DESCRIPTION

Baader 36mm Hyperion Aspheric Eyepiece - 1.25"/ 2"

Baader has taken wide field eyepieces to a new level with the Hyperion 36mm Aspheric Eyepiece, bending their considerable technical expertise towards the creation of a refined and effective wide field eyepiece. The aspheric surfaces used within these exemplary new eyepieces utterly eliminate eyepiece aberrations in a much cleaner and more efficient way than was previously possible, utterly bypassing such pitfalls as extra lens elements, excessive size and weight, or higher cost.

Baader's Hyperion Aspheric eyepieces have been designed with projection imaging optimization in mind, and where created to be compatible with all Hyperion Digital T-Rings. This means that the Hyperion Aspheric Eyepiece can be attached to an incredibly wide array of cameras as well as telescopes. The design makes very efficient use of 2"X24tpi SCT threads with the 2" barrel. This feature allows these splendid eyepieces to attach directly onto the rear cell of most SCT's for maximum imaging rigidity.

QUESTIONS & ANSWERS

Ask a Question
  • Which of the Baader T2 adaptor rings is needed to couple to a DSLR-T2 coupling? Secondly, will a coma corrector, such as the Baader RICC-I work effectively with this eyepiece, or will the eyepiece design conflict with what the RICC-I is doing to the coma

    You will need an BA-HTA43/T2 adapter for conversion to T2. The RICC is not the best coma corrector to use for this eyepiece - the MPCC would be a better option.

  • What is the Apparent Field of View using the 1.25" barrel? The information gives 72 deg. for the 2" barrel but nothing for the 1.25" barrel. Thank you.

    The apparent FOV is limited by the field stop diameter of the 1.25" barrel and will be approximately 48 degrees.

  • Is that TELE VUE DIOPTRX - 2.00 DIOPTER accessory advertised on the same page, easily attachable to your 36mm eyepiece?

    Yes, you just need to pull off the rubber eyecup and twist the DioptRx base onto the shoulder underneath the M43 threads on top of the eyepiece.

    Unfortunately, we do not have a shipping scale with enough resolution to get a precise answer, but the difference in weight is no more than an ounce or two, as most of the mass (and all of the lenses) are the same in either configuration.

  • The description states 1.25" / 2".  If I have only a 1.25" focuser, can I use this lens?  If so, how?  And, what is the focal length of the this lens using a 1.25" focuser?   Thank you!

    Hello Laura, Thank you for your question. You indeed can use this lens with a 1.25" focuser since it comes with both 2" & 1.25" barrels. The focal length does not change when doing so but you will make your field of view narrower in the 1.25" mode becaus

  • Can this and The 31 also be used with Newtonians..?.    I only asked because someone stated it could only be used with that type of Telescope (SCT's)

    The short answer is yes, as long as you have a 2" focuser. The long answer is yes, but due to exit pupil restrictions and coma with fast Newtonians they may not work especially well below f/5. A fully dark adapted pupil in an adult observer's eye wi
