Explore Scientific Es 52° Eyepiece 3.0mm Astronomical Telescope Ultra Wide Angle Professional Argon Waterproof Eyepiec

 

Brand new & high quality

The new focal length and the 3mm 52° series of eyepieces have joined the Explore Scientific series of inert gas purifying and waterproof eyepieces. This eyepiece can be used in conjunction with the ED80mm f/6 interval triple lens "snatch away", which can produce a 160x eyepiece, which performs very well under good sight conditions. On the ED152 of f/8, for those nights with almost perfect eyesight, the 405X shooting effect can be achieved without the use of Focal Extender or Barlow, and it has a very comfortable 15mm eyeball release.

 

Explore Scientific 3mm 52° series waterproof eyepieces are specially designed for high-power coaxial observation. They are completely coated with EMD (enhanced multi-layer deposition) and coated with black-edged lenses, which can provide high-power planets at close distances. Contrast binary stars required for power observation, as well as bright and compact deep sky objects. These eyepieces have a 52-degree field of view and provide incredible value.
