Gosky 1.25inch Plossl Telescope Eyepiece - Amazon.com If your telescopes focal length is different, just change the focal length in the formula. This eyepiece was even better at correcting false color fringing, but because of internal reflections, the glare was even worse. I also really liked my E-Lux 32mm, a Kellner. 6mm Kellner eyepiece that I enjoyed a lot. This is your Lexus, Acura, and Infinity types that offer more features, better build, and a bit more polish. But in this scope, the 32 mm doesnt work well. 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. The basic design hasnt changed much, but the real costs of manufacturing have dropped. . The Plossl eyepiece has 4 lenses, consisting of 2 identical double lenses. In terms of eyepieces, my best advice is provided in the article. Divide that by the magnification of that eyepiece in that scope. The eye relief is the distance between your eyes and the eyepiece where you are able to view the whole image comfortably. The Baader offers wider fov, but at quite the price premium. I was looking on a OPT website and they have celestron 32mm and 15mm plossl. 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. See if you will observe with or without your glasses. They also offer more eye relief than Plossls at the shorter focal lengths. These companies rebranded them under their own names. All the rest will likely be 1.25. Well, I'll just say it. These eyepieces have about 35 to 50 degrees apparent fields of view and reasonable eye relief, though quite short for high magnifications. Thank you so much for taking the time to provide all this information! This might contain more of what you need. You can build a full set of these with good results, but be aware of eye relief, especially if you wear glasses. If you look up transparency and seeing in the context of telescopes you can learn more about how atmospheric conditions will affect what magnifications you will choose on any given night. Though not the Meade. Also, note that the pricing is based on 1.25 eyepieces. https://telescopicwatch.com/best-astrophotography-telescopes/. We are a team of active amateur astronomers, here to help you with all your astronomy and science related needs this is anything, from reviewing the latest telescopes to be released to talking about gravity and neurons. You can read a thorough review of Goldline eyepieces here. 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. And I continue to read excellent reports on the AT Paradigm and similar under different labels. still, i somehow managed to avoid the eyepiece pitfalls when buying used off ebay. Hi Ed, https://telescopicwatch.com/orion-skyquest-xt8-intelliscope-review/. Plossl eyepieces are very good and fairly inexpensive, typically between $25 and $50 each. Using your example: We will use a 100 mm telescope with a 600 mm focal length and Another way to look at it is that a 30 mm eyepiece in a 3X Barlow works like a 10 mm eyepiece.. I have had a good experience with the SVBony brand and the Agena Astro brand. Although Kellner eyepieces will help you learn a lot in the beginning but soon will realize that youre missing out on something, and eventually you will be tempted to spend money on another good quality eyepiece. For one thing, a wider field of view is almost always more pleasant.
Telescope Eyepieces Guide - High Point Scientific But what are the differences between these two and how do you know which one to choose? To achieve a maximum of 200X (2X the aperture of 100 mm), we solve for the focal length. If we look at the range I provided above, we see that we could replace several eyepieces with one zoom. 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. . You can accomplish a longer eye relief by barlowing a longer f/l plossl, so that is something to think about as well. I dont think so. On many occasions, that will be too high power for the atmospheric conditions. 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. The 4000 SWA's were way overpriced for their performance IMHO. Outstanding job Jack. If you do choose to go with a Plossl eyepiece, I highly recommend spending some extra cash to get yourself a decent good quality branded Plossl eyepiece rather than going for a cheap, generic eyepiece which is a Plossl only for the namesake.
Good quality plossl eyepieces - Discussions - Stargazers Lounge It has made learning the Constellations and star-hopping more fun and engaging for my whole family exactly what I was hoping for. Using this 40 mm Plossl eyepiece is an excellent way to get a wide field of view with your telescope. 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. 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. 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. Poorly chosen eyepiece might give you poor experience and sometimes even make stargazing difficult. Any 1.25 eyepiece will work with the BH Zoom 2 adapter. Plossl eyepiece is one of the reasonable options when it comes to telescope eyepieces for stargazing or astronomy. They provide a range of magnifications with one eyepiece. However, if you want to optimize your viewing experience, youll need to invest in a better-quality eyepiece. These are often compared to the higher priced offerings. These have the advantage that the front section with the optics can be unthreaded and threaded on to the filter threads of a 1.25 inch eyepiece. I would expect it to be similar to the Celestron in image quality. Plossl eyepieces have a wider field of view that can go from 50 to 56 degrees. The Hexagon Zoom Eyepiece is made from durable plastic material that resists scratching and it has an eye relief distance of 15mm. It is pretty much worth it for everyone that has a telescope with a 1.25 inch focuser to have a 32mm Plssl. Thanks for going through the entire post. 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. The ocular for your highest visual acuity - for viewing deep-sky objects and the like - should have an exit pupil around . The larger barrel allows them to create an eyepiece with a higher AFOV. You are asking about a very specific eyepiece in a very specific scope combined sometimes with a Barlow. This eye piece provides the maximum true field of view in the 1.25 inch format. With your glasses on, you simply cant get your eye close enough to an eyepiece that only has 10 mm of eye relief. Generally, Plssl eyepieces are best suited to Newtonian and fast telescopes. If you are going to wear your glasses when you observe, you want at least 18 mm of eye relief and 20 mm is better. Here we get into the BMW, Cadillac, Porsche, and Ferrari of eyepieces. Even if we were next-door neighbors this would take weeks of discussion and planning.
Orion Sirius Plossl 1.25" Telescope Eyepieces The only difference is that they have a different design as well as a shape with their lenses, which affects the magnification of your telescope view. Higher than 3X is usually reserved for astrophotography. If I had to give them all up and keep only one eyepiece, It would be the BH Zoom. I still have it and still use it from time to time. The only reason it's in this list because of its price and a long focal point. How important a consideration is this when deciding on an eyepiece? I have just one Meade product currently and that is a series 4000 1.25 inch UHC type filter which I use for outreach. Stargazing Help is a participant in Amazon Associates program. Other than the limited AFOV, which you are apparently fine with, and limited eye relief in the shorter focal lengths there is certainly no reason not to choose Plssls.
Vixen NPL Eyepieces | First Light Optics Ive read, and re-read, and re-re-read this page. Was $38.99 - $99.99 Now $31.19 - $84.99 Compare Orion Edge-On Planetary 1.25" Eyepieces They are usable, but your eye will be extremely close to the top lens glass. Omni 40mm Eyepiece - 1.25" Learn More. that I could slide into my telescope and look at. Thus the 30 mm eyepiece in a 600 mm telescope produces 600/30 = 20X magnification while with the Barlow, we have 1800/30 = 60X. 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. A Barlow lens is an optical device that goes between the eyepiece and the focuser. Glad you found it helpful. The price can run to over $1000 per eyepiece. The combination of high-quality optics and accessible prices have made them the favorite design for amateur astronomers and even professionals. I have CPC 925 and I currently own Hyperion 10mm, Hyperion 17mm and Celestron plossl 40mm. They have a pop-up eye guard and they are threaded to accept filters. 2019-2023 Little Astronomy. The field of view of the eyepiece has a few effects when it comes to actually using it in the telescope. I possess an embarrassing array of fine eyepieces with names like Ethos and Nagler and Delos. Question: would an 18mm Baader Classic Ortho mostly used for Moon and planets loose sharpness and contrast if used with a short F5 telescope like the Celestron Astro-Fi 130? Then you can judge for yourself if it is worth it. The tradeoff was that each lens surface added another internal reflection, reducing contrast and adding glare. This is the link to the one I plan to buy as I know some others come with add ons: https://www.rothervalleyoptics.co.uk/baader-hyperion-mark-iv-8-24mm-universal-zoom-eyepiece.html, Thats great you had an XT8i that makes me feel confident I got a good telescope .

Plossl vs Kellner Eyepieces: Which Is The Best? - The Big Bang Optics https://telescopicwatch.com/celestron-8-24mm-zoom-eyepiece-review/. And since this article is intended as an aid to beginners rather than a rigorous optics lesson, I think the context I provided works well enough. At shorter focal lengths they have less eye relief, and at all focal lengths they have a narrower field of view, than newer types. 6.7 = 268 = .3 Plossl eyepieces have 4 lenses that are paired in two doublets. - 32mm plossl. In my scopes a simple zoom eyepiece like the Celestron 24-8mm or the Baader has replaced the higher powered plossls. It allows each eyepiece to provide two magnifications. Just give yourself some time to learn the app and to understand the scope. You could say Super Plossls are not much more than a marketing tactic these days. 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). This type of eyepiece provides you with wide-field views without any distortion due to its use as an achromatic lens system which reduces chromatic aberrations by combining two lenses made from different types of glass materials together on each surface. Remember that visual and AP have very different requirements, so plan on at least two different optical tubes. I have owned wider eyepieces, but ultimately I just prefer the Plssls (must be a mental defect). We have a range of 32 mm to 3 mm. Comparing to Plossl, the Expanse eyepiece is a lot more expensive. 1200 mm FL scope / 10 mm FL eyepiece = 120X, 40 degree AFOV / 120X = .33 degrees (less than 1 full moon wide), 60 degree AFOV / 120X = .5 degree FOV (about one full moon with no space around it), 82 degree AFOV / 120X = .68 degree FOV (about one full moon with a star field around it to frame it). At one time Plssls were premium eyepieces. 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. Plossl eyepieces are often included in better telescope packages as the starter eyepieces. If you are investing for the future, get the BH zoom.

The availability of good quality relatively wide field-of-view inexpensive eyepieces has kind of put them in the second tier of eyepieces, but they still hold their own in the longer focal lengths and excel if one does not demand a wide field-of-view. 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! I still use my 30mm Celestron Ultima fairly often with some of my telescopes. Celestron's 4-element Plossl eyepiece features include blackened lens edges to minimize internal reflection and maximize contrast, fully multi-coated optics for maximum light transmission. But with 2 eyepieces and a Barlow, you have the full effective range of your telescope. As I discussed earlier, the zoom lets you explore your target over a wide range of magnifications without having to change eyepieces. is pretty forgiving of eyepiece faults and a wide variety of eyepiece designs will work just fine in it. Fortunately, the investment can be leveraged with future scopes since eyepieces are standard sizes so they work in almost any telescope. Even big telescopes are subject to limitations imposed by the atmosphere. 2x Barlow
Telescope Zoomable Eyepiece; Better or Worse Than Plossl did i pass? Meade went back to the drawing board and they removed the fifth element, keeping the original Plossl design, however, they kept the Super Plossl brand and added some premium materials. The BHZ 2 Adapter has threads on it so you can attach filters to it allowing you to use 2 filters with the zoom. 32 mm = 18.75X 16 mm = 37.5X (32 mm eyepiece with a 2X barlow), 12 mm = 50X (If you have a 25 mm that came with your scope, use Barlow for 12.5 mm), 4 mm = 150X (8 mm eyepiece with a 2X Barlow), 3 mm = 200X (6 mm eyepiece with a 2X Barlow), 24 mm = 25X (the low power end of the zoom), 8 mm = 75X (24 mm zoom setting in a 3X Barlow), 2.66 mm = 225X (8 mm zoom setting in a 3X Barlow), True field of view or FOV = Apparent field of view (AFOV) eyepiece / magnification. i did buy an astro-tech 3.2 paradigm ed from a cloudynights.com forum member. I have the 38 mm and recommend it often. Sooooo helpful! I think you will love it! 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. Focal length telescope / focal length eyepiece = magnification or power.
Astro Essentials Super Plossl Eyepiece | First Light Optics I also like to have my face physically in contact with the eyepiece (or the eyepiece cup) so the tight eye relief of the shorter focal lengths actually works really well for me. I couldnt find any suggestions on your site about diagonal recommendations. It also produces an erect image, meaning you see what youre viewing rather than seeing everything upside down or sideways as some types do. 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'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.
TeleVue Naglers, Plossl and Powermates | Astromart Whether it is cars or telescope eyepieces, there are inexpensive ones, upgraded models, and very expensive ones. Because the eyepiece was still similar enough to a Plossl and still kept the symmetrical design, they called it Super Plossl. I want these as possible as wide, magnification and astrophotography purpose. Good 32mm Plssls run around $30-$40. They work great every day and get you where you want to go, but dont have what the higher priced models have. This is a good thing, because normally the shorter the focal length of the eyepiece, the less eye relief you have. I often recommend a 32 mm Plossl as a good low power wide view eyepiece for scopes with a 1.25 focuser. Do you need a 10 mm planetary and a 10 mm DSO eyepiece? A 32mm Plssl is worth it. This can be debated 100 ways, but that is my advice. A Kellner eyepiece has 1 double lens and 1 single lens. Edge sharpness is just satisfactory, nothing to boast about, as is the apparent field of view. That said, I should also tell you that not all Plossls are created equal. That's hard to beat IMO. philhas Members 61 459 Location: North East England There is one aspect in which a Kellner can actually outperform a Plossl: eye relief. 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. Good quality. Astrophotography with Nikon D3200: Can It Be Better? Plossl eyepieces are perfect for astronomical viewing because the field of view is wider. These are things you will want to know and use. However, I have eyepieces that have larger exit pupils than 7 mm and they work well. Then set your maximum based on your aperture and split it up. They are a good brand with high-quality eyepieces, you just dont need to spend the extra money for almost no gain in performance. Thanks all. There was an old Meade Super-Plossl design that used an additional lens element and could reach a wider field of view.
Many brands of eyepieces are available, including SVBony UltraWide, Astromania UltraWide Angle, Agena Astro StarGuider Enhanced UltraWide Angle and others. Fully coated optics provide crisp and bright views of the cosmos. If you want to buy him $200 eyepieces so he can grow into them, that works. Offering a wide 52 apparent field of view, these 10mm, 17mm, and 25mm Orion Sirius Plossl Telescope Eyepieces provide extremely sharp images of impressively high contrast. In the box you'll receive 5 1.25 eyepieces at following sizes, a 32 mm Plossl Eyepiece, 17 mm Plossl Eyepiece , 13 mm Plossl Eyepiece, 8 mm Plossl Eyepiece, 6 mm Plossl Eyepiece, a 2X Barlow Lens 1.25. A long eye relief is also important for those who wear eyeglasses at the eyepiece, whether thats a member of the general public at a star party or an astronomer with astigmatism, which, unlike near- or far-sightedness, cannot be corrected with the telescopes own focuser. Through the 32mm eyepiece, objects will look larger, and though they may have a lower surface brightness, the surface brightness of the background sky will also be lower. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Stargazing Help came into existence when some young minds got mesmerized by outer space while camping. Lower power almost always looks better than higher power. We will use a 100 mm telescope with a 600 mm focal length that only takes 1.25 eyepieces. The original design for Plossl eyepieces has existed since 1860. We may earn commissions by recommending products on this website. I beleive this is the same as they ones you asked about. What should one opt for a 2 EP over a 1.25? The bottom line is that it is best to have several magnification choices so you can optimize the view. That can only be shown through actual testing. And I am a visually observing focused person. So we say that an F5 scope benefits from better corrected eyepieces more than the F10 scope. 2. They are not that expensive I would pay about $100 for both eye pieces. Plossl eyepieces have an eye relief equal to about 80% of their focal length. If you are just testing the waters or on a tight budget, get the Celestron, which is still pretty good. Sometimes you want to see a wider field of view to locate an astronomical object like a nebula by using nearby stars. Save my name, email, and website in this browser for the next time I comment. These will normally be higher priced and may be outside the price range we show here. 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.
