As we continue, what would you recommend adding first? Recall that your lowestpower eyepiece's exit pupil should not exceed 6mm. Higher values are slower and lower values are fasterthis is a holdover from camera lens terminology and has to do with exposure times.). In my scopes a simple zoom eyepiece like the Celestron 24-8mm or the Baader has replaced the higher powered plossls. These eyepieces have about 35 to 50 degrees apparent fields of view and reasonable eye relief, though quite short for high magnifications. Aspheric and Plossl Plossl are both lens designs that can be used in most telescopes. . We enjoy binoculars for the moon, but having never looked through another telescope, my kids and I do not know what internal reflection, ghosting, vignettes, or diffraction spikes look like! The components of a Plossl eyepiece are the two groups of lenses. Celestron - 1.25" Eyepiece and Filter Accessory Kit - 14 Piece Telescope Accessory Set - Plossl Telescope Eyepiece - Barlow Lens - Colored Filters - Moon Filter - Sturdy Metal Carry Case.

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. With an f/10 telescope, Plossls are as sharp as any other kind of eyepiece of the same focal length. This was very useful, I got a meade infinity 90mm ( after read the review here -. Some accept 2 and have an adapter that allows you to also use 1.25. And I am a visually observing focused person. Scott. On many occasions, that will be too high power for the atmospheric conditions. Your eyepieces do not need to be the same brand as your telescope. It also was considerably more expensive. No, adapters are not needed but they may come in handy when you want to change the focal length or add other lenses such as filters or Barlow lenses. But your point is well taken. This has nothing to do with your scope or eyepiece. Brilliant article and I thank you for it, I was literally really confused prior to reading it. This is not a hard and fast rule, just a cautionary note. If you are buying your first telescope, and you are choosing between the telescope that includes a Kellner or a telescope that comes with a Plossl, with all the other specs being similar, pick the telescope thats offering you the Plossl, even if its slightly more expensive. To determine a magnification range, we will start with the aperture of the telescope, the size of the front lens, or the mirror in the back. - 32mm plossl. The larger barrel allows them to create an eyepiece with a higher AFOV. The Big Bang Optics is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.

Within the budget-friendly realm are the 6mm and 9mm Goldlines/Redlines (66-degree Ultra-Wide-Angle) for telescopes with a focal ratio of f/8 or longer, and the excellent 58-degree Planetary eyepieces, sold by a variety of sellers on Amazon and by Agena Astro, which come in a wide variety of focal lengths and are optically superb for their price. Even though there are more sophisticated types of EPs, Plossls hit the right spot between high-quality optics and price. It should list what size eyepieces you can use. In some cases, the eyepieces are waterproof to protect them from internal contamination caused by heavy dew conditions. Does this sound like something you would recommend based on the telescope I have? Lets give an example. Goldline series of eyepieces provides the best value in this price range, better than Plossls. https://telescopicwatch.com/celestron-8-24mm-zoom-eyepiece-review/. 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. i still use the binos. Orion Sirius Plossl eyepieces are ideal for any type of telescope; refractor, reflector, or catadioptic. However, Orion has managed to make one that is quite compatible with most styles of telescope. I started with the Celestron zoom. This means you will be able to see a greater expanse for the objects in space but with fewer magnification levels than Kellner or Plossl lenses. A typical zoom eyepiece has a focal length range of 8 mm to 24 mm. I dont own nor have I used it, but Orion has a very good reputation. Also, note that the pricing is based on 1.25 eyepieces. It is as simple as that. What happens if you use an eyepiece that has a the wrong exit pupil? I am considering buying another eyepiece, maybe 6mm, and a Barlow, maybe 2x, to give me a wider and higher range of magnification.

You use the 8-24 zoom for the midrange. This Super Plossl design was better than regular Plossl eyepieces, but not by much. Now we have a maximum established. Many thanks. Question: would it perform well with 1.5/2x and 3x Barlows? As a kid, I loved looking at the moon (which can be seen any time of day, regardless of ones bedtime) so make sure that the field of view is wide enough to see the whole shebang. Compared with a zoomable telescope eyepiece, they are pretty much the same in terms of the quality of the image. I like my 38/70. Astrophotography with Nikon D3200: Can It Be Better? A key thing to remember is that eyepieces are universal. We can see that 2 eyepieces have an advantage over 1.25 eyepieces when designers are making wide-view eyepieces. I have CPC 925 and I currently own Hyperion 10mm, Hyperion 17mm and Celestron plossl 40mm. I often recommend the use of a barlow to achieve the higher range of magnifications. If you read the article you know how to calculate the magnification and field of view. I guess my curiosity is mostly about the diagonal. Is there anyway you could include links to the eyepieces you mentioned in the last paragraph of your reply as Im totally new so worried about buying the wrong thing! There are many more designs that are associated with specific brands, but the ones above are designs that are produced by many companies in one form or another. 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. However the package includes a 1.25 to 2 adapter so if you have a 2 focuser you can treat this like a 2 eyepiece leaving the adapter normally included with the scope for use with other 1.25 eyepieces. To achieve six magnifications, you can have six eyepieces. Some optics brands have taken the next step and launched some eyepieces they have labeled as Super Plossl. By having a range of magnifications, you can optimize the image, which means you need more eyepieces. 17mm Plossl, unbranded, used, no caps, in bolt case; previous owner said it was a very good EP; $18 25mm Plossl, Orion Sirius, fully MgF2 coated on every air-to-glass surface; used; $23 (these are a step up from .

At that price point, it couldnt compete with other 5-element devices like Erfle and Nagler eyepieces that had better performance. The zoom can be used with any 1.25 focuser too. Your email address will not be published. How do you focus - I would have expected helical focusers in the eyepiece holders but don't see any? I have seen some gatekeeping in this hobby about Kellners, and Im not sure I understand it. Theres a reason Plossls are usually kept at 52 degrees.

As for Barlow Lenses, take a look at this article. In this article, we will only focus on the differences between Plossl and Kellner eyepieces. The Japan made 16mm Meade 3000 was a very nice medium power plossl and the 40mm in that series was surprisingly nice as well. But, if you have a plan, you can fill in those slots, working toward a well-balanced set of magnifications. In the early days of telescopic astronomy, refractor telescopes were designed with a single lens at the front and a single lens at the back.

A Televue Plssl may be better than a generic one, but the difference is probably not worth the additional cost. 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). I think you will love it! condition as described, a good transaction. We have compared Plossl against Kellner eyepieces in a previous article. I would recommend the Baader Hyperion Zoom for any telescope. I have just one Meade product currently and that is a series 4000 1.25 inch UHC type filter which I use for outreach. But some people demand the very best, and it is available, at a price. This type of design provides for both total magnifications as well as an erect image with little distortion. They also improve a bit when it comes to eye relief. dnrmilspec is right. The Baader offers wider fov, but at quite the price premium. Lenses are fully multi-coated for excellent light transmission and reduced internal reflections. I dont think so. Of course, the entire eyepiece must be manufactured and finished correctly to realize the design's full potential. For astronomical observations, such as viewing craters on the moons surface from Earth, high-magnification models are preferred because they offer more detail. One learns by observing. This would definitely matter to observers who wear eyglasses when viewing. The Wiki article(s) were very good if anyone else is confused.

Hi Ed, A Plssl is probably as good as any 32mm eyepiece in a 1.25 inch focuser. While eyepieces with relatively complex, proprietary, or bespoke designs are becoming more commonly available in the beginner price bracket, there is often good reason to choose a much simpler design. Best suited for telescopes with f-ratios f6 or slower. I agree. If you are upgrading, avoid ones that say correct image as these add a prism system into the diagonal which can reduce the light transmission. Even though the design has existed for more than a century, it has stood the test of and is still today the standard against which other eyepiece designs are measured. So your 600 mm example (f/6) becomes, in effect, an 1800 mm focal length, f/18 but it does not change the focal length of the eyepiece. How Good Are Super Plossl Eyepieces for Astronomy? Kellners can be as little as half the price of a Plossl in the same focal length, but they are generally very comparable, especially in recent years as telescope prices have fluctuated in response to changing supply chains and demand.

Youd have to look into more complex designs which include a barlow lens, or simply use a longer focal length eyepiece with a quality barlow. I often recommend the 2 in this series as excellent low-power wide view eyepieces, especially in scopes at focal ratios below F8. I have Celestron and the Baader Hyperion. It's no surprise that the eyepieces in our Sirius Plossl line are our best-selling telescope eyepieces. 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. It also produces an erect image, meaning you see what youre viewing rather than seeing everything upside down or sideways as some types do. Heres the short answer Plossl eyepieces are generally better than Kellner eyepieces, but they also tend to be more expensive. That's how cost-efficient the entire package is!

They are just OK, but I dont recommend them, especially in a low focal ratio scope. Focus on the magnifications rather than the mm of the eyepieces. So yeah, they are good.. and some are even better than others, and more collectible. Gold line eyepieces are available in 6mm, 9mm, 15mm, and 20mm focal lengths. Generally, to maximize the number of stars you see in an eyepiece with a given telescope, both the magnification and field of view should be maximized. Eye relief is the distance from the eye lens to your eyeball, and the higher the better (within reason). In my opinion, you do not. They also offer a generous 16 mm of eye relief which is most important in the shorter focal lengths. Magnification or power = focal length telescope / focal length eyepiece, Focal ratio = focal length telescope / aperture telescope, maximum practical aperture = aperture X 2, Edges of the optics are blackened for increased contrast, which prevents internal reflections, Anti-reflection, fully multi-coated optics provide enhanced light transmission for bright and clear images. Optics manufacturers began selling and popularizing Plossl eyepieces, albeit with a generally simplified design where each achromatic doublet had the same focal length. Modified vs Unmodified DSLR Astrophotography: The Ultimate Showdown! Thanks in advance I really appreciate it! That is up to you and your budget. As you saw in the article, they eyepieces that would be best for you, or your child, is based on your budget and what your goals are.

The longer FL Plossls (>15mm) have some distinct advantages over more complex designs without the major disadvantage of Plossls which is short ER. My Meade 4000 56 and 60 degree Meade Plossls are pretty sharp to my eyes and do pretty well for me. The TFOV will be as wide as your 40mm Plssl, but with greater magnification and a slightly darker sky background. Which is Stronger? Plossl eyepieces have wider fields of view than Kellners. Note that many cheap eyepieces promise a wide AFOV but deliver a view with a lot of distortion or aberration as you move away from the center of the field of view. As we go along, I will refer back to these, so dont worry if you cant answer the questions or understand the formulas now. I do not miss beating my eyelashes against a 9.7mm Meade Plossl that I used to own. SV207 30mm Super Plossl Eyepiece. but the meat of the article is about understanding the considerations and specifications to know when selecting eyepieces.
