I wont go into all the types of aberrations that can be there. Most of Celestrons entry-level telescopes are sold with Kellners (and other cheap but reasonable-quality designs like RKEs or Konigs), whereas their more expensive SCTs tend to come with a single 25mm Plossl. no caps come in bolt case. Most people will be fairly comfortable with eye relief of 12 mm or higher. But in this scope, the 32 mm doesnt work well. In essence the design differences between Kellner and Plossl comes down to the number of lenses within the eyepiece barrel. A Plossl eyepiece has a field of view thats very wide, so if youre looking at the full moon or some other object in space with it, chances are youll see the entire thing. You are asking about a very specific eyepiece in a very specific scope combined sometimes with a Barlow. Many brands of eyepieces are available, including SVBony UltraWide, Astromania UltraWide Angle, Agena Astro StarGuider Enhanced UltraWide Angle and others.

I started with the Celestron zoom. 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. 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. . However, you may see them at higher prices for the short term. Where a difference can show up is that a lower number focal ratio scope will make it harder for an eyepiece to provide a uniformly good, in-focus image all the way across the field of view due to the steeper angle that the light arrives at the edges of the eyepiece with a low focal ratio scope, as compared to a high focal ratio scope. Looking from different sorts I found the Baader Aspheric 31mm and 36mm.these two eyepieces allow me to switch between 2" and 1.25"just by changing the barrel.

Look at the apparent field of view specs and understand what this means for the field of view. Celestron Omni Eyepieces: The Omni series is the most economical eyepiece offering from Celestron. One learns by observing. Note that as we get into the higher magnifications, the millimeter jumps between eyepiece focal lengths gets smaller.

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. For me personally, even though I don't use glasses to observe, I still don't want to dig out the view through a plossl or ortho eyepiece which tend to have short eye relief.

Combining a cheap eyepiece with a cheap barlow isn't a elegant solution. That is a really interesting picture. Those that still come with Huygens and Ramsdens are generally cheap and low quality, since practically the only reason to use those designs in modern times is that they are extremely cheap to manufacture. 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.). Its made up of four lenses in two groups. To say it a different way, in general, an F5 scope will place more demands on the eyepiece around the edge of the field of view than an F10 scope. I possess an embarrassing array of fine eyepieces with names like Ethos and Nagler and Delos. 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. But just because an eyepiece is 2 doesnt mean it has a wider field of view than one that is 1.25. Does this sound like something you would recommend based on the telescope I have? 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.

So if you need to go to Arcturus and then go 2 degrees to the right to find your target, you can use the FOV of the eyepiece to estimate 2 degrees. 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. Glad you found it helpful. 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. Major telescope brands such as Celestron supplies Kellner eyepieces with their r least expensive telescopes and still may. Better edge correction with a short-focus telescope is one of the things you pay extra money for, and sophisticated eyepiece designs have as many as eight elements.

The TFOV of the Hyperion will be greater than the TFOV of the Plssl, but the magnification will be about the same. 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. 32 mm = 18.75X12 mm = 50X8 mm = 75X6 mm = 100X4 mm = 150X3 mm = 200X. The Plossl was also called a Kellner Type III in some earlier references; in the 1950's, Edmund Scientific sold a "Kellner" eyepiece made from war surplus lenses, but it actually consisted of two achromats in the classic Plossl configuration. The downside to this type of lens is that they can cause chromatic aberration which creates colored spots around bright objects such as planets or stars due to the different wavelengths not going through equally. We will talk more about the field of view later, but note that if you can use 2 eyepieces, you will typically only have one or two for very low power wide field views. Their 50 to 52 degree AFOV is wide enough for general observing. We have a range of 32 mm to 3 mm. Typically, these will be 25 mm and 10 mm or something close to that. The one exception I would keep in mind would be when working with Newtonian reflector telescopes below F5. At that price point, it couldnt compete with other 5-element devices like Erfle and Nagler eyepieces that had better performance. It may very well last you a lifetime and in the long term, you will definitely consider it to be a worthwhile investment. Any 1.25 diagonal should work.

You can use the same eyepiece on planets and deep-sky objects (DSOs). This is a good thing, because normally the shorter the focal length of the eyepiece, the less eye relief you have.

Thinking in a super ploss 32mm and maybe something between 9mm and 15mm . It was named after Peter Barlow who invented it in the 1800s, so it is usually capitalized. She has been looking at the sky for years and hopes to introduce more people to the wonderful hobby that is astronomy. The atmosphere is typically the limiting factor as we get to higher magnifications. . By having a range of magnifications, you can optimize the image, which means you need more eyepieces. I have since moved up to a 12 Dob but I use the same eyepieces and the BH Zoom continues to be my most used. It sounds cool, they must be better than regular Plossls with that name, right? 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.
