I cant answer that specifically as I have no experience with that eyepiece in that scope. Thanks for a very helpful guide. 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. Its quite long but that is what we are aiming for and hopefully, it was useful to you. In simple terms, high focal ratio scopes, say those over F6, tend to be less demanding on eyepieces than those below F6. Again, does it create a more immersive viewing experience? Be aware of the focal ratio of your scope. 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. Now we just divide it up and fill in some sample focal lengths. At 32mm, a Plssl will give you as wide a field of view as any 1.25mm eyepiece can. It doesnt matter what type of telescope you have, as long as your scope takes these standard sizes. These are just a few examples of eyepieces that I have used, and some that I own. 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 really understood the material. Their 50 to 52 degree AFOV is wide enough for general observing. Regular Plossl eyepieces with maybe just a slightly better coating or build quality. But just because an eyepiece is 2 doesnt mean it has a wider field of view than one that is 1.25. Something in the 30 to 38 mm range with a 65 to 70 degree AFOV. 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 I think you will feel more confident about your purchases and be less likely to be disappointed if you read through the guide. Another useful aspect of a wider field of view is that, assuming the entire eyepiece is sharp enough to show good images right to the edge, you dont have to nudge the telescope to track the rotation of the Earth as often with a Plossl (50 degrees) compared to a Kellner (40 degrees). Typically a Barlow does not add or subtract from this, but there again we have bad Barlows and Good Barlows. did i pass? Many brands of eyepieces are available, including SVBony UltraWide, Astromania UltraWide Angle, Agena Astro StarGuider Enhanced UltraWide Angle and others. If you upgrade the telescope or add a second one, the eyepieces will work on that telescope too. The generic GSO Plssl from many manufacturers, including Astronomics (Astro Tech) and Agnena Astro, is as good as the Celestron and a few bucks cheaper. 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.

Sometimes you want to see a wider field of view to locate an astronomical object like a nebula by using nearby stars. 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. The field of view of the eyepiece has a few effects when it comes to actually using it in the telescope.

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. These companies rebranded them under their own names. I really like the simplicity and compactness of these simpler designs (ie: Plssls, Orthos, Kellners, etc). Know what diameter eyepieces your scope takes. The Plossl optical design is very good for long and medium focal length eyepieces, delivering a sharp, flat field and an apochromatic image. As long as you take good care of them, Plossls can last you a lifetime, and you will be able to use them with your next telescope if you upgrade at some point. When you are shopping, if you need long eye relief, make sure you are selecting the correct ones.

The "sharpness" you are seeing may well be better explained by the focal length of the ep than the quality of Plossls in general. 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. 100-300X, 2X Barlow. Looking forward to first use. 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. And certainly, if you are getting into AP you are going to need that big budget. This may be enough for many eyeglass wearers. These eyepieces have about 35 to 50 degrees apparent fields of view and reasonable eye relief, though quite short for high magnifications. I also struggled to see features on both (gas bands on Jupiter and clear rings on saturn).

The more light that is gathered, the more magnification that can be applied to the image, up to the limits that are imposed by the atmosphere. Low focal ratio scopes deliver the light rays to the eyepiece at an ever-increasing angle as the focal ratio number goes down. One learns by observing. You could base this on 3, 4, 5, 6 or more focal lengths/magnifications. Get to know more about us here. A large field lens makes the ocular easy to look into. In addition, the eyepiece would be a Huygens or Ramsden design, where two lenses made of the same type of glass could be combined to yield minimal false color fringing, as long as the focal length of the telescope remained fairly long.
