I have a refractor that has a 4 inch dia. objective lens cap. but that lens cap has a second lens cap in the center of it the second lens cap is only about an inch and a half across. when would a body have use for one and not the other? why are there two options? https://www.cloudynights.com/a...ctor-telescope-r2219 Safety, Situational Awareness and proficiency.

For a minute I owned a NVG monocular, it had a cap with it with a tiny hole in it, so they could be used in daylight, or lighted conditions, I imagine for testing and the like. Maybe this is something similar? For use in the day, or something, without burning out your eyeballs? Of course I would think one would use a tinted lens.

At the risk of sounding like a dunce -and not wanting to treat you like one bendable - do they separate? Maybe it's for the eyepiece? | |||

the eye piece is 1 1/4 , the small one in the center would be much too large. Safety, Situational Awareness and proficiency. Neck Ties, Hats and ammo brass, Never ,ever touch'em w/o asking first | |||

The small aperture is for looking at the moon, when you don't need the full objectives light gathering. Had one on my Vixen, but kind of miss it since I moved to a Stellarvue | |||
