Just give yourself some time to learn the app and to understand the scope. 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. The biggest advantage is much better ER in a large ocular. Perhaps you should seek out help from your local astronomy club. 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 are upgrading, avoid ones that say correct image as these add a prism system into the diagonal which can reduce the light transmission. It also produces an erect image, meaning you see what youre viewing rather than seeing everything upside down or sideways as some types do. ES 82 degree series plus 1 meade uwa @20 mm with 1800 focal length optical tube lowest mag 51 x / highest mag 300. Is it just about finding and framing, or do wide fov EPs create a more immersive experience? Because of this setup, you might also hear a Plossl eyepiece referred to as a symmetrical eyepiece. I had a newer - purchased in 2016 Meade 32mm (white lettering) that was no better than the older 32mm 4000. But for AP you should really start your planning with the mount. It was named after Peter Barlow who invented it in the 1800s, so it is usually capitalized. 4. Imagine you are looking at the moon with each of these eyepieces and consider what you would see. 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. did i pass? Comparing to Plossl eyepieces, Super Plossl is somewhat better for astronomy. Simple Plosels work well and unless you have money burning a hole in your pocket, I would start with simple affordable eyepieces. But, at least get the 32mm Plssl. Tip Its almost always cheaper to buy directly from Agena Astro. The quality of a Plossl eyepiece completely depends on the brand and model, so be very careful in our selection. 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. I consider the Plossl to be the minimum standard for a good eyepiece. Or we say that F10 would be easier or less demanding on the eyepiece than the F5. While I also have the Baader Hyperion Zoom, mentioned later, I continue to make use of the Celestron, especially in my smaller scopes. 1.25" Power mates with T ring adapter. Do you need to have the best to enjoy astronomy? The Japan made 16mm Meade 3000 was a very nice medium power plossl and the 40mm in that series was surprisingly nice as well. 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.) Perhaps another review would be helpful. Etc.? At one time Plssls were premium eyepieces. Are Plossl eyepieces any good? A 20mm Plssl is probably worth it, if for no other reason than to compare the views it gives to the 21mm Hyperion you have. OK that makes sense, many thanks. Plossl eyepieces are perfect for astronomical viewing because the field of view is wider. 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? Most people prefer the wider TFOV. These eyepieces have about 35 to 50 degrees apparent fields of view and reasonable eye relief, though quite short for high magnifications. Thanks in advance I really appreciate it! Plossl against Kellner eyepieces in a previous article, 5 Budget Telescopes That Are Sneakily Powerful. Differences and Similarities. The eye relief is the distance between your eyes and the eyepiece where you are able to view the whole image comfortably. Here are a few types of eyepieces you may read about and their typical AFOV. Kellner eyepieces, on the other hand, are generally pretty close to each other in terms of quality so theres little chance you will get much variance in image definition between brands. 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. But will the Baader CO with 1.5-2-3x Barlows deliver a visibly sharper and more contrast view of the Moon and planets than the zoom lens with a 2x Barlow, to compensate for the zooms convenience that is the question! Oh the pain of uh having access to really cool eyepieces.). Finally, the worldwide pandemic has led to shortages and price jumps on many items. So you would have to test the set to see the actual result. One of the TMB Planetary eyepieces are extremely nice for 50. A zoom eyepiece works like the zoom lens on a camera. 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. In High School, they told me that F=MA In college I learned that F=dp/dt But F=MA works well enough for most situations and that is how I think of it. I agree. Fully coated optics provide crisp and bright views of the cosmos. That is a really interesting picture. I expect such eyepieces are available but I have never seen or used one. They have a pop-up eye guard and they are threaded to accept filters. It doesnt matter what type of telescope you have, as long as your scope takes these standard sizes.

With an f/10 telescope, Plossls are as sharp as any other kind of eyepiece of the same focal length. Eye Relief: This refers to how close your eye has to be to the lens in order to see the full field of view. My Baader Hyperion Zoom is my most used and favorite eyepiece. . 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. It comes with two Barlow lenses, one Newtonian eyepiece, and three Plossl eyepieces in the set. thanks for all your help. Take a look at your manual or users guide. At that price point, it couldnt compete with other 5-element devices like Erfle and Nagler eyepieces that had better performance. Divide that by the magnification of that eyepiece in that scope. They are not that expensive I would pay about $100 for both eye pieces. You noted eye relief is important for those wearing glasses. A 32mm plossl eyepiece and a 2x barlow lens should be enough to give you a good range of eyepieces for every use case. 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. By the 1980s, amateur astronomy equipment suppliers were still selling new telescopes with Huygens and Ramsden eyepieces, not merely because they were cheap but because they lacked internal reflections. They have decent eye relief and little curvature of field. Glad you found it helpful. I do not miss beating my eyelashes against a 9.7mm Meade Plossl that I used to own. Plossl eyepieces have an eye relief equal to about 80% of their focal length. I have personally tested a few Super Plossl and compared them to their regular counterparts by the same brand. These are matters of individual preference and budget. 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. Lenses are fully multi-coated for excellent light transmission and reduced internal reflections. Even if you did need a 4mm focal length (for high powers in an f/4 telescope, of course), neither a Kellner nor a Plossl would have long enough eye relief for that to be comfortably usable! At 32mm, a Plssl will give you as wide a field of view as any 1.25mm eyepiece can. In the beginning, you are not going to know what the atmospheric conditions might be in your area. Plossl eyepieces have an eye relief equal to about 80% of their focal length. Since each eye has a different focal point, I suspect pulling the eyepiece out until reaching focus and then tightening the set screw. . I also really liked my E-Lux 32mm, a Kellner. 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. However, I have eyepieces with much smaller exit pupils and they work fine. I owned an XT8 Intelliscope which is the same optical tube on a PushTo mount. One last thing, as a kid I used my telescope to watch squirrels and birds (which was interesting because the image was flipped around :-) so, you might consider getting an eyepiece that flips things the right way around so that navigating terrestrial nature is easier to manage. Some optics brands have taken the next step and launched some eyepieces they have labeled as Super Plossl. If you are very demanding and must have the very best, this is where you want to be. I have seen some gatekeeping in this hobby about Kellners, and Im not sure I understand it. We also joined our local Astronomy Club and look forward to joining others under the night sky when the opportunity presents itself again. To achieve these benefits, they may use special glass and more costly manufacturing. How do you focus - I would have expected helical focusers in the eyepiece holders but don't see any? You can buy a range of these from Modern Astronomy. We can see that 2 eyepieces have an advantage over 1.25 eyepieces when designers are making wide-view eyepieces. Sorry but I am not offering a configuration and pricing service. Using this 40 mm Plossl eyepiece is an excellent way to get a wide field of view with your telescope. Just search on Astronomy Club and you will probably find one in your area. The difference in TFOV will be significant at this focal length. This is not a hard and fast rule, just a cautionary note. It will also make your life easier if youre out observing on windy days that would otherwise blow off the front cover of your telescope. A decent barlow might cost as much or even more. So perhaps you do your line up like this. So, I am going to organize the guide around five questions and four formulas. 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. You are talking about the technical details of how a Barlow works, and I agree. Im also uncertain about what to expect from an additional investment? You mentioned regarding ORTHO eyepieces: Excellent specialty eyepieces, usually for planets. Understanding and using a Barlow Lens However, some eyepieces have an eye relief as short as 5 mm. You can email me also. This is my all-time favorite eyepiece and the one I use more than all the others put together. These eyepieces are technically called Symmetrics, since Plossls can have different focal lengths for each doublet, but they are always marketed as Plossl. My Barlow is a 2X with a removeable Barlow element that can be screwed right onto an eyepiece giving a 1.5X effect. Gosky Plossl 40 mm Telescope Eyepiece - 1.25inch This is probably the worst eyepiece I can recommend. Then set your maximum based on your aperture and split it up.

Under my sky it was rare that I would be able to get over 225X and still maintain a good quality image, except on the Moon. Higher values are slower and lower values are fasterthis is a holdover from camera lens terminology and has to do with exposure times.). They also improve a bit when it comes to eye relief. Thanks, Angelo M. You picked a great first scope. We will use 10 mm as the eyepiece focal length, but we will look at three different 10 mm eyepieces, each with a different apparent field of view, AFOV. I think you will love it! 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. Eyepieces under $100 each are generally considered budget or low-cost eyepieces. There is a little bit more to it than that and there are other design .

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. Those are significantly more expensive than the 1.25 focal lengths. For that purpose it is probably easier to find one to borrow. 75-225X, 1.5X Barlow I still use my 30mm Celestron Ultima fairly often with some of my telescopes. In the next section, we will talk about the AFOV of an eyepiece. There are inexpensive adapters that will let you use standard 1.25 eyepieces in a .965 focuser/diagonal. (Svbonys Plossls, for example, are optically identical to Orions Sirius Plossls). This is your Lexus, Acura, and Infinity types that offer more features, better build, and a bit more polish. But what are the differences between these two and how do you know which one to choose?

I hope I can say that someday. Also, as the apparent field of view gets wider, the image will require more correction. 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.

These will normally be higher priced and may be outside the price range we show here. We have a range of 32 mm to 3 mm. It has made learning the Constellations and star-hopping more fun and engaging for my whole family exactly what I was hoping for. I often recommend a 32 mm Plossl as a good low power wide view eyepiece for scopes with a 1.25 focuser. Eyepieces are a religion. If that surface is wobbly the scope will be almost useless. For what it's worth: I believe the Omni 1.25 inch 2x Barlow is one of the Shorty Barlows manufactured by GSO. The BHZ 2 Adapter has threads on it so you can attach filters to it allowing you to use 2 filters with the zoom. Combining a cheap eyepiece with a cheap barlow isn't a elegant solution. Eye relief of less than 10mm gets really uncomfortableyou tend to rub your eyepieces against the eyepiece or lens, and you have to hold your eye at just the right distance to keep from touching the lens. Age is not part of the equation. You probably dont need to worry about upgrading them as soon as you get your telescope, unless you can see an optical problem in the one youre using or you find the short eye relief for the short-focus eyepiece uncomfortable. The sharp/crisp view you get from your 40mm Plossl comes down to the relatively low magnification it provides. 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). You might be able to find a Kellner, or perhaps a high-quality Orthoscopic. Besides fov, How would you compare the optical quality of the Celestron to the Baader? The Orthoscopic Plossl eyepiece is for those who are interested in performing close-up work on specimens up to three inches away from them and still get high magnification. Read our full affiliate disclosure here. With modern multi-coated optics that thwart internal reflections, Plossls and Kellners have little difference in glare or transmission/opacity. In this article, were going to talk about what is a Plossl eyepiece, what are its components, how do they work, how many types are there and how youd buy a good Plossl eyepiece.

Because some objects look better at low power, some at medium power, some at high power, and some at very high power. But the longer FL units are certainly useful. The Hyperions work well in SCTs and you can't beat that large eyelens and eye relief ,JMO. This is perfect for a 25mm Plossl (an extremely common standard) and downright luxurious with a 32mm Plossl, but when you get below about 12.5mm or 10mm, it can begin to get difficult to use. The magnification and field of view is the same as a 10 mm eyepiece (AFoV being unchanged) in a 600 mm telescope but the eye relief is that of a 30 mm eyepiece.

The Regular Plossl eyepiece is made to be a basic type of scope for viewing objects that are nearbysay within two feet or so from where youre looking through it. As to a more immersive experience, yes, I would say a wider FOV does provide a more immersive experience. They can also be found as Orion Expanse sporting a blue line rather than gold. Thank you so much for taking the time to provide all this information! FOR SALE! I beleive this is the same as they ones you asked about. Stargazinghelp.com is a knowledge hub for professional and amateur astronomy and astrophotography enthusiasts. It may be a bit less than that in reality but for practical purposes that is close enough. They are most useful in medium and longer focal lengths for terrestrial, planetary, and lunar viewing. 70 mm scope will have a max of 140X for planning purposes. You can do that by using this long focal length eyepiece. They have a narrow AFOV but have a reputation for being very sharp.. Another way to look at it is that a 30 mm eyepiece in a 3X Barlow works like a 10 mm eyepiece. Now put the zoom on a 3X barlow and you have: Using the zoom approach with a Barlow your eyepiece set would consisit of a 32 mm low power eyepiece. I am not aware of any such solutions for Newtonian reflectors. Remember that visual and AP have very different requirements, so plan on at least two different optical tubes.
