<\/a><\/p>\nWhat’s new in the model “Universal Zoom Mark IV”?<\/h3>\n
Even Bestsellers can be improved: The fourth generation of this eyepiece weighs 290 gram and is lighter by 80 grams than its predecessor – it now has 55 mm diameter to become useful in dual mode from 55 mm interpupillary distance, both features make it especially desirable for use with bino-viewers. The adjustable eyecup can be removed to expose the M43 video\/photo thread and create the maximum “nose space” for using it on binocular viewers with the supplied winged rubber eyecups – for maximum concentration on the target. 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 parfocalty for each focal length has been finetuned.<\/p>\n
Most important however\u00a0\u2013 the Mark IV offers almost 4 mm more backfocus. This is most beneficial for application with a multitude of spotting scopes. Two different Adapters for telescope and spotting scope adaptation are included with the eyepiece (Spotting-Scope Adapter \u201eA\u201c and Telescope-Adapter \u201eB\u201c). Read more at “Telescope-sided Connections”).<\/p>\n
The Mark IV comes with both the 2″ and 1\u00bc” nosepieces mounted, each nosepiece having it\u00b4s own dust cap and both nosepieces are threaded to accept either 1\u00bc” 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 \u2013 which fastens onto many tripod legs just as well, to serve as a bin for all dustcaps that may go astray otherwise.<\/p>\n
As usual with Baader eyepieces, the Mark IV offers an M43 photo\/video thread on top of the eyepiece, to allow attachment of\u00a0any desired DSLR or T-2 accessory for mounting\u00a0a video-camera by means of the optional M43\/T-2 adapter ring\u00a0 #2958080<\/a>. Unchanged is the optical quality, 68\u00b0 field of view at highest magnification, Phantom Group multicoatings, a large adjustable eyecup or alternatively two M43 rubber eyecups for bino viewing. An optional spacer ring M43\/M43 (#2954250<\/a>) with\u00a07,5 mm extension enables the user to increase\u00a0the height of these eyecups in case of need.<\/p>\n The Mark IV likewise accepts adaptation of the 2.25x Hyperion-Barlow onto the 1\u00bc” 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\u00a0set together with the 2.25x Hyperion Barlow (#2454827)<\/a><\/p>\n Please also note our detailed\u00a0Hyperion Universal Zoom Mark IV Instruction manual<\/a>\u00a0(also under the tab “Downloads”) for further information.<\/strong><\/p>\n The Hyperion zoom Mark III comes with two removable barrels (1\u00bc “and 2″), as well as an 2″ SC-thread for direct connection on telescopes or mirrors\/prisms with the optional 2″\/2″ changer ring (#1508080).<\/p>\n Furthermore included in the scope of supply are two adapters of different height – both with 1 3\/8” inner threads – for following uses:<\/p>\n Please see the\u00a0instruction manual<\/a>\u00a0for more information on changing both Adapters.<\/p>\n As usual with Baader eyepieces, the Mark IV offers an M43 photo\/video thread on top of the eyepiece to directly attach most video cameras. It also allows attachment of\u00a0any desired DSLR or T-2 accessory by means of the optional M43\/T-2 adapter ring\u00a0 #2958080<\/a>.\u00a0An optional spacer ring M43\/M43 (#2954250<\/a>) with\u00a07,5 mm extension enables the user to increase\u00a0the height of the included eyecups in case of need or to attach M43 cameras without touching the lenses.<\/p>\n A further connection capability offers the SP54-system thread-in the form of the Hyperion DT ring system. For this system, the transition ring M43\/SP54 #2958086 is suitable for the Mark IV zoom eyepiece. This adapter enables the connection of all common camera lenses on the Hyperion zoom to use it for Eyepiece Projection. Those connection rings are called “Hyperion DT rings”, see our section “Eyepiece accessories” .<\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\n<\/a><\/p>\nConnection Options and Included Items<\/h3>\n

\nMany spotting scopes nowadays do allow\u00a0the mechanical insertion of astronomical 1\u00bc”\u00a0eyepieces\u00a0\u2013 but in many cases this combo cannot focus to infinity. By utilizing the supplied spotting-scope adapter ring “A”, the Hyperion Universal Zoom reaches almost\u00a0four mm deeper into the eyepiece clamp of all those spotters, to safely\u00a0reach infinity focus. When removing the 1\u00bc”\u00a0nosepiece, a 1 3\/8″ thread inside the “A”-ring will make the Mark IV firmly thread\u00a0onto all Celestron-Ultima spotters and it\u00b4s namesakes. Optional available is a bayonet-adapter for Zeiss Diascope-spotters (#2454500<\/a>). Threaded adapters\u00a0for many other famous spotting scope brands (that still don\u00b4t allow\u00a01\u00bc”\u00a0eyepiece adaptation) will become available in the future\u00a0\u2013 now that it makes sense to produce them<\/li>\n
\nWhen 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<\/a>).<\/li>\n<\/ul>\n<\/a>
