The Tele Vue NP127is just got a make-over! Both the optical and mechanical designs have been revised to further reduce atmospheric defocusing ability. A new lens prescription delivers smaller spot sizes over a broader wavelength, a stainless steel lens cell provides better thermal stability, and advanced multi-coatings maximize contrast and transmission. The new Televue NP127is telescope has a new 10:1 focuser pinion assembly, and a longer captive dew shield and strikes quite a pose with gloss black anodized metal on the dew shield and rear cell. The new NP127is kept its predecessor's fast f/5.2, flat-field optics and the ability to image across a 52mm diagonal sensor. All Tele Vue imaging system accessories are compatible with the new NP127is.
