Baader 36mm Hyperion Aspheric Telescope Eyepiece

Baader has evolved the wide field astronomical eyepiece to a new level with the introduction of the Hyperion Aspherics. The 31mm Baader Hyperion Aspheric 72º Modular Eyepiece is one of the world's first to incorporate aspheric surfaces! This new technology has allowed Baader to eliminate eyepiece aberrations without the usual penalty of extra lens elements, excessive size and weight, or higher

The Baader Hyperion-Aspherics are great for projection imaging, and are threaded to accept the full line of Hyperion Digital T-Rings for a robust direct attachment of almost any camera. The clever use of 2"x24tpi SCT threads for attaching the 2" barrel permits the Hyperion-Aspherics to directly thread onto the rear cell of popular SCTs. This results in the highest rigidity possible for imaging. Two barrel sizes are provided with each Hyperion Aspheric. The standard 2” barrel provides the full 72º field of view, and a special wide field 1-1/4" barrel provides the maximum true field ever in this barrel size, with a field stop of 1.265”(32mm)! - perfect for extracting every bit of field possible in 1.25" focusers or binoviewers.

I love it
I'm rather new to astronomy,(2 years, I just upgraded my 6 Dobsonian to a 10 Dobsonian, so the view I was getting with just the eyepiece that came with the new scope was quite amazing. After some careful research I decided to go with the Baader Hyperion 36mm, 2-1.25, and I was blown away.The night it came, it was a warm,clear night for viewing, considering I live in a Chicago suburb, and it was January, and the moon was full. I kept changing eyepieces to compare all the other views with this eyepiece, and it wasn't even close. I just started aiming the scope at what looked like an empty black sky, only to be blown away with how many stars, galaxies, and many other objects that were actually there. With the wide field of view and it's clarity make it seem like your looking out a window. I meant to be outside for about 20 minutes, but I got so caught up with the amazing views, I ended up being out for over an hour. The quality, and price make this eyepiece a no brainer. If all Baader eyepieces are this good, I'm going to be switching over all my existing ones. I think I'm spoiled now. If your not familiar with OPT, I can also highly recommend them. They ship very fast, and answer all my questions promptly.

Hyperion aspheric 36 mm
I have owned other Hyperions, also own the Pentax Zoom 6.5-19.5 mm and Hyperion Zoom, but this Hyperion aspheric excels in low power views with sharp views in almost 75 % of the field, excellent contrast, world class multicoatings ( no internal or external reflections , space-walk experience, a lot of eye reflief and excellent color balance. I think the BEST BUY for for wide fields.

Questions & Answers

Product Questions

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