Used – Baader Hyperion 8-24mm Zoom + 2.25x Barlow Mark IV

MK IV Hyperion 8-24 mm Universal Zoom eyepiece & the 2.25x Hyperion Zoom Barlow covering a magnification range from 3.6 to 24 mm

When using the Mark IV on a telescope though, the “B”-ring (supplied) should be chosen instead, to keep the bottom of the eyepiece flush with the upper end of most star diagonals. Otherwise the bottom 2″ SC-threaded holding ring that holds the “A” or “B” ring in place may directly rest on the clamping screws of the star diagonal. The supplied 2″ SC-ring also allows the Mark IV to firmly mount the eyepiece onto any SC-thread, especially onto our 2″ clicklock star diagonal, with the help of the 2″/2″ adapter (#1508020)

The Mark IV comes with both the 2″ and 1¼” nosepieces mounted, each nosepiece having its own dust cap and both nose pieces being threaded to accept either 1¼” or 2″ eyepiece filters. Both nosepieces are free of the hated undercuts. Instead our proprietary Zero-Tilt Safety-Kerfs provide an added measure of security by reducing the tendency of an eyepiece to slip from an unlocked eyepiece clamp. An additional little feature is the Baader-yellow soft pouch with integrated belt strap – which fastens onto many tripod legs just as well, to serve as a bin for all dust caps that may go astray otherwise.

As usual with Baader eyepieces, the Mark IV offers an M43 photo/video thread on top of the eyepiece, to allow attachment of any desired DSLR or T-2 accessory for mounting a video-camera by means of the optional M43/T-2 adapter ring #2958080. Unchanged is the optical quality, 68° field of view at highest magnification, Phantom Group multi-coatings, a large adjustable eyecup or alternatively two M43 rubber eyecups for bino’ viewing. An optional spacer ring M43/M43 (#2954250) with 7,5 mm extension enables the user to increase the height of these eyecups in case of need.

The Mark IV likewise accepts adaptation of the 2.25x Hyperion-Barlow onto the 1¼” nosepiece, to transform into a high power zoom, featuring the magnification range of 3.6 to 10.7 mm. The Hyperion Universal Zoom Mark IV is available individually  (#2454826) or as set together with the 2.25x Hyperion Barlow (#2454827)

Whilst this superior zoom eyepiece is a suitable for many spotting scopes, the Barlow is not designed to be used on a spotting scope!
