Ok, I admit I'm not too swift on the uptake, but what is the "high" "low" thing? Looks like two eye pieces for the same spy glass, only with closures like dampers on a bbq grill.

High and Low. My grandfather had an old telescope that had your 'damper's'. That is just to protect the lens. Lens glass is very soft and needs protecting against the elements (weather!!) I am sure you will find that each eyepiece gives you different magnification OR a different viewing field.

If they don't there may be a lens or two missing in the main body of the scope where the different elements are located. They are usually held in place with screw in rings.

Niner,

"...Ok, I admit I'm not too swift on the uptake, but what is the "high" "low" thing? Looks like two eye pieces for the same spy glass, only with closures like dampers on a bbq grill..."

Taken from an earlier thread:

"From: Training Manual - Signalling 1907

TELESCOPE SIGNALLING (MkII)

This telescope when closed is 11 1/2 inches long; it has three draws, the outside tube being covered with leather. The power of the eye-piece can be increased by substituting two additional lenses for those nearest the eye. These additional lenses are mounted in a seperate tube, and carried when not in use in a leather case. When the lower power eye-piece is used, the distant object appears to be magnified 15 times, with the higher power the magnification is increased to 30 times; the two sets of lenses are marked L ands H respectively.

As the telescope not only magifies the distant object but everything else within its field of view as well, it will be understood thatalthough the distant object may be highly magnified , it will probably be more difficult to discern owing to the corresponding high magnification of particles of dust, moisture, &c. in the air. The lowerpower eye-piece is therefore provided for general use and the higher is reserved for particularly favourable weather, or in countries where the atmosphere is abnormally clear.

The telescope when closed is protected by leather caps, and is provided with a shoulder strap which passes through fairways on the caps and the seperate case for the alternate lenses. "

Any help?

Tom

The lawn is nice isn't it.

Probably all the fertiliser from 3 dogs and a cat.

The shot through the 'scope is taken with the low power lense in place. High power was just a blur.

Can't wait to get it out to the range.

Got a question

MAGNIFICATION I THINK.......
