It's hard to predict how an antique telescope will perform.
The Manent is fantastic. Made in the 1920 - 1930 by the French telescope maker Mauric Manent. It's a pleasure to observe with. Even the lenses are uncoated it still gives a very good contrast and color. Sharp and beautifull color. Even at 250x the images were crisp and the color with no aberrations. The focuser is very nice.That's the kind of telescopes I like very much.
