Jean-Charles in France has dissected his Skylux finder and reports thus...
"I've taken this finder apart, because I'm very curious about optics. To my great surprise, there is a small Schmidt-Pechan prism inside, like in expensive roof-prism binoculars !
It is always stated that good roof prisms are expensive because they are very difficult to manufacture, the required tolerances for the "roof" face are indeed very small. I'm amazed to find such a prism here !
This is my first refractor, I have no idea if this is a common feature.

This finder is in fact a 6x24. The field of view is 7.3°, and the apparent field of view is 44°. I've compared it in daylight with a small Zeiss monocular : the image is equally sharp in both devices, the monocular has only slightly more contrast. This finder is very good !
