To estimate the highest practical magnification for your telescope, you take the aperture in millimeters, mm, and multiply it by two. Celestron Omni Eyepieces: The Omni series is the most economical eyepiece offering from Celestron. This might contain more of what you need. (Compare, for instance, 20mm of each type, or 10mm of each type.) I really enjoy usingPlssls. > Click here to jump to the Best Eyepieces section. From planetary viewing to deep sky watching. Yes, Plossl eyepieces are some of the most popular with amateurs and professionals alike. I usually recommend a 32 mm Plossl type eyepiece as that provides about the widest view you can achieve with a 1.25 focuser. If well made, Plossls are bright, with good contrast, and a flat field, and excellent sharpness. Now, for my one or two low power eyepieces, I also like to know the field of view provided by that eyepiece. I have Celestron and the Baader Hyperion. The stock 9 and 15mm Omnis were very good. The price ranges we show here are the typical prices. Plossl against Kellner eyepieces in a previous article, 5 Budget Telescopes That Are Sneakily Powerful. Generally, dont mess around with solar projection unless youre okay with damaging the instrument. There are so many others at comparable or higher prices, many of which are quite good and some rather poor. Kellner vs Plossl - Comparison table. The Plossl eyepiece is a type of optical system that was invented by Ernst Abbe. You have to decide how fussy you are about the edges and what your budget can tolerate. A Kellner eyepiece has 1 double lens and 1 single lens. People may have heard, and rightly so, that Huygens or Ramsdens are crummy eyepieces and that they should get a Plossl instead, and they may believe the same applies to Kellners, but the truth is that Kellners are often good eyepieces. condition as described, a good transaction. . The components of a Plossl eyepiece are the two groups of lenses. Thanks in advance I really appreciate it! No price limit? Again, does it create a more immersive viewing experience? 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.

I decided to jump in with both feet and get an Orion ED80 (600mm f7.5 with a 2 focuser, So that I can move into astrophotography down the road. If you go this route, you can always add single focal length eyepieces along the way to serve specialized purposes. This eye piece provides the maximum true field of view in the 1.25 inch format. A Plssl is probably as good as any 32mm eyepiece in a 1.25 inch focuser. Kellner eyepieces use three glass elements in two groups to minimize color fringing. These are often compared to the higher priced offerings. Because the eyepiece was still similar enough to a Plossl and still kept the symmetrical design, they called it Super Plossl. Plossl vs Super Plossl Eyepieces: The Differences - Stargazing Help I started with the Celestron zoom. Today, most beginner telescopes of any quality are sold with either Kellner or Plossl eyepieces. Kellners tend to have narrower apparent fields of view (40 degrees rather than 50 or 52 degrees in a Plossl), and in short focal length telescopes (focal ratio f/5 or shorter) they can have more false color fringing, but for the most part it is hard to notice the difference between a well-made Kellner and a well-made Plossl in terms of image quality. Disclosure - If you buy something via our link, we may earn a commission with no additional expense to you. (Svbonys Plossls, for example, are optically identical to Orions Sirius Plossls).

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. Both will provide the same magnification. In comparison, Aspherical lenses generally have no color distortion but might not work out well if the telescope user needs really high magnification. Most modern telescopes use a focuser, or diagonal, that accepts 1.25 eyepieces. Very worth it for me, as I like to use bino-viewers. A decent barlow might cost as much or even more. Meade 32mm 2" 5-element Super Plossl Wide Field Eyepiece Gosky 1.25inch Plossl Telescope Eyepiece - Amazon.com I often recommend a 32 mm Plossl as a good low power wide view eyepiece for scopes with a 1.25 focuser. A very good quality eyepiece for a reasonable sum. If your scope uses eyepieces that are closer to 1, then you have an old style .965 that is now obsolete. These are two very important considerations when you are looking for eyepieces. You are asking about a very specific eyepiece in a very specific scope combined sometimes with a Barlow. 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. Good value. It should list what size eyepieces you can use. This doublet design has an apparent field of view of 50-degrees or wider but can suffer from short eye relief making them difficult to use for some . Then set your maximum based on your aperture and split it up. Many Kellners are made with field stops opened up to 50 degrees, in which case it can truly compare to a Plossl in any telescope with a focal ratio of f/6 or slower. Gosky Plossl 40 mm Telescope Eyepiece - 1.25inch This is probably the worst eyepiece I can recommend. Overall, I would highly recommend the goldline eyepieces. Suggesting an F6 scope becomes an F18 would also imply things like reduced CA in a refractor. If there is a local club, I would suggest you visit and consider joining. What is a Plssl eyepiece? | BBC Sky at Night Magazine For super Plossl eyepiece, the field of view is typically 40 to 60 degrees. I like my 38/70.

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. 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. Recall that your lowestpower eyepiece's exit pupil should not exceed 6mm. 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. The basic design hasnt changed much, but the real costs of manufacturing have dropped. thanks for all your help. Plossl vs Kellner Eyepieces: The Ultimate Comparison 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.

The Plossl eyepiece has 4 lenses, consisting of 2 identical double lenses. The telescope comes with a 2x Barlow so I was thinking of getting one of the zooms you recommended. And new proprietary designs come out from time to time. No other type can compare with it when it comes to that quality. EP-mm = magnification = afov 11 = 163 = .5 But dont fear that you will waste your investment as eyepieces are standard sizes. Low focal ratio scopes deliver the light rays to the eyepiece at an ever-increasing angle as the focal ratio number goes down. My own lineup (with a C8) is 32mm Plossl, 18.2mm DeLite, and 10.5mm Pentax (the last one not chosen to match, but rather because it belonged to a deceased friend). I had a bino pair of TV 20mm Plossls, very fine for high power planetary observation with my long focus 8" Mak, then I also bought the older TV 21mm Plossl, after trying the 21mm I sold the more recent 20mm. With a refractor, SCT or MCT, it is usually better to get a correct image diagonal than a correcting eyepiece. Also work very well with my binoculars that have removable focal reducers built into. 6.5-ish mm (100x & 200x) You are talking about the technical details of how a Barlow works, and I agree. This design features 4 lenses that are paired in two close-set doublets for the eye lens and the field lens. If your focuser/diagonal only accepts 1.25 eyepieces, I would recommend you use a 32mm as your longest focal length, lowest power eyepiece. If that is the case, it will give me another reasonably good, inexpensive zoom to recommend to beginners. With modern multi-coated optics that thwart internal reflections, Plossls and Kellners have little difference in glare or transmission/opacity. So yeah, they are good.. and some are even better than others, and more collectible.

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. I want these as possible as wide, magnification and astrophotography purpose. 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. There are inexpensive adapters that will let you use standard 1.25 eyepieces in a .965 focuser/diagonal. Plssl's were top of the line at one time, and are still being sold today, so that says something too.

This means less time trying to figure out which way your images should be oriented before examining them. 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. If you had to choose 1 low-power 2 EP for chasing deep sky objects (again, at 600mm f7.5), what size piece would you go for? No results, please adjust your filters. What should one opt for a 2 EP over a 1.25? I also just bought the Celestron Starsense 102mm refractor (650mm focal length, f/6.5) as a first scope for me and my kids.
