All focal lengths offer 50 field-of-view except the 40mm which offers 42 These "other" ones I speak of, aren't technically that, they are a 5 element eyepiece, of a different design. I dont think so. This type of design also helps provide for eye relief; its a better experience if your eyes. So plan this into such a purchase. Have Any Astronauts Been Lost in Space Forever. 1:10 . But the longer FL units are certainly useful. Meade went back to the drawing board and they removed the fifth element, keeping the original Plossl design, however, they kept the Super Plossl brand and added some premium materials. If that is the case, it will give me another reasonably good, inexpensive zoom to recommend to beginners. For modern eyepieces, the differences between Plossl and Super Plossl is going to depend on the manufacturer. Over time, you will likely spend more on eyepieces than on the telescope.

Each eyepiece gives you a unique magnification based on the formula listed at the start: Why do you need more than two eyepieces? Very often, those eyepieces will be in the outdated 0.965 format rather than the modern 1.25 or 2 diameter barrel format. To estimate the highest practical magnification for your telescope, you take the aperture in millimeters, mm, and multiply it by two. Non-eyeglass wearers can usually tolerate Plossls as short as about 10-12mm before their eyelashes start brushing the ocular lens. What Is A Plossl Eyepiece?(Thoroughly Explained!) - Scope The Galaxy 32 mm = 18.75X12 mm = 50X8 mm = 75X6 mm = 100X4 mm = 150X3 mm = 200X.

Super Plossl eyepieces are generally a little smaller than this at around 16-20 mm in size, which is why theyre sometimes referred to as wide-angle or low power plossls. The view being presented to your eye in a low power eyepiece minimizes everything from optical aberrations in the telescope, to distortions from thermals or atmospheric conditions. There are certainly much better options out there but at a significant cost. Suggesting an F6 scope becomes an F18 would also imply things like reduced CA in a refractor. Lower power almost always looks better than higher power. This four-element Plssl design is the most popular eyepiece optical design that gives you excellent image quality, good eye relief, and a 50 to 56 degrees apparent field of view.

Simple Plosels work well and unless you have money burning a hole in your pocket, I would start with simple affordable eyepieces. Kellner eyepieces use three glass elements in two groups to minimize color fringing. So your 600 mm example (f/6) becomes, in effect, an 1800 mm focal length, f/18 but it does not change the focal length of the eyepiece. And, in general terms, the higher the AFOV, the harder it is to make an eyepiece that will present a good image all across the field of view, which also drives up the cost. I am not aware of an ES branded 70 degree series in the USA, but they do have a Bresser branded 70-degree series. As I mentioned earlier in the article, not all Plossls are created equal, which simply means that there are good Plossls and then there are bad Plossls. But what are the differences between these two and how do you know which one to choose? The sharp/crisp view you get from your 40mm Plossl comes down to the relatively low magnification it provides. Or is this overkill and am I better off saving money and going forward something like the Celestron Zoom?

Is there anyway you could include links to the eyepieces you mentioned in the last paragraph of your reply as Im totally new so worried about buying the wrong thing! But for the targets requiring higher mag Im still undecided between: The atmosphere is typically the limiting factor as we get to higher magnifications. You are looking through a LOT of atmosphere which distorts the image. It uses two symmetrical pairs of glass elements (one convex and one concave) to pass the light. You can build a full set of these with good results, but be aware of eye relief, especially if you wear glasses. It's one of the best choices you have when it comes to budget stargazing.
