Focusing on the GG

[ardea]

Back sometime I posted a question regarding a jewlers loupe for

focusing and was asked to share my findings. I'm 65 years young and

have 20/20 distant vision but do need reading glasses (2.5 diopter)

for the up close stuff. I purchased a clip on loupe from Donegon

Optical Co. It is a Behr loupe, model 55, 2" single. It has a spring

loaded clip that allows it to be attatched to the earpiece portion of

the eyeglass frame. You can rotate the optical portion of the loupe

into your field of view for critical focusing. With just the reading

glasses I can back away, about 12", from the GG while under the cloth

compose and rough focus then flip the loupe down for the fine

control. It is equivalent to my hand held 6x Scheider and it leaves

my hands free. I like it...your milage may vary....Regards,

Richard

Thanks for the tip. I also wear +2.5 glasses when under the hood, and I find it annoying to reach for the loupe, etc.

<p>The Behr clip-on loupes you mention are described <a href="http://www.doneganoptical.com/catalog/behr/" target="_blank">here</a> on the Donegon site.

Richard: I see no price list or anything on that website. What did your loupe cost? Where do you get them? Thanks. -jeff buckels

Jeff...I recall the price was around twenty dollars and I bought it from Donegon. Ken was kind enough to list the site link. Looking at the Behr catalog on that site, the item is listed as 55S-2. You will have to call Donegon for prices...good luck. Richard

I have a similar loupe which I used exclusively for quite a while. I do find, however, that a handheld loupe with opaque barrel allows me to focus without a darkcloth in surprisingly bright light, which the eyeglass loupe does not. I do still keep it in the bag, though.
