Eudiascopic eyepiece - general lens layout
Lens Layout

This 5-lens eyepiece design combines the viewing comfort and large corrected field of Erfle-design eyepieces with the advantages of the popular Plossl design.

The fifth lens element offers a better sharpness and colour correction throughout the visible field and also results in a flatter focal plane.

Probably the most important feature is the optimized eye relief both in long and short focal length eyepieces of this type. The eyepieces have a scratch-resistant broadband multicoating. The robust coating meets US Military standards.

The 5 lens Eudiascopic eyepieces form a new eyepiece design in its own right - more than just a slightly modified Plossl design!

winged rubber eyeguard

TS Touch:
We sell each Baader Orthoscopic eyepiece with a comfortable winged rubber eyeguard - without extra charge! The eyeguard keeps stray light out of your eyes and improves viewing comfort.

The Genuine Orthos offer an excellent multi-coating. Other, similar looking eyepieces often have a more simple coating.

Orthoscopic eyepieces: general lens layout
Lens layout of the Baader Genuine Ortho eyepieces.

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-axis sharpness is required
- Finding out the limiting magnitude of a telescope - due to the eyepiece's enormous transmission
- double star observations
- eyepiece projection photography (Webcams, CCD cameras or SLR cameras)

"Phantom" Multi-Coating:
Baader GENUINE 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.

HYPERION Wide Angle Zoom Eyepiece 8-24mm - 1.25"

Baader Hyperion 8-24mm Click-Stop Zoom eyepiece - full view

Here you can well see the adjustable rubber eyeguard on the top of the eyepiece.

A high quality zoom eyepiece for demanding users who prefer to own one zoom eyepiece instead of a large selection of separate fixed focal length eyepieces. At 8mm focal length the Hyperion zoom has the same large field of view as the regular Hyperions. It narrows down to about the field of view of a Super Plossl at 24mm. This is still a lot more than many simpler zoom eyepieces!

Specifications and Features:

- Field of View 50 - 68 degrees
- (with click-stop for the focal lengths 8 / 12 / 16 / 20 / 24mm)
- incl. thread for adaptation to (nearly) all Celestron Ultima spotting scopes
- incl. thread for adaptation to all Carl Zeiss Diascope spotting scopes
- incl. extandable Helicoil rubber eyeguard
- incl. SP54 Hyperion thread for projection photography with compact digital cameras

The Hyperion Zoom comes with both a 1.25" and 2" barrel. When removed the Hyperion Zoom has a thread that connects to many spotting scopes. (See below)

Spotting Scope Use:

The Hyperion Zoom can also be used on many spotting scopes. It is compatible with the following spotting scopes:

- TS standard spotting scopes (55mm, 80mm and 100mm)
- Celestron spotting scopes (65mm, 80mm and 100mm)
- Skywatcher / Acuter spotting scopes
- Zeiss spotting scopes

In many cases the originally supplied zoom eyepiece limits the performance of a spotting scope. The Hyperion Zoom will improve image sharpness in most cases.
