Can be used at both light-polluted and dark sky sites; blocks the light from mercury and sodium-vapour lamps
Wider 58 Degree Field of View: Comfortable eye relief averaging 16 mm across the series and focal lengths is between 2.5 mm to 25 mm; giving maximum detail and definition across the entire 58 degree field of view
Multi-coated Lense Design: Each eyepiece has 5 lens elements in 3 groups; with retaining high transmittance and contrast ratio with least lateral cchromatic aberration and scattering phenomenon; having a wide view
