The "sharpness" you are seeing may well be better explained by the focal length of the ep than the quality of Plossls in general. Lets take a look. 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. Suggesting an F6 scope becomes an F18 would also imply things like reduced CA in a refractor. A Barlow lens will not reduce the CA in a low FR achromat refractor so to speak of it changing the focal ratio would, I think, introduce confusion in most situations. That is the critical factor. I guess my curiosity is mostly about the diagonal. Understanding and using a Barlow Lens We have compared Plossl against Kellner eyepieces in a previous article. This will become more apparent the wider the AFOV is of the eyepiece, in my experience.

If you just want eyepiece recommendations and dont care about the details, Im adding that section right below before we go into the specifications that answer the above questions and make use of the formulas. 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. 30 = 60 = 1.3 Again, it only costs $30 to $40 to find out, so the education is not that expensive.

Required fields are marked *. 32 mm = 18.75X12 mm = 50X8 mm = 75X6 mm = 100X4 mm = 150X3 mm = 200X. I often recommend the 2 in this series as excellent low-power wide view eyepieces, especially in scopes at focal ratios below F8. I hear that, sometimes you find one that is sweeter than others. Best eyepieces for telescopes 2023 | Space You can use the same eyepiece on planets and deep-sky objects (DSOs).

This can be especially helpful in telescopes of focal ratios below F8. No price limit? Other brands have joined and have used the Super Plossl label, but they all keep the original 4-piece design. Thanks all. For astronomical observations, such as viewing craters on the moons surface from Earth, high-magnification models are preferred because they offer more detail.
