Baader Hyperion 8-24mm Mark IV Zoom 2.25x Barlow
Even Bestsellers can be improved: This most highly rated Hyperion zoom-eyepiece is available now in its fourth generation and has become a lot more versatile. The 290 gram housing is lighter by 80 grams and now features a slim 55 mm diameter.
MK IV Hyperion 8-24 mm Universal Zoom eyepiece & the 2.25x Hyperion Zoom Barlow & , does cover a magnification range from 3.6 to 24 mm .
The adjustable eyecup can be removed to expose a video/photo thread and create the maximum in "nose space". The click-stop action has been smoothed out to more easily access the magnification stops at 8/12/16/20 and 24mm. Click-stops are mandatory to easily and precisely set both eyepieces to the same focal length for effortless binocular observation without eye-strain. The zooming-mechanism as well as the inner zooming rails for all lens groups have been modified to improve cold temperature operation and the parfocality for each focal length has been fine tuned.
Most important however – the Mark IV offers almost 4 mm more back-focus. This is most beneficial for application with a multitude of spotting scopes. Many spotting scopes nowadays do allow the mechanical insertion of astronomical 1¼" eyepieces – but in many cases this combo cannot focus to infinity. By utilizing the supplied spotting-scope adapter ring "A", the Hyperion Universal Zoom almost reaches almost four mm deeper into the eyepiece clamp of all those spotters, to safely reach infinity focus. When removing the 1¼" nosepiece, a 1 3/8" thread inside the "A"-ring will make the Mark IV firmly thread onto all Celestron-Ultima spotters and it´s namesakes. Threaded adapters for many other famous spotting scope brands (that still don´t allow 1¼" eyepiece adaptation) will become available in the future – now that it makes sense to produce them.
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 it´s 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!
