These sport a 60-degree apparent field of view, about a 20% wider apparent field of view than Plossl eyepieces. 1200 mm FL scope / 10 mm FL eyepiece = 120X, 40 degree AFOV / 120X = .33 degrees (less than 1 full moon wide), 60 degree AFOV / 120X = .5 degree FOV (about one full moon with no space around it), 82 degree AFOV / 120X = .68 degree FOV (about one full moon with a star field around it to frame it). In the 1990s Meade instruments came up with a new design for the Meade 4000 line similar to Plossl that added a fifth glass element on top of the two pairs (4 total). 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. Other eyepieces of more advanced design can have better eye relief and field of view. Newer multi-coatings are better, I suppose, but newer does not always mean better in the ocular game. Plossl eyepieces are great. It was grueling, because I couldnt even get the entire field of viewI had to keep my eye hovering above the exit pupil.

Stargazing Help is a participant in Amazon Associates program. At shorter focal lengths they have less eye relief, and at all focal lengths they have a narrower field of view, than newer types. Plossl and Kellner eyepieces are two very common examples of a simple eyepiece design, and they are probably the most common type of eyepiece you are likely to come across when eyepieces have been bundled with a telescope; they are also a very common aftermarket accessory.

They also offer more eye relief than Plossls at the shorter focal lengths. For astronomical observations, such as viewing craters on the moons surface from Earth, high-magnification models are preferred because they offer more detail. It also gives the widest possible exit pupil in my dob and SCT, very handy when using nebula filters.

Im just starting out with astronomy and this really helped my understanding. The BHZ in a 2X Barlow will take an XT8 to 300X. 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. But, if you have a plan, you can fill in those slots, working toward a well-balanced set of magnifications. But you need to know, first, if you will be wearing glasses when you observe.

Fully coated with magnesium fluoride on every air-to-glass surface for excellent light transmission and high contrast views. They provide a range of magnifications with one eyepiece. A 32mm plossl eyepiece and a 2x barlow lens should be enough to give you a good range of eyepieces for every use case. If your focuser/diagonal will accept 2 eyepieces, then I will suggest you get one or two 2 eyepieces for your low power wide view eyepieces. Yes, eyepieces is a large and complex topic. Understanding and using a Barlow Lens I already got the 10mm super wide because of the added eye relief but at 15mm both have the same eye relief. The bottom line is that it is best to have several magnification choices so you can optimize the view.
