Meades new PWA (Premium Wide Angle) series is effectively a new version of their previous 82 UWA series, which is still available as of November 2020. Click here to simulate the field of viewhttps://astronomy.tools/. Edited by timmbottoni, 03 November 2014 - 08:49 PM. Its long 20mm of eye relief, screw-up eyecup and large eye lens makes Orions Lanthanum a pleasure to use. This eyepiece is ideal for higher power work on planets and double stars since it is very sharp, contrasty and has a generous 82 degree field of view. Observing while seated is a much better experience. A 100 degree field of view provides the user with almost 1.5 times the area of an 82 degree eyepiece. For me, anything 60 degrees or greater feels sufficiently wide. It sounds like at $65 a piece it would be hard to do any better. I see only two, a 9mm and a 6mm. All marketing. 15mm Stellarvue is identical to the 14mm ES 82, field curvature and all, as noted above. I had the pleasure of looking through all of the Optimus eyepieces with Vic at the DSSP. Going Wider: Five 100-Degree Eyepieces Compared, A Beginners Guide to Telescope Eyepieces, Price and Quality in a High-Power Zoom: SVBONY 3mm-8mm Zoom Review, Celestron Tabletop Tripod Review: Sometimes Smaller is Better. I tested this set on f/6 apo refractors and f/5 to f/6 Newtonian reflectors, concentrating on comparing on-axis and off-axis sharpness. Please note: Internationally, grading systems used at institutions of higher educations may differ substantially. At TUM, grades from 1 to 5 are assigned. Of the lower-cost 82 models, this was a good choice overall for both optics and mechanics. This is a superb eyepiece for the money, with the bonus of argon-filled waterproof construction to keep moisture from penetrating and fogging the eyepiece on humid nights. The value for current overall gradeis the numerical value corresponding to your current overall letter grade. If the grading system of your university uses letter grades, you can assign a number to each letter grade. : ), Call us at: 530 823 7796 Open Mon-Fri 9-5 Pacific Time, Read the review of the Stellarvue Optimus eyepieces by Tony Hallas in the May 2017 issue of Astronomy, Our EOP eyepieces are now loaded into AstronomyTools database and application. At least I think they are new because I can't find anything about these focal lengths, they currently have 4, 8, and 15mm available. They were identical to the UWANs (and 5 other brands of the same eyepieces). The 13mm Televue Ethos is $658, the Televue 13mm Nagler is $335. Program Fees: 0 - 10,000 (per semester) Academic Ranking of World Universities (ARWU) #48, QS World University . Don, I know the FS size controls the AFOV, but I thought the F/L was inherent to the optical design? Edit: For clarification, I am referring to the apparent field of view of eyepieces, not the true field of view. Eye relief is an excellent 17 mm, longer than in more premium models, and the eyecup is extendable. (Yeah, yeah, I know that's asking a lot.). Pros: Lightest 100 with good eye relief. Those look just like the WO UWANs, and they are in the exact same focal lengths. FWIW I looked at the Pleiades yesterday with a 32mm Plossl, a 24mm UFF (~65 AFOV) with my XT10 which has the same focal length as your telescope. Edited by jrbarnett, 08 October 2014 - 02:40 PM. I have a 4.5mm Morpheus and a 4.7mm Ethos SX. Stars are Nagler-class sharp to the edge even on the Newtonians. The only cons I've noticed is that they are big and heavy and change the balance point for my small scope+cheap mount and like any other optical system they have to cool down to ambient temp to get the best view (which takes a few minutes). But once i start using something around 1m+ in focal length, I find 70+ degrees is preferable, and if it matches nicely with the scope, the more apparent field the merrier. I was surprised! I've owned all the WO UWAN in the past but sold off all of them except the 4mm. My conclusion upon testing this 100 group was that performance was more or less commensurate with price. Pros: Good off-axis sharpness and eye relief, but . I test ZWOs new ASIAir Mini. However, stars began to bloat 60 percent out from the center and were quite distorted at the edge. Unfortunately EP focal lengths are rarely exactly accurate and in the case of the axioms they were obviously paying homage to the original 23mm axiom and 24mm was close enough to call a 23. Its smaller, lighter, and cheaper than the bigger ASIAir Plus astrophoto computer, but is it as good? The focal length choices seems a bit odd to me: 28mm, 16mm, 7mm and 4mm, but perhaps more focal lengths will fill in the gaps later. The specifications state an 86 apparent field but it appeared to be the same as the other 82 models. Make no mistake, these are large and heavy eyepieces, with some requiring 2-inch focusers. Note the Meades middle-weight 638 gram mass and that both the Meade and Omegon are just for 2-inch focusers, requiring more costly 2-inch filters. The jump from 50 to 70 provides a much larger leap than 70 to 100 to my eyes. There are more expensive products, but do they perform any better? Field Stop: 13.6 mm Number of Lens Elements & Groups: 7 elements Special Features: Tapered insert tube Comes with Dust Caps? And the included velvety storage bag is very nice. I bought this and the 4.7mm on a whim when picking up an SV60. So that this makes sense - take your 30mm SuperView, focus on a nice cluster of stars (M45 akaPleiades is a great one). Uhno. Once you look through eyepieces with 82 apparent fields, all lesser eyepieces give the impression of looking down a tunnel. Its barrel fits only 2-inch focusers and so requires more costly 2-inch filters. Despite its modest price and sharp optics, I cant recommend it. Do you search for top universities and information on admission requirements, language certificates (TOEFL/IELTS) and application deadlines? Either model represents an excellent value in a mega-wide eyepiece. You sometimes feel more like you are actually there, in the view. But I still prefer the Ethos SX on Uranus and Neptune because it gives me a much longer time between nudges and that allows me to relax more when looking. Personally, I find the 70-72 degree range perfect for my needs and taste; and there are plenty of offerings in that range with adequate effective eye relief for eyeglass wearers. But then again, thats more or less the point the eyepiece gets out of the way so you no longer have the sense you are looking through a round porthole or window. With the eyecup folded down it can be used with eyeglasses, but only just. 70 is fine at low power, 78-85 fine at medium power, but I prefer 110 at high power. The Meade and Omegon represent great values. In the refractor, though, the 4.5 Morpheus comes into its own, with plenty of drift time with a focal length over 1100mm shorter.

I just ordered two 1.25" 32 mm 52 degree GSO eyepieces from Agena Astro because I would like to have that wider TFOV. I can easily watch a close double drift past the field stop of a type 6 Nagler and often do. These are $65 or so.., Observing in Northern/Southern Michigan, USA, The NEAF Report from nPAE Precision Astro Engineering. I tested nine brands of 82 eyepieces, all in the 13 mm to 16 mm range, a focal length that provides moderate power on most telescopes and so is suitable for all types of viewing. Anything is possible. Field stops are different. Has anyone out there tried both or have any thoughts? Oh, barlowed the 15mm starts to show curvature around the 80-85% mark for my eye and the 4 and the 8mm the same since already barlowed. Looks like at this time they are all available. For planets 30-40 deg. Just teasing you, David. Bottom Line: A good, economical choice for Schmidt-Cassegrains. The latter had good optical performance, but with a twist-up eyecup mechanism that was stiff and greasy in the unit I tested. At 564 grams even with its 2-inch adapter tube, Stellarvues Optimus is the lightest of the 100 set, a consideration for balancing smaller telescopes. For 1.25" 82 eyepieces, I have a mixed set of Televue, ES, and UWA. But what matters is who you buy it from, the specifications, customer service, reliability, and price (of course), when making your actual purchasing decision. Our EUW eyepieces are now loaded into AstronomyTools database and application. Alan Dyer is an astrophotographer and astronomy author based in Alberta, Canada. 2023 Astromart.com. The contrast is good and the view is clear from edge to edge. No. Reducer Flatteners for other telescopes, Finderscope Eyepieces with Focusing Reticle, Barlows to double the power of your eyepieces, Stellarvue 15 mm Ultra Wide Angle 1.25" Eyepiece - EUW-15.0, Stellarvue 4 mm Ultra Wide Angle 1.25" Eyepiece - EUW-04.0, Stellarvue 8 mm Ultra Wide Angle 1.25" Eyepiece - EUW-08.0, Stellarvue Ultra Wide Angle Eyepiece Set - EUW-SET. Not saying that's a bad thing, just sort of distracting. I test ZWOs new ASIAir Mini. Very fast shipping and packaging. LMU - Ludwig-Maximilians-Universitt Mnchen. It comes with a pouch with a belt clip. For 1.25" 82 eyepieces, I have a mixed set of Televue, ES, and UWA. Each of the eight elements are fully multi-coated, edge blackened and the lens barrel and baffles are similarly dark black. For low power, large FOV, I recommend you limit the eyepiece focal length to ~35 mm (thus a 7 mm exit pupil.) any limitations are just limitations and can not be named "favorite", (2) acceptable (not a favorite) eyepiece AFOV depends from nature of observing object. The A-T 28UWA/StellarVue 82 and APM 30UFF has already been mentioned in this thread. They slap on the "15mm" on the side and everybody assumes it is actually 15mm, when it is really 14mm. I've been thinking about getting the 15mm as my first non-cheapo eyepiece so I'm looking forward to hearing what you think about it. These wider fields allow me to see things with my peripheral vision and make the whole experience that much more comfortable and enjoyable. Crappy skies so I havnt used them yet. (Cheaper products abound, but you never know what you'll get. They made their own products as well. I doubt this as JOC won't sell eyepieces to any US brand other than ES since 2012. The tool will then calculate your grade in the German grading system. It's nominally 1mm more of eye relief, but it seems like more because the edges of the field are just that bit more accessible. Pros: Best eye relief and off-axis star images. Night Sky Challenges and the Astronomical League. Or know anything about the design and/or origins? All of my scopes are on manual mounts, so I agree, the larger the AFOV the better. Teasing me? The eyepieces rival Televue but they were sold to fund an Ethos.I missed the 16mm and regretted it as it's a very useful focal length. I find the 82 degree fields of my Explore Scientific 9mm to be less accessible, though it is a nice sharp view. Maybe the following might help: This shows the FoV for a 28mm 82 deg, a 25mm plossl, and a 7mm Xcel EP on my Orion XT8 ( 203mm/1200mm = f5.9), Jon, I 'll be needing some guidance soon; the 28/82 is on the way: using that and my 7mm Xcel as a base, I'll be upgrading/replacing the others to flesh out a "good" set. Several functions may not work. All marketing. No question they set the standard. I figured out my preferred fov and eye relief by purchasing used eyepieces here on CN. The LHD series includes four other focal lengths, all with 20mm eye relief, and with the 4mm, 6mm and 9mm eyepieces having 1.25-inch barrels but very tall form factors. Why 5 stars? Stellarvue 4 mm Ultra Wide Angle 1.25" Eyepiece - EUW-04.. The 28mm has a 2" barrel, the rest are 1.25". Pros: Very comfortable eye relief; superb optics. On my f/5 to f/6 test scopes, stars started to distort 50 percent out from the center and were quite bloated at the edge, the poorest optical performance of the group, but one thats commensurate with price. Well to be honest, United Optics products tend to be quite good, whether branded as WO or SV, or something else. Tight eye relief, a lot of field curvature, and edge-of-field brightening at f/10. The attractive price makes it easier to collect the complete set of three, along with the 8mm and 4mm models. EPs: ES 2 . Are these made by United Optical? The eye relief is comfortable but a bit tight at around 12mm. Pros: Lightest 100 with good eye relief. You would recognize the names of the OEMs if I told you. An important factor is whether you have astigmatism in your observing eye and need to wear glasses when observing,. For a lighter, lower-cost alternative, and for 1.25-inch focusers, you might wish to consider an 82 eyepiece. Get a chair! You may see the shadow of the secondary mirror with this eyepiece and exit pupil. While stars do bloat a little at the very edge, the 83 SSW comes close to matching a Nagler for optical performance, with the benefit of slightly longer 14mm eye relief and a more comfortable twist-up eyecup. A frequent example on here is the 84 degrees of the Docter 12.5, which is a highly accessible but wide field. There are many really good ones available in this category, all across the price spectrum. Accessories, Astrophotography gear, Reviews. There's also a comfort factor. For Messier 24 ("Delle Caustiche") even in short focal scope 100 deg. This is the largest and heaviest of the 1.25-inch eyepieces, with a mass of 400 grams. Note: For definitions of basic eyepiece characteristics mentioned below, see Ed Tings A Beginners Guide to Telescope Eyepieces. I had the 15mm and it lasted 2 weeks in my case. Bottom Line: A well-made eyepiece but costly for the performance. The only cost I had to eat was shipping, but spending $20 to rent an eyepiece is worth it to me. Bottom Line: The standard of performance for 100 eyepieces. Edited by betacygni, 05 March 2023 - 10:45 AM. Thanks for any input if anyone is still watching here. However, with your eye positioned where it needs to be to see the whole field, the field partially blacks out with squirming kidney-bean shadows (technically called spherical aberration of the exit pupil). Bottom Line: Very good performance vs. price. Has similar build quality to TeleVue and has a better feel than its APM counterpart. Good correction comes with a price. Today, they report 4mm, 8mm, and 15mm and are $50 apiece less expensive, at $149 each. I do most of my observing with 82 degree eyepieces. Here is a good listing of who actually makes applianceshttp://www.appliancehase/make.shtml. Other than that, this eyepiece is excellent and certainly merits your consideration. They are obviously not a redesigned barrel on the old ones. Click here to create one. Pros: Very good optics and waterproof construction. To be totally fair, not all eyeglass wearers are the same or require the same amount of eye relief. Please note that this tool is only intended to provide a first orientation and the results are in no way binding. Introducing the new Stellarvue Ultra Wide Angle eyepiece series.
