Baader Planetarium 1.25" 12.5mm Genuine Orthoscopic Eyepiece

R1,325.00

Baarder Planetarium 1.25" 12.5mm Orthoscopic eyepiece 

Orthoscopic eyepieces offer an excellent on-axis image sharpness.  Warmly recommended for viewing the planets.

The classical orthoscopic eyepiece design has several advantages compared with Plossl eyepieces or wide angle eyepieces. With its small number of lenses and only four glass-to-air surfaces (less than that is not considered useful) an excellent light throughput and contrast is the result. You get a clear, undistorted image.

Baader Genuine Orthos are particularly well suited for viewing the moon and the planets. On-axis sharpness is better than in conventional Plossls.

Applications:

  • Lunar and planetary observing - best possible on-axiz sharpness is required.
  • Finding out the limiting magnitude of a telescope - due to the eyepiece's enormous transmission.
  • Double star observations.
  • Eyepiecce projection photography (Webcams, CCD cameras or SLR cameras).

"Phantom" Multi-Coating:

Baader Geniune Orthos have a particularly good multi-coating which sets them apart from other, simpler Orthos and many other eyepiece lines.  They have an excellent full multi-coating, i.e. a very effective anti-reflective multi-layer coating on each glass-to-air surface.  This brings a better contrast and image brightness than a simpler coating.

Features:

  • Threaded for filters
  • Blackened edges
  • Phantom coated for excellent contrast
