If you are purchasing a $150 eyepiece for a telescope, you shouldn't just do your research here on Amazon. This is basically a big store filled with everything, kind of like cyber Walmart. Just because they carry something it doesn't mean that they have experts listing it. You should do your research on virtually ANY other website which all list EXACTLY how the modularity works on these eyepieces. This message also goes to Joe who gave this eyepiece a 1-star review because he was too lazy and too hasty to actually read how these eyepieces work. I am not trying to scold anyone here but please research technical things from appropriate sources. Last but not least this eyepiece is amazing and the modularity is something to behold. these is FOV los and some aberration when attaching different rings, but overall it is an incredibly effective way of increasing your eyepiece variety without spending money on extra eyepieces. **Q: How exactly does this connect to a dslr when using it with a dobsonian?** A: yes ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great images, outstanding value *by K***R on November 23, 2018* Update 1/15/19I recently spent an entire evening looking at the moon, M42, Betelgeuse, Rigel and Mars with a variety of eyepieces, my fantasy of looking elsewhere shattered by clouds. I compared the Baader Hyperion Aspheric with shorter focal length eyepieces with comparable fields of view, an unfair comparison, but so be it. The telescope was a well-calibrated f6 8" with a finely honed Pegasus primary (Strehl ~ 0.99) and a 1/30th wave secondary from Protostar. The scope and EPs cooled outside from late afternoon. Seeing was average from my relatively dark backyard site.On axis, the 31mm Hyperion was as good as the best of them. When a very bright object (mpon, Rigel) was placed just out of view, there was perhaps a bit more scatter than in much more expensive eyepieces. I noticed the slightest bit of coma for objects at the extreme edge of the field of view that was absent from the other shorter focal length EPs, but this is to be expected. If I focused on an object nearthe edge of the FOV, it appeared sharp and contrasty right across the field of view.Equal to a 31mm Nagler? No. A great value for a "finder" EP? Very definitely.Original post:I used to own Televue and Pentax eyepieces, but the case containing them mysteriously disappeared during a house move. Freed from all that pricey glass, I decided to explore less expensive options to rebuild my collection, hoping that the originals would eventually re-appear. The Baader Hyperion 31mm aspheric replaced a 35mm Panoptic, and honestly, I don't miss it. The Hyperion is lighter, requires no coma correction on scopes f/6 or greater, has a somewhat wider field of view, throws up very bright, very contrasty views even in my somewhat light-polluted back yard, has virtually no internal reflections,and has a very sharp fieldstop. The image quality is notably better than standard Baader Hyperions (which, it should be said, are still an excellent value), more like a Baader Morpheus, IMHO. I experienced a bit of kidney-beaning on first use, but never since, whereas this was a constant challenge with the Panoptic. And it is 1/2 the price! Highly, highly recommended. ### ⭐⭐⭐⭐⭐ Finally *by W***M on November 10, 2024* At last, I have a full set of these. Been using Hyperion eyepieces for well over a decade 5mm is heavy and tall and it's too much magnification for my small refractor unless conditions are really good, but it is excellent for my larger scope. Unlike my other eyepieces, the 5mm does not break down to be used in my 2inch focuser. Not a deal breaker as I rarely breakdown the others. ### ⭐⭐⭐⭐⭐ I LIKE IT! *by B***N on December 13, 2017* I wasn't expecting a tremendous lot from a $200 eyepiece, but this eyepiece is a very pleasant surprise. I got it on the recommendation of an acquaintance who raved about it. He mostly uses TeleVue Ethos eyepieces, and when he told me about this eyepiece, I had to check it out. Once I saw the price, I was ready to be let down, but I ordered it anyway. I have a 9.25" Celestron SCT with a 2" TeleVue diagonal. This eyepiece maintains clarity and chromatic consistency all the way to the edge of the field of view. This size eyepiece is excellent for looking at deep sky objects, and, with a light reduction filter, good for looking at the moon. I have also viewed the sun (through a white light filter) using this eyepiece, but there was very little surface activity, so it was kind of... meh. For me, this is a really good low power eyepiece, and I am very satisfied with it.If you usually go out and spend $$$$ on TeleVue and ExploreScientific super-wide AFOV eyepieces, and you need a good low power eyepiece, I think you might want to check this thing out. It is a lot smaller and lighter than 100- to 120-degree AFOV eyepieces, since there is a lot less glass, but it delivers clear and sharp views. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/12404340-baader-1-25-and-2-hyperion-eyepiece-5mm-hyp-5](https://www.desertcart.pl/products/12404340-baader-1-25-and-2-hyperion-eyepiece-5mm-hyp-5) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-08*
