being the crab nebula to M100 being the sattelite galaxy of Andromeda. My favorite? NGC7000.
Speaking of the Herschel 400. You ever hear of Jay Freeman? He just completed the list w/ the use of his lil 55mm Vixen fluorite.

Pretty sweet. Ive owned two 6" refractors, one a F/8 the other a F/12. At the obsevatory at school i have access to a 8" & 12" Clark refractors! Sweet scopes, both F/15

Hey, a 4" refractor is a great scope. On Monday night I saw the ring nebula(M57!) and the double cluster in Perseus(great shots both) through a friend's 4". Come visit our club's website CAS
