I often recommend the use of a barlow to achieve the higher range of magnifications. You can add the specialty single FL eyepieces later if you wish. In this article, we will only focus on the differences between Plossl and Kellner eyepieces. As Im sure you know, a Barlow actually narrows the cone of light that enters the eyepiece, hence it affects the apparent focal length and thus the f/ratio of the telescope objective. One last thing, as a kid I used my telescope to watch squirrels and birds (which was interesting because the image was flipped around :-) so, you might consider getting an eyepiece that flips things the right way around so that navigating terrestrial nature is easier to manage. There is no problem using a Celestron eyepiece in a Meade telescope, for example. They are also really sharp. You can use the same eyepiece on planets and deep-sky objects (DSOs). These "other" ones I speak of, aren't technically that, they are a 5 element eyepiece, of a different design. I see that there are some optical limits to how wide an FOV a 1.25 EP can manage at bigger (like 32mm) focal lengths. As we go up in price range, we gain capabilities that may not be immediately obvious. Higher priced eyepieces usually include more elements in the optical path that are there to help reduce or eliminate aberrations that can be seen around the edges of lower cost eyepieces. If you are a glasses wearer and plan to keep your glasses on while you are observing, then you will likely want eyepieces with at least 17 mm of eye relief, and some glasses wearers prefer at least 20 mm.

We have a range of 32 mm to 3 mm. Required fields are marked *. At one time Plssls were premium eyepieces. For astronomical observations, such as viewing craters on the moons surface from Earth, high-magnification models are preferred because they offer more detail. - 32mm plossl. The tradeoff was that each lens surface added another internal reflection, reducing contrast and adding glare. Despite the narrow field of view and short eye relief, it showed shockingly good views of Saturn, Jupiter, and even the Moon. I usually recommend a 32 mm Plossl type eyepiece as that provides about the widest view you can achieve with a 1.25 focuser.
