with 2 inch barrel

The Sky-Watcher 2" Apex eyepiece series provide affordable and good quality eyepieces. Contains 3 lenses and are advanced models of the Barium series. Recommended for short focal length fast (F/5-8) telescopes for low power. Provides contrasty and sharap image even at the edges. Fully multi coated with an eye rubber and 2" standard filter thread. The 35mm Apex eyepiece is ideal for point and shoot digital cameras because of the long eye relief. The 2" eyepiece adaptor is designed especially for these eyepieces.

 Ideal for low magnification observations or afocal photography. These 2" eyepieces from GSO provide wide field of view despide the long focal length. The 5 elements privde well corrected field of view. All air-glass surfaces are fully multi coated. The longest focal length model with 50mm can be used in F/8 or slower telescopes.

These eyepieces are slightly modified symmetrical Plossls where both the distance between the pairs and the thickness of one lens had been increased. The model is similar to Brandons but the curvatures and materials make it different. Provides excellent image that can be achieved with a 4-lens design.

The Lacerta (modified symmetrical) Plossl eyepieces have 58 degrees field of view and above average correction at the edges, even in f/4.8 scopes. Some distortion can be noticed but it is much less significant that many 5-6 or 7 lens models. Eye relief is 17mm and 25mm. All lenses fully multi coated, edges of the lens and the eyepiece is internally painted black. Provides bright and contrasy image.

The Sky-Watcher 2" eyepiece provide 70 degrees field of view and are very easy to use. The eyepieces contain 5 lenses with all surfaces fully multi coated to achieve excellent light transmission and contrast. According to our tests objects even half a magnitude dimmer can be seen with these eyepieces than with some other models. Compatible with all 2" filters, making it possible to observe faint nebulae with UHC or OIII filters.

The 6 or 7 element eyepiece provides sharp images even at the edges. We've tested with a 300/1200 Newtonian telescope and the results were amazing. All surfaces fully multi coated resulting in excellent light transmission and high contrast. Easy to use thanks to the long eye relief and are nitrogen filled.
