Very worth it for me, as I like to use bino-viewers. But the longer FL units are certainly useful. Comparing Orion Telescope & Binoculars options, it appears that a Kellner can be found for almost half the price of a Plossl of the same focal length, although there are also equally cheap Plossls available from various sellers on Amazon that are highly comparable. I started with the Celestron zoom. Plossl eyepieces are very good and fairly inexpensive, typically between $25 and $50 each. They are also good for those who have astigmatism because they are designed to be more forgiving with eye placement. Note to spectacle wearers: Plssl eyepieces with 15mm and longer focal lengths are good choices for spectacle wearers. Most of Celestrons entry-level telescopes are sold with Kellners (and other cheap but reasonable-quality designs like RKEs or Konigs), whereas their more expensive SCTs tend to come with a single 25mm Plossl. Every review suggests replacing the 10mm Kellner eyepiece (and possibly 25mm Kellner) that comes with it. Other eyepieces of more advanced design can have better eye relief and field of view. For your application and the eyepieces you have or are going to get, you really dont need anything else. I loved my Baader Mark-IV 8mm-24mm Zoom+Barlow combo in my 8" EdgeHD. I think I will go for the BHZ because, as you say, I will be able to use it now and into the future. The telescope comes with a 2x Barlow so I was thinking of getting one of the zooms you recommended. But your point is well taken. They are not that expensive I would pay about $100 for both eye pieces. I want to help you select the best eyepieces for your budget and your telescope. If you do upgrade, youll probably want to go for a different eyepiece design than a Plosslsomething with a sharper image or a wider field of view or a longer eye relief (or all three.). In the 1990s Meade instruments came up with a new design for the Meade 4000 line similar to Plossl that added a fifth glass element on top of the two pairs (4 total). For that purpose it is probably easier to find one to borrow. Lets take a look. How does that field of view impact the viewing experience? Plossls tend to come with large, ground-standing Dobsonians, whereas youre more likely to find a Kellner sold with a tabletop Dobsonian. So its best for use during duller times when there isnt much brightness visible. NEW. Omni 56mm Eyepiece - 2" Learn More. I wants to install one in house(fixed place) another I need movable. Centuries of improvements led to achromatic refractors, where the primary lens is made up of two lenses of different types of glass, which reduces false color fringing and allows the telescope to be made considerably more compact. You can email me also. The only reason it's in this list because of its price and a long focal point. As new anti-reflection coatings were developed, it became possible to actually make use of complex lens arrangements (not just in relatively simple 4-element systems but also in convoluted, extreme wide-field eyepieces such as the TeleVue Nagler). Even though there are more sophisticated types of EPs, Plossls hit the right spot between high-quality optics and price. i dont have 1 of everything, and i bought the best i could afford on a low budget; meade and orion. These are highly sought after ep's, and hold their value well. It also produces an erect image, meaning you see what youre viewing rather than seeing everything upside down or sideways as some types do. It doesnt matter what type of telescope you have, as long as your scope takes these standard sizes. https://www.amazon.com/Orion-8829-Wide-Field-Telescope-Eyepiece/dp/B000M89H7C/ref=sr_1_2?dchild=1&keywords=Orion+Q70&qid=1606584502&sr=8-2, The Explore Scientific 68 degree series would be better but at a much higher price. There is no shortage of accessories for the Nexstar series. I had a newer - purchased in 2016 Meade 32mm (white lettering) that was no better than the older 32mm 4000. This type of design also helps provide for eye relief; its a better experience if your eyes. The result in magnification is the same and the eye relief associated with the eyepiece is retained or, in some cases, actually lengthened a bit. The 66-degree AFOV of the Gold Line series provides a 32% wider field than Plossl eyepieces. Best suited for telescopes with f-ratios f6 or slower. Some of these series also offer 2 eyepieces for telescopes that can accept 2 eyepieces. Those that still come with Huygens and Ramsdens are generally cheap and low quality, since practically the only reason to use those designs in modern times is that they are extremely cheap to manufacture. Eye relief is the distance from the eye lens to your eyeball, and the higher the better (within reason). These are exceptional eyepieces, and only available on the used market nowadays. Save my name, email, and website in this browser for the next time I comment. The zoom can be used with any 1.25 focuser too. You can add the specialty single FL eyepieces later if you wish. Pentax K-70 Astrophotography: The Ultimate Camera on a Budget! If well made, Plossls are bright, with good contrast, and a flat field, and excellent sharpness. Is there much of a difference between the celestron and haader? The Hyperions work well in SCTs and you can't beat that large eyelens and eye relief ,JMO. Edited April 23, 2010 by russ teh_orph Members 28 198 Author You really understood the material. Whether it is cars or telescope eyepieces, there are inexpensive ones, upgraded models, and very expensive ones. 130 mm scope will have a max of 260X for planning purposes. If that surface is wobbly the scope will be almost useless. We often end up spending more on eyepieces than we did on the telescope. Hi - I bought these from another AM'er 1 year or so back, thinking I will get into visual astro, But never found the inclination, So here it is for sale 9mm Nagler type 6 mint with box and caps,16mm Nagler type 5,optics are exc. While I also have the Baader Hyperion Zoom, mentioned later, I continue to make use of the Celestron, especially in my smaller scopes. Kellner eyepieces work perfectly with small and medium-sized telescopes. I usually recommend a 32 mm Plossl type eyepiece as that provides about the widest view you can achieve with a 1.25 focuser. I need some eyepieces with long FL for low magnifications. I really like the simplicity and compactness of these simpler designs (ie: Plssls, Orthos, Kellners, etc). Not really. It's no surprise that the eyepieces in our Sirius Plossl line are our best-selling telescope eyepieces. Ah I see what you are saying, I had wondered whether this might have had an impact as Ive seen it mentioned before but dont fully understand it so will do some research, thank you .

The more light that is gathered, the more magnification that can be applied to the image, up to the limits that are imposed by the atmosphere. Plossl eyepieces have an eye relief equal to about 80% of their focal length. Plossl eyepieces are typically used for observing and viewing things at long distances, but they can also be useful when using a telescope to provide both magnifying power and erecting the images. The Plossl's are very easy to modify, allowing me to use the bino-viewer on, all my refracting telescopes without having to cut down the tube length, p.s. Plossl eyepieces are great. This is where the cheap eyepiece will frequently fail to deliver a good image, around the edges. This can be especially helpful in telescopes of focal ratios below F8. These eyepieces have about 35 to 50 degrees apparent fields of view and reasonable eye relief, though quite short for high magnifications. She has been looking at the sky for years and hopes to introduce more people to the wonderful hobby that is astronomy. Tip Its almost always cheaper to buy directly from Agena Astro. Major telescope brands such as Celestron supplies Kellner eyepieces with their r least expensive telescopes and still may. The Plossl design has become the mainstay of the modern ocular business and probably represents the best value in terms of performance and price, especially in medium and long focal lengths. These companies rebranded them under their own names. All of the Omni eyepieces have a 1.25" barrel size with the exception of the super low power 56 mm, which has a barrel size of 2". I would recommend the Baader Hyperion Zoom for any telescope. Worth it is a tough question to answer. What focal length eyepieces should I buy? Yes, the wider field of view of a Plossl is very helpful, but 40 degrees of Kellners isnt a soda straw (unless you are used to looking through very wide field eyepiece. Plossl eyepiece is one of the reasonable options when it comes to telescope eyepieces for stargazing or astronomy. The Plossl eyepiece has 4 lenses, consisting of 2 identical double lenses. Consider something between 35 and 40 mm in focal length with an AFOV of 65 degrees or wider for your lowest power eyepiece for your telescope. I often recommend the 2 in this series as excellent low-power wide view eyepieces, especially in scopes at focal ratios below F8. Recall that your lowestpower eyepiece's exit pupil should not exceed 6mm. These lenses are connected together. This can be very helpful for star hopping. 70 mm scope will have a max of 140X for planning purposes. Stargazing Help is a participant in Amazon Associates program. But are they really? These eyepieces are technically called Symmetrics, since Plossls can have different focal lengths for each doublet, but they are always marketed as Plossl. I am very interested in viewing Nebulae do you think this set up will work well for that or do I need other eyepieces or filters? Can you suggest the total . . With modern multi-coated optics that thwart internal reflections, Plossls and Kellners have little difference in glare or transmission/opacity. I often recommend the use of a barlow to achieve the higher range of magnifications. Now we just divide it up and fill in some sample focal lengths. Your eyepieces do not need to be the same brand as your telescope. We also joined our local Astronomy Club and look forward to joining others under the night sky when the opportunity presents itself again. I often recommend it. If you wish to find a short-focal length eyepiece with a longer, more comfortable eye relief, you could use a long-focus eyepiece with a separate, high-quality barlow lens (an achromatic or apochromatic fully multi-coated barlow would be necessary), or you could purchase one of the several designs incorporating a smyth/barlow lens into the eyepiece design. Once we are done, they will make sense. Orion SkyQuest XT8 Intelliscope Review Plossl eyepieces have wider fields of view than Kellners. Aspheric eyepiece is a variation of Plossl design, it has an anti-reflection coating on the front glass surface to ensure maximum light transmission and will also provide your instrument with better quality images if you need higher magnification levels. Second? Was $38.99 - $99.99 Now $31.19 - $84.99 Compare Orion Edge-On Planetary 1.25" Eyepieces It costs a lot to get that last 10% of performance.
