are plossl eyepieces good

Many thanks. Hi Ed, These eyepiecesproduce a 'standard apparent feld of view' of between 50 and 56 with most set at around 52. I generally use my 40 to search for DSOs so Ill probably replace that one at some point too. The larger barrel allows them to create an eyepiece with a higher AFOV. These low-quality Plossls lack an internally blackened lens barrel with thread baffles and blackened lens edges and sophisticated anti-reflection multi-coatings, all of which are a necessity to produce an excellent image. Note that we also gained a 16 mm magnification at no additional cost. My Barlow is a 2X with a removeable Barlow element that can be screwed right onto an eyepiece giving a 1.5X effect. And, the quality of the eyepiece clearly comes into play here. condition as described, a good transaction. Im fairly picky so would extend budget for better eyepieces if its worth it. For one thing, a wider field of view is almost always more pleasant. philhas Members 61 459 Location: North East England But these are only intended to get you started. I would like to know what is best for a 7 year old that would be getting his first telescope. It is all about your budget, your goals, and your objectives, as outlined in the article. Understanding and using a Barlow Lens The magnification range that is appropriate to your scope. Worth is a subjective evaluation, so here is my subjective input: 1. I dont have a specific diagonal to recommend and I am not aware of any specific issues with the one that is included with the scope. In my scopes a simple zoom eyepiece like the Celestron 24-8mm or the Baader has replaced the higher powered plossls. Now we have a maximum established. It appears to be a custom-made 90 degree binocular built from two 90 degree diagonals and binocular-size objectives attached in place of the usual OTA. These will normally be higher priced and may be outside the price range we show here. The basic design hasnt changed much, but the real costs of manufacturing have dropped. 8.5-ish mm (75x & 150x) In some cases, an object is so large (i.e., the Moon, the Pleiades, the Orion Nebula, the Andromeda Galaxy) that a narrow field of view can only show you part of the object, whereas a wider field of view could show the whole object at the same magnification. Then you can judge for yourself if it is worth it. What Does It Do. Kellner eyepieces use three glass elements in two groups to minimize color fringing. 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). This SVBONY eyepiece review should get you up to speed with the budget stargazing options. It doesnt matter what type of telescope you have, as long as your scope takes these standard sizes. There is no problem using a Celestron eyepiece in a Meade telescope, for example. The price ranges we show here are the typical prices. Customer reviews Average Rating (16 Reviews): Write a Review and share your opinions! My other eyepieces, ES and Meade 82 degree, stayed in the eyepiece case most of the time. Also, note that the pricing is based on 1.25 eyepieces. These are exceptional eyepieces, and only available on the used market nowadays. All focal lengths offer 50 field-of-view except the 40mm which offers 42 Those are significantly more expensive than the 1.25 focal lengths. However, Orion has managed to make one that is quite compatible with most styles of telescope. Well-made lenses are expensive though, so in general the more lenses, the higher the price of the eyepiece. short answer: yes. Why not go back to the people who sold you the scope and get their help. We will now discuss the specifications of eye relief and apparent field of view. Apparent Field of View: This is a measure of how wide a view the eyepiece will provide as compared to alternate eyepieces. Most likely it will be used as a loaner eyepiece to go with one of my two loaner telescopes. is pretty forgiving of eyepiece faults and a wide variety of eyepiece designs will work just fine in it. Once I knew how much I liked the zoom I upgraded to the Baader Hyperion Zoom. It is pretty much worth it for everyone that has a telescope with a 1.25 inch focuser to have a 32mm Plssl. These are often compared to the higher priced offerings. You can still get eyepieces, but there are few choices. no caps come in bolt case. Look those up, seeing and transparency in the context of astronomy. Number of Lenses. You noted eye relief is important for those wearing glasses. Even though both eyepieces are very common in beginner telescopes, it has become harder to find Kellner eyepieces on their own in the last two years, whether they come from a brand name or the original equipment manufacturer or a reseller. Not all are Plossls, but excellent eps at f/10. I dont know if they make anything like this anymore, but as a kid, I had plastic slides with images on them (the Milky Way, Horse Head Nebula, etc.) I foolishly destroyed it while experimenting with solar projection, because I hadnt realized the metal-and-glass construction was aided by a plastic retaining ring on the field stop, and I hadnt realized you do not need to change the eyepiece focal length when doing solar projection. I have an SCT and my eyepiece case only hasPlssls (and one Ortho) in it. 1:10 . Kellner and Plossl- both are two different types of eyepieces for telescopes. Sirius Plossls offer a 52-deg apparent field of view for clear, sharp images. Thanks all. 2. The field of view of the eyepiece has a few effects when it comes to actually using it in the telescope. Can You See The ISS With A Telescope? This design has some advantages over other designs, such as the Kellner eyepiece or Orthoscopic eyepieces. If your focuser/diagonal will accept 2 eyepieces, then I will suggest you get one or two 2 eyepieces for your low power wide view eyepieces. I want these as possible as wide, magnification and astrophotography purpose. It may very well last you a lifetime and in the long term, you will definitely consider it to be a worthwhile investment. Even though there are more sophisticated types of EPs, Plossls hit the right spot between high-quality optics and price. For astronomical observations, such as viewing craters on the moons surface from Earth, high-magnification models are preferred because they offer more detail. Some will offer longer eye relief which can be important to eyeglass wearers. I've got a one-off plossl like that in my kit that I'll probably never sell, (aside from my 5 element ones) and it's one that is rarely seen. Like going from a 32 TV to a 65? These sizes have become the industrys standard sizes. When selecting the best eyepiece for you, consider: Eyepieces are standardized so whatever investment you make today, the eyepieces will continue to serve you in any future scopes you may own. No surprise there. As for tabletop scopes, dont forget that you need a table, stool, or bench to place them. I have four telescopes, but I use the same eyepieces in all of them. The computerized pad and motor work on AA batteries which can last you a few hours. However, because they have more glass elements than other designs, like Kellners, their manufacturing becomes extremely important to get high-quality optics. The Plossl was also called a Kellner Type III in some earlier references; in the 1950's, Edmund Scientific sold a "Kellner" eyepiece made from war surplus lenses, but it actually consisted of two achromats in the classic Plossl configuration. The Plossl is a good all-around eyepiece design, is well suited for generic use and is relatively inexpensive to make. My 20, 26, and 32mm Plossls will probably stay around. Since there are so many different types of eyepieces available on the market, choosing the right one for your situation can prove to be a harrowing task. It had one of the best fields, edge to edge, in my SCT that I've ever seen. On many occasions, that will be too high power for the atmospheric conditions. Over time, you may wish to add a specialty eyepiece here or there, but I would not make that a priority until you have filled out your magnification range.

Astrophotography with Nikon D3200: Can It Be Better? Comparing to Plossl, the Expanse eyepiece is a lot more expensive. I am not aware of any such solutions for Newtonian reflectors. If you don't like the reflections, there really aren't many other budget options at its focal length beside a Plossl which will be super uncomfortable to use, or spending over $100 for something like a Meade UWA. The one exception I would keep in mind would be when working with Newtonian reflector telescopes below F5. There are inexpensive adapters that will let you use standard 1.25 eyepieces in a .965 focuser/diagonal. I believe the 5000 UWA's are good as well. Omni 40mm Eyepiece - 1.25" Learn More. 3. My love affair with space began in a field in India at the age of 7, when I looked up at the Milky Way for the first time. I have seen some gatekeeping in this hobby about Kellners, and Im not sure I understand it. Then there is a pair of 32mm and 20mm TV Plossls which make my binoviewers work well with a Daystar Quark H-alpha solar filter. They also improve a bit when it comes to eye relief. If we combine a Barlow with an 8-24 mm zoom eyepiece, we have an amazing range. Sooooo helpful! They have decent eye relief and little curvature of field. I currently own a Mak127 ( that can't use 2"eyepieces) and a 80ED ( that one can hold 2"eyepieces). 4mm Eyepiece vs 20mm Eyepiece. In my opinion, there are no wrong exit pupils. there are of course options to plossls which are about the same prices as GSOs such as the BST Discoveries and TMB type eyepieces (new from Skies the Limit on Ebay) which have a wider field and better eye relief than plossls and are probably as good as most things non-premium. Higher than 3X is usually reserved for astrophotography. But your point is well taken. Some brands will add better lens coating, darker edges, or a higher quality case to their Super Plossl products, but strictly for performance, there isnt a difference between the two. A Plssl is probably as good as any 32mm eyepiece in a 1.25 inch focuser. Are Plossl eyepieces good? I think you will love it! So, basically a Plossl eyepiece is a type of eyepiece that enables the viewer to see a wider field of view than would normally be the case, but at the cost of him/her having to physically put his eye very close to the lens of the eyepiece. Explore Scientific 68 34 mm or ES 82 30 mm would also be good choices at a significantly higher price but with better edge correction. The longer FL Plossls (>15mm) have some distinct advantages over more complex designs without the major disadvantage of Plossls which is short ER. The original Meade 5-piece Super Plossl hasnt been in production for decades and at this point is more of a collectors item than a high-performance eyepiece. NEW. IF you like your Hyperions , you could get a 2 inch visual back and 2 inch diagonal / or 2 inch SCT diagonal and add the 31 or 36 Baader eyepieces in 2 inch . Orion Sirius Plossl eyepieces are ideal for any type of telescope; refractor, reflector, or catadioptic. the reality is that today's eyepieces are all quite good, particulalarly in an f/10 telescope. My Baader Hyperion Zoom is my most used and favorite eyepiece. A Plossl eyepiece is one of the most decent general-purpose eyepieces that are available on the market. I loved my Baader Mark-IV 8mm-24mm Zoom+Barlow combo in my 8" EdgeHD. You could say Super Plossls are not much more than a marketing tactic these days. Nothing will stop you from trying to go higher, but in all likelihood, the image will be poor and not worth the cost of eyepieces to achieve it. A Kellner eyepiece has 3 lenses, while a Plossl has 4. I use some plssl eyepieces, since I still have quite a few in my kit, and yes, the others are correct. the shorter the focal length eyepiece = the shorter the eye relief. However, you may see them at higher prices for the short term. Some optics brands have taken the next step and launched some eyepieces they have labeled as Super Plossl. Fully coated with magnesium fluoride on every air-to-glass surface for excellent light transmission and high contrast views. So we say that an F5 scope benefits from better corrected eyepieces more than the F10 scope. If one Super Plossl specifies it uses a 5 lens design, then you can definitely consider it a true Super Plossl that might offer better performance, but no brand has released any of those for decades. I have personally tested a few Super Plossl and compared them to their regular counterparts by the same brand. These companies rebranded them under their own names. Do you need to have the best to enjoy astronomy? This series of eyepieces may provide better value in this price range. Most modern telescopes use a focuser, or diagonal, that accepts 1.25 eyepieces. As I mentioned earlier in the article, not all Plossls are created equal, which simply means that there are good Plossls and then there are bad Plossls. It's one of the best choices you have when it comes to budget stargazing. Oh the pain of uh having access to really cool eyepieces.). And you don't even have to get the full set if you don't want to. In the beginning, you are not going to know what the atmospheric conditions might be in your area. A zoom eyepiece works like the zoom lens on a camera. Simple Plosels work well and unless you have money burning a hole in your pocket, I would start with simple affordable eyepieces. However, i can read very well without my glasses with almost microscopic vision and can use my binoculars without glasses. Looking from different sorts I found the Baader Aspheric 31mm and 36mm.these two eyepieces allow me to switch between 2" and 1.25"just by changing the barrel. Would a higher magnification eyepiece help do you think or am I already pushing my telescope (XT8) to highest sensible magnification I can with BH zoom on setting 8mm and 2x Barlow? A rubber safety cap protects the lens when not in use while also providing additional grip on this 35 mm Plossl eyepiece. A standard Plossl eyepiece is typically between 20mm to 25mm but can range anywhere from 15mm up to about 40mm in diameter. With modern multi-coated optics that thwart internal reflections, Plossls and Kellners have little difference in glare or transmission/opacity. At least you'll have one budget eyepiece that will give you a larger part of the sky at low magnification. For example, if you put a 30 mm eyepiece in a 3X Barlow, it will triple the magnification you get from that eyepiece. Between Kellners and Plossls, this means a 32mm Plossl, which maximizes the field of view in the 1.25 barrel diameter format, will show more stars than either a 32mm Kellner with the same magnification but a smaller true field of view, or a 40mm Kellner (or 40mm 1.25 Plossl, which has a 40 degree apparent field of view) with a lower magnification and the same true field of view. High-quality Plssl eyepieces provide high contrast and sharpness across the entire field of view. The Plossl eyepiece has 4 lenses, consisting of 2 identical double lenses. I expect such eyepieces are available but I have never seen or used one. They can also be found as Orion Expanse sporting a blue line rather than gold. I also have an older smoothtop 20mm Meade 4000 that is also 5 element, and it is a fine eyepiece too, compared to another 20mm of the same vintage. You can find the eyepieces I use and recommend in this article. Note to spectacle wearers: Plossl eyepieces with 15mm and longer focal lengths are good choices for spectacle wearers but for shorter focal lengths the Celestron XCel LX series have greater eye-relief so are better suited. You might be able to find a Kellner, or perhaps a high-quality Orthoscopic. The eye relief is the distance between your eyes and the eyepiece where you are able to view the whole image comfortably. I often recommend the use of a barlow to achieve the higher range of magnifications. If you are just testing the waters or on a tight budget, get the Celestron, which is still pretty good. Kellner eyepieces were first designed by Carl Kellner in 1849. 130 mm scope will have a max of 260X for planning purposes. Most people will be fairly comfortable with eye relief of 12 mm or higher. Theres a wide range of quality when it comes to Plossls and trusting the brand you are getting one from matters a lot if you dont want to get an eyepiece with lots of reflection or optical issues. The big problem with Plssls is that the eye relief is about 0.75 times the focal length. Read the full Earning Disclosure here. Lets illustrate with an example using a 1200 mm FL telescope. Which is Stronger? I do not miss beating my eyelashes against a 9.7mm Meade Plossl that I used to own. Fortunately, the investment can be leveraged with future scopes since eyepieces are standard sizes so they work in almost any telescope. Save my name, email, and website in this browser for the next time I comment. In our example, we targeted 200X as the top magnification. Come join the newest, most engaging and inclusive astronomy forum geared for beginners and advanced telescope users, astrophotography devotees, plus check out our "Astro" goods vendors. They also offer a generous 16 mm of eye relief which is most important in the shorter focal lengths. I recommend it often to beginners on a tight budget. ORION SIRIUS PLOSSL 10mm telescope eyepiece 1.25" - $17.01. Scott. I have CPC 925 and I currently own Hyperion 10mm, Hyperion 17mm and Celestron plossl 40mm. That is a wonderful expression. It's no surprise that the eyepieces in our Sirius Plossl line are our best-selling telescope eyepieces. 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. 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. No price limit? . Also, as the apparent field of view gets wider, the image will require more correction. 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.). Compared with a zoomable telescope eyepiece, they are pretty much the same in terms of the quality of the image. Are plossl eyepieces still worth it? I must say Im quite confused about eyepieces. Quality this good usually costs a lot more. Ever since, I have been attempting to cram in every fact about the Universe, I can find into my head. Here we have very good eyepieces with some extra features. PS. The design of a Plossl eyepiece consists of an objective lens with one side that is convex (wider than its length) while the other side is plano-convex or flat in shape. I have several 10mm eyepieces in my eyepiece boxalmost all of them are eyepieces that came with some telescope I boughtand I will almost always choose to use one of the Kellners over one of the Plossls, because the Kellners have a longer eye relief, which is comparable to the focal length. The image quality is very good and the additional field of view and longer eye relief makes them very comfortable to use. https://telescopicwatch.com/best-astrophotography-telescopes/. I still use my 30mm Celestron Ultima fairly often with some of my telescopes. 2019-2023 Little Astronomy. Plossl eyepieces have a wider field of view that can go from 50 to 56 degrees. In that respect, they are similar to the Explore Scientific 82 degree mentioned earlier. With your glasses on, you simply cant get your eye close enough to an eyepiece that only has 10 mm of eye relief. How important a consideration is this when deciding on an eyepiece? And the zoom provides every magnification in that range without having to change eyepieces. 1.25" 6.3mm 32mm 40mm Plossl eyepiece set give you a good variation in magnification for a wide range of targets with extra sharpness and long eye relief. Hi, I have recently bought a Orion XT8 and am trying to work out which eyepieces to add to what is provided with the scope. Celestron 2026 Erecting Prism Barlow Lens Set is well suited as an astronomical viewing lens kit or for enjoying terrestrial sights like nature walks, sporting events, and more! 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.
