Super Wide Angle Focusable 70 ° Eyepieces in 50.8 mm (2 ") and 31.75 mm (1.25") NEW!

Make your telescope a powerful guiding scope!

These super wide-angle eyepieces are characterized by their large field of vision and their first-class workmanship.
Broadband multi-quality wide-angle eyepieces with 70 ° field of view and blackened lens edges, to reduce light scattering. All eyepieces are parafocal, 70 ° field of view ensures that no detail is lost. A high contrast and high transmission characterize this eyepiece series. In the eyepiece a laser-etched reticle is integrated, which, however, only about 60% of the field of view is large. With optional lighting, the crosshairs do not interfere. The crosshair can be focused and thus optimally adapted to the eyes of the beholder. Without illumination, the crosshair lifts slightly from the sky background. The optional lighting unit causes the crosshairs to light up red. The light intensity can be adjusted individually on the lighting unit.

INFO:

For observation with a telescope different eyepieces are required. For lunar, deep sky / galaxy observations a rather small magnification is needed. For planetary observations, however, a very high magnification is required:

30-50x magnification as an overview eyepiece and for lunar observations,
70-100 times for lunar, galaxy and fog observations,
140-200 times for planetary observations.

Our recommendation: Never exceed the telescope magnification by more than 2 times the lens diameter.

An example: If a telescope has a 90 mm lens, you should not exceed a 180x magnification.

The magnification is calculated as follows: Telescope focal length in mm / eyepiece in mm
An example: Telescope with 1000 mm focal length / eyepiece with 10 mm = 100x magnification in the telescope
