are plossl eyepieces good

At shorter focal lengths they have less eye relief, and at all focal lengths they have a narrower field of view, than newer types. (Compare, for instance, 20mm of each type, or 10mm of each type.) This was very useful, I got a meade infinity 90mm ( after read the review here -. So I sincerely hope that this article helps you understand the similarities and differences between Plossl and Kellner eyepieces so that you can an informed decision and choose the best one for yourself. https://telescopicwatch.com/best-telescope-mounts-for-astrophotography/, Then you look at the optical tubes. We will now discuss the specifications of eye relief and apparent field of view. It had one of the best fields, edge to edge, in my SCT that I've ever seen. Each eyepiece gives you a unique magnification based on the formula listed at the start: Why do you need more than two eyepieces? If we look at the range I provided above, we see that we could replace several eyepieces with one zoom. Again, it only costs $30 to $40 to find out, so the education is not that expensive. I really enjoy usingPlssls. A large field lens makes the ocular easy to look into. Here's the short answer - Plossl eyepieces are generally better than Kellner eyepieces, but they also tend to be more expensive. Just search on Astronomy Club and you will probably find one in your area. Put the zoom on the Barlow for the high range. For example, if you put a 30 mm eyepiece in a 3X Barlow, it will triple the magnification you get from that eyepiece. 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. That is why I suggest, if you can use 2 eyepieces, you will want one or two low power wide view 2 eyepieces. I dont think so. Stargazing Help is a participant in Amazon Associates program. At 32mm, a Plssl will give you as wide a field of view as any 1.25mm eyepiece can. The 66-degree AFOV of the Gold Line series provides a 32% wider field than Plossl eyepieces. But, at least get the 32mm Plssl. On the inside, they are exactly the same design. There is no problem using a Celestron eyepiece in a Meade telescope, for example. Ah I see what you are saying, I had wondered whether this might have had an impact as Ive seen it mentioned before but dont fully understand it so will do some research, thank you . To say it a different way, in general, an F5 scope will place more demands on the eyepiece around the edge of the field of view than an F10 scope. Are Plossl eyepieces good?

Kellner and Plossl- both are two different types of eyepieces for telescopes. EP-mm = magnification = afov It costs three to four times as much as the Celestron Zoom, but if you have the budget, this is the one to get. Well-made lenses are expensive though, so in general the more lenses, the higher the price of the eyepiece. Omni 56mm Eyepiece - 2" Learn More. In your case, I would do this for the 30 and the 20. I had a TV 20mm Plossl once.

Aspheric and Plossl Plossl are both lens designs that can be used in most telescopes. You can still get eyepieces, but there are few choices. I think some of these kits even include 4mm eyepieces, and thats ridiculous! So, I am going to organize the guide around five questions and four formulas. I often had to drop back to about 180X because of poor seeing and transparency. 30 = 60 = 1.3 A Barlow lens is an optical device that goes between the eyepiece and the focuser. A 15mm Plssl might be worth it, if you dont wear glasses. I think Id really enjoy a zoom for all the reasons you mention, But Im having a difficult time assessing how much weight to put on the field of view of given eyepieces. Besides fov, How would you compare the optical quality of the Celestron to the Baader? The "sharpness" you are seeing may well be better explained by the focal length of the ep than the quality of Plossls in general. They are most useful in medium and longer focal lengths for terrestrial, planetary, and lunar viewing. It offers good color correction and high-contrast images. > Click here to jump to the Best Eyepieces section. These are often compared to the higher priced offerings. Thinking in a super ploss 32mm and maybe something between 9mm and 15mm . You could say Super Plossls are not much more than a marketing tactic these days. While many people will stay with and add Plossls to their eyepiece set, I would recommend not going below 10 mm focal length as the eye relief gets quite short.

Lets just say that once you get below F5, it is really hard for the eyepiece to deliver a clean image to the edge. This is where the second formula comes into play. You could base this on 3, 4, 5, 6 or more focal lengths/magnifications. 70 mm scope will have a max of 140X for planning purposes. Differences and Similarities. 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. The tradeoff was that each lens surface added another internal reflection, reducing contrast and adding glare. The BHZ 2 Adapter has threads on it so you can attach filters to it allowing you to use 2 filters with the zoom. These will normally be higher priced and may be outside the price range we show here. These are exceptional eyepieces, and only available on the used market nowadays. This makes them a bit more complex and expensive than other designs, but also gives them a wider field of view, reasonable eye relief, and reduces optic aberrations. For shorter focal lengths, the StarGuider BST series eyepieces have greater eye-relief, so are better suited. Glad you found it helpful. Any 1.25 diagonal should work. 32 mm = 18.75X 16 mm = 37.5X (32 mm eyepiece with a 2X barlow), 12 mm = 50X (If you have a 25 mm that came with your scope, use Barlow for 12.5 mm), 4 mm = 150X (8 mm eyepiece with a 2X Barlow), 3 mm = 200X (6 mm eyepiece with a 2X Barlow), 24 mm = 25X (the low power end of the zoom), 8 mm = 75X (24 mm zoom setting in a 3X Barlow), 2.66 mm = 225X (8 mm zoom setting in a 3X Barlow), True field of view or FOV = Apparent field of view (AFOV) eyepiece / magnification. Lets look at the minimum. 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. The Orthoscopic Plossl eyepiece is for those who are interested in performing close-up work on specimens up to three inches away from them and still get high magnification.

Good evening everybody. For modern eyepieces, the differences between Plossl and Super Plossl is going to depend on the manufacturer. There was an old Meade Super-Plossl design that used an additional lens element and could reach a wider field of view. I need some eyepieces with long FL for low magnifications. And the zoom provides every magnification in that range without having to change eyepieces. Question: would an 18mm Baader Classic Ortho mostly used for Moon and planets loose sharpness and contrast if used with a short F5 telescope like the Celestron Astro-Fi 130? Explore Scientific, like many eyepiece providers, have higher-priced and budget lines. All the rest will likely be 1.25. 3.

If you do not have your Hyperions yet I recommend you wait until you have these and try them out before you buy the Plossls. Generally, dont mess around with solar projection unless youre okay with damaging the instrument. Any exit pupil between 7 mm and .5 mm is just fine. The image quality is very good and the additional field of view and longer eye relief makes them very comfortable to use. Whether it is cars or telescope eyepieces, there are inexpensive ones, upgraded models, and very expensive ones. Under my sky it was rare that I would be able to get over 225X and still maintain a good quality image, except on the Moon. Achromatic vs Apochromatic refracting telescopes. These sizes have become the industrys standard sizes. The basic design hasnt changed much, but the real costs of manufacturing have dropped. If you want a very good eyepiece with a bit wider field of view but are on a budget, these are very good choices. In some cases, the eyepieces are waterproof to protect them from internal contamination caused by heavy dew conditions. Even though both eyepieces are very common in beginner telescopes, it has become harder to find Kellner eyepieces on their own in the last two years, whether they come from a brand name or the original equipment manufacturer or a reseller. Most people will be fairly comfortable with eye relief of 12 mm or higher. Stargazinghelp.com is a knowledge hub for professional and amateur astronomy and astrophotography enthusiasts. I recommend it often to beginners on a tight budget. In 1849, Carl Kellner invented the Kellner eyepiece, which is essentially a Ramsden eyepiece where one lens has been replaced with an achromatic doublet made of two different types of glass. However, some eyepieces have an eye relief as short as 5 mm. When discussing eyepieces, you will hear people comment on how well the eyepiece is corrected.

In most cases, these are eyepieces that are focused on wider AFOV or better correction for low focal ratio scopes. Newer multi-coatings are better, I suppose, but newer does not always mean better in the ocular game. You can use the same eyepiece on planets and deep-sky objects (DSOs). How important a consideration is this when deciding on an eyepiece? Note to spectacle wearers: Plssl eyepieces with 15mm and longer focal lengths are good choices for spectacle wearers. The telescope comes with a 2x Barlow so I was thinking of getting one of the zooms you recommended. It was grueling, because I couldnt even get the entire field of viewI had to keep my eye hovering above the exit pupil. Orion Sirius Plossl 10mm telescope eyepiece 1.25" in very good to excellent 185794462395 Eye relief is the distance from the eye lens to your eyeball, and the higher the better (within reason).

I think I will go for the BHZ because, as you say, I will be able to use it now and into the future. This will become more apparent the wider the AFOV is of the eyepiece, in my experience. Depending on your budget, if you only have limited funds and are just starting to fill out your eyepiece collection I would go with the zoom, then zoom with Barlow. We often end up spending more on eyepieces than we did on the telescope. In some cases, an object is so large (i.e., the Moon, the Pleiades, the Orion Nebula, the Andromeda Galaxy) that a narrow field of view can only show you part of the object, whereas a wider field of view could show the whole object at the same magnification. Such eyepieces are able to offer great performance, i.e., satisfactory degrees of deviations, to about a 50.degree field.
