Eyepieces

We are sorry there is no other version available

Of course you can use the Hyperion eyepieces with the telescope, but will show the coma which is typical for such a fast telescope (just like a camera would di, too). To get rid of the coma, we recommend combining your eyepieces with the 2" MPCC V-1 Mark III Newton Coma Correktor - SET: Visual and Photographic Version # 2458403 which can easily be combined with many eyepieces. This coma corrector neither changes the focal length nor the field of view.

Please note that the 36mm eyepiece will result in an exit pupil of 8mm with your telescope, which is probably too much for your eyes (typically, the human pupil doesn't open much farther than 7mm even for young people and under darkest skies). The 31mm eyepiece should be more useful with an exit pupil of ca. 6.9mm.

The diameter of the white tube is 63,3mm the knurled ring ist at 70mm and the dew shield has 74mm.

This prism is made especially for the old Maxbright bino-viewer, it is meant to be attached directly to the T-thread of the bino-viewer, mainly for terrestrial observations.

If you do not use a binoviewer, we'd recommend either a mirror diagonal like
Baader 2" BBHS ® Mirror Diagonal with 2" ClickLock Clamp # 2456115
Baader 2" ClickLock Diagonal Mirror # 2956100
Baader Zenith Prism Diagonal T-2/90 ° with 32mm Prism (T-2 part #14) # 2456005K (for binoviewers or if you only use 1.25" eyepieces)
for astronomical observations or one of these amicis for terrestrial observations:
Baader 2" Amici-erecting-prism 90° with 2" holder and 2" sleeve # 2956152 (also for high magnifications)
Baader1¼" Amici-erecting-prism 45° with 24mm free aperture # 2956150 (only for terrestrial observations, only 1.25")

You may need a reducer from 2" to 1.25", as barlow-lenses are usually made for 1.25"-eyepieces, if you don't already have one:

The Hyperion Barlow is meant to work best together with the Hyperion Zoom, Q-Barlow and VIP-barlow are good regular barlows, and both FFC and Abbe barlow are high-end. They can be inserted into a 1.25" clamp; only the FFC is a little bit more complicated as it was made also for large-format cameras.

In its 2.25x-configuration, it works with all 1.25" eyepieces, including the Hyperion Zoom (when the 1.25" nosepiece is used).
For 1.3x, it can only be used with eyepieces where no optics are inside of the 1.25" nosepiece, as the lens body has to be inserter into the nosepiece. So it can't be used in 1.3x-configuration with the Hyperion Zoom.
