Besides fov, How would you compare the optical quality of the Celestron to the Baader? I dont think so. Note that as we get into the higher magnifications, the millimeter jumps between eyepiece focal lengths gets smaller. Offered in both 2 and 1.25, these are excellent eyepieces. This 10 mm Orion Sirius Plossl Eyepiece is a great, moderately high power ocular for observing small planetary nebulas and globular star clusters, as well as for planetary probing when seeing conditions don't permit higher magnifications. With regards to budget, whatever works well and is on par with the quality & capability of the telescope. It costs three to four times as much as the Celestron Zoom, but if you have the budget, this is the one to get. Worth is a subjective evaluation, so here is my subjective input: 1. 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. Good evening everybody. The Baader offers wider fov, but at quite the price premium. These are matters of individual preference and budget. The 26 and 32 are usually the first ones I reach for. Lower power almost always looks better than higher power. They also offer a generous 16 mm of eye relief which is most important in the shorter focal lengths. Below .5 mm exit pupil, floaters in the eye become more apparent and can be bothersome. So its best for use during duller times when there isnt much brightness visible. Good 32mm Plssls run around $30-$40. An exit pupil larger than 6 mm may start to show a shadow of the secondary mirror. This design features 4 lenses that are paired in two close-set doublets for the eye lens and the field lens. Well-made lenses are expensive though, so in general the more lenses, the higher the price of the eyepiece. And I continue to read excellent reports on the AT Paradigm and similar under different labels. This design has some advantages over other designs, such as the Kellner eyepiece or Orthoscopic eyepieces. Plossl eyepieces have wider fields of view than Kellners. 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. This also makes them more resistant to any form of dust getting inside the eyepiece.

Not only is it good to share the experience but you can get first-hand advice on things like diagonals and may even be able to try one in your scope to see if it makes a difference. They are also good for those who have astigmatism because they are designed to be more forgiving with eye placement. It offers good color correction and high-contrast images. We also joined our local Astronomy Club and look forward to joining others under the night sky when the opportunity presents itself again. thanks Ed. You really understood the material. This wider field of view will make it easier to find your targets, allow you to view larger deep-sky objects, and provide a more immersive experience for everything that you view. What Does It Do. Again, for no other reason than to compare it to the 17mm Hyperion and draw your own conclusions about Plssls. Rating (max 5): Here we focus on becoming a knowledge hub for astronomy and astrophotography enthusiasts. Some optics brands have taken the next step and launched some eyepieces they have labeled as Super Plossl. So yeah, they are good.. and some are even better than others, and more collectible. I think I will go for the BHZ because, as you say, I will be able to use it now and into the future. Many thanks, Sophie. These eyepieces have about 35 to 50 degrees apparent fields of view and reasonable eye relief, though quite short for high magnifications. philhas Members 61 459 Location: North East England THANK YOU x 12! When you add eyepieces to your collection, you will want to consider what field of view you want and how much you are willing to pay for it. 600 mm / 200X = 3 mm This will be the focal length of our highest power eyepiece. And I am a visually observing focused person. How does that field of view impact the viewing experience? The views through it are very impressive, and it always amazes me when I get that one out. i did buy an astro-tech 3.2 paradigm ed from a cloudynights.com forum member. Am I correct? I think you will change your mind. Theres a reason Plossls are usually kept at 52 degrees. You can buy eyepieces specifically focused on a particular scope or you can buy eyepieces that you expect to use with this and all future scopes. I just ordered Hyperion 13mm and 21mm but I really like how sharp and crisp view is in plossl 40mm. In the world of eyepieces, when you want the very best, turn to Tele Vue, but be prepared to pay a truly premium price. They have a narrow AFOV but have a reputation for being very sharp.. And the zoom provides every magnification in that range without having to change eyepieces. Most telescopes come with one or two eyepieces. Gold Line eyepieces also offer better eye relief than Plossl eyepieces, especially at the shorter focal lengths. 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. To achieve a maximum of 200X (2X the aperture of 100 mm), we solve for the focal length. Orion SkyQuest XT8 Intelliscope Review Scott. Imagine you are looking at the moon with each of these eyepieces and consider what you would see. They are also really sharp. What I can say is that, in general, eyepiece characteristics are inherent to the eyepiece. Brilliant article and I thank you for it, I was literally really confused prior to reading it.

Again, does it create a more immersive viewing experience? While many people will stay with and add Plossls to their eyepiece set, I would recommend not going below 10 mm focal length as the eye relief gets quite short. 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. 3. Best Telescopes For 10 Year Old Kids: Reviews and Buying Guide, The Complete Guide to the Planets You Can See With a Telescope, The Best Barlow Lenses: Reviews and Buying Guide. You have selected a very good starting telescope that will serve you for many years to come. What Is A Barlow Lens For A Telescope? Lets look at the minimum. 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 case of the Celestron, you get all the focal lengths from 24 to 8mm in one eyepiece that costs $100. 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. Over $250, I will label premium eyepieces. Super Plossls offer a smaller field of view, which makes them good for close-up views and examining small objects. I have to say that your questions are answered in the article. 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. These eyepieces are technically called Symmetrics, since Plossls can have different focal lengths for each doublet, but they are always marketed as Plossl. They can also be found as Orion Expanse sporting a blue line rather than gold. 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. These are considered to be the least expensive eyepieces for serious astronomy and are offered in focal lengths from about 6mm to 40mm. 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. I had a newer - purchased in 2016 Meade 32mm (white lettering) that was no better than the older 32mm 4000. 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. That is a wonderful expression. These are often compared to the higher priced offerings. If you cant use 2, that 32 mm Plossl, which has a 50 degree AFOV, will give you about as wide a field of view as you can get in a 1.25 eyepiece. Yes, Plossl eyepieces are some of the most popular with amateurs and professionals alike. You will get varying opinions on this but I would not worry too much about this. They are just OK, but I dont recommend them, especially in a low focal ratio scope. Some of these series also offer 2 eyepieces for telescopes that can accept 2 eyepieces. I consider the Plossl to be the minimum standard for a good eyepiece. 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. Do you need to have the best to enjoy astronomy? We have compared Plossl against Kellner eyepieces in a previous article. I tested out my BH zoom yesterday for the first time and it is a great eyepiece so thank you for the recommendation! Below 20 however, the eye relief makes it difficult for me and my glasses so Ive been replacing my 5-15 EPs with 82 degree EPs with more relief.

I have owned wider eyepieces, but ultimately I just prefer the Plssls (must be a mental defect). 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. A 6mm Plossl has a tiny eye lens. What focal length eyepieces should I buy? These are exceptional eyepieces, and only available on the used market nowadays. Plossl eyepieces are perfect for astronomical viewing because the field of view is wider. 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. 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. short answer: yes. Their 50 to 52 degree AFOV is wide enough for general observing. Aspheric and Plossl Plossl are both lens designs that can be used in most telescopes. Meanwhile, Plossl eyepieces are much more common and easy to find. A 15mm Plssl might be worth it, if you dont wear glasses.

Another really helpful article, Ed. In this case, I am going to define this by the focuser and eyepiece size. 100-300X, 2X Barlow. With a refractor, SCT or MCT, it is usually better to get a correct image diagonal than a correcting eyepiece. I continue to be very pleased with the ES82 eyepieces. As we go up in price range, we gain capabilities that may not be immediately obvious. The third choice of eyepieces is the Orion 12 mm Sirius Super Wide Angle Correct Image Eyepiece. We are a reader-supported organization. If you are new around here and you want to get started with the hobby, check out our astronomy for beginners guide or the recommended gear page. Now we just divide it up and fill in some sample focal lengths. Also, atmospheric conditions can limit how much magnification you can use on a given night. One of the main drawbacks of this eyepiece, though, is the eye relief. But I have one little niggle. I saw Jupiter today and its 4 moons but when I looked at saturn I struggled to get a really clear image and it was very small. 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!
