I have bought a funny little scope on a flea market, that seems to be very rare here in Germany. Its a Bausch & Lomb Criterion 4000 (4" SCT) including a rifle-type finder scope and a 24mm kellner(?) eyepiece. I even did not star-test ist. So, can anybody tell me anything about this instrument, e.g. f-ratio, expectable quality, approx. manufacturing time etc. Thank in advance Chris just got this stuff from auction its comes two lance 18mm and 30mm but when i look at sky at night i don't see anythings can some one help me ?
