A decent barlow might cost as much or even more. However, if you want to optimize your viewing experience, youll need to invest in a better-quality eyepiece. Non-eyeglass wearers can usually tolerate Plossls as short as about 10-12mm before their eyelashes start brushing the ocular lens. While it covers the same range as the Celestron zoom, it offers better optics, better mechanical operation, and a wider field of view. The components of a Plossl eyepiece are the two groups of lenses. When you are shopping, if you need long eye relief, make sure you are selecting the correct ones. This doublet design has an apparent field of view of 50-degrees or wider but can suffer from short eye relief making them difficult to use for some . Many Kellners are made with field stops opened up to 50 degrees, in which case it can truly compare to a Plossl in any telescope with a focal ratio of f/6 or slower. To achieve a maximum of 200X (2X the aperture of 100 mm), we solve for the focal length. 14 = 128 = .6 The Plossl eyepiece is a type of optical system that was invented by Ernst Abbe. Quality this good usually costs a lot more. Also, atmospheric conditions can limit how much magnification you can use on a given night. https://telescopicwatch.com/best-telescope-mounts-for-astrophotography/, https://telescopicwatch.com/best-astrophotography-telescopes/, https://telescopicwatch.com/best-barlow-lens-and-how-to/, https://telescopicwatch.com/celestron-8-24mm-zoom-eyepiece-review/, https://www.amazon.com/Orion-8879-1-25-Inch-Enhanced-Telescope/dp/B000BMPBLK/ref=sr_1_8?crid=3KKUJRXYYN7DI&dchild=1&keywords=telescope+diagonal+1.25&qid=1610887695&sprefix=telescope+diagonal%2Caps%2C512&sr=8-8, https://telescopicwatch.com/orion-skyquest-xt8-intelliscope-review/, https://www.rothervalleyoptics.co.uk/baader-hyperion-mark-iv-8-24mm-universal-zoom-eyepiece.html, https://www.amazon.com/s?k=Orion+Q70&ref=nb_sb_noss_2, https://telescopicwatch.com/best-telescope-eyepieces/, https://www.amazon.com/Orion-8829-Wide-Field-Telescope-Eyepiece/dp/B000M89H7C/ref=sr_1_2?dchild=1&keywords=Orion+Q70&qid=1606584502&sr=8-2, https://www.amazon.com/Explore-Scientific-68%C2%B0-40mm-Eyepiece/dp/B007LMG3F6/ref=sr_1_1?dchild=1&keywords=explore+scientific+68&qid=1606584676&sr=8-1.

Since there are so many different types of eyepieces available on the market, choosing the right one for your situation can prove to be a harrowing task. However, I have eyepieces with much smaller exit pupils and they work fine. Are plossl eyepieces still worth it? Plossls provide very good eye relief for eyeglass wearers in focal lengths of about 25mm and longer. Your email address will not be published. I need some eyepieces with long FL for low magnifications. Those are significantly more expensive than the 1.25 focal lengths. I had one and sold it. I started with the Celestron zoom. Do you have any additional comments to help me? Pentax 10.5mm Eye Piece Excellent Condition (#314374986239) r***d (1910 . Better edge correction with a short-focus telescope is one of the things you pay extra money for, and sophisticated eyepiece designs have as many as eight elements. IF you like your Hyperions , you could get a 2 inch visual back and 2 inch diagonal / or 2 inch SCT diagonal and add the 31 or 36 Baader eyepieces in 2 inch . 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. My other eyepieces, ES and Meade 82 degree, stayed in the eyepiece case most of the time. 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. Orion Q70 38 mm works well. 4. Modified vs Unmodified DSLR Astrophotography: The Ultimate Showdown! Consider something between 35 and 40 mm in focal length with an AFOV of 65 degrees or wider for your lowest power eyepiece for your telescope. Here we focus on becoming a knowledge hub for astronomy and astrophotography enthusiasts. However, I have eyepieces that have larger exit pupils than 7 mm and they work well. Can you give me any specific recommendations on what to buy and from where? I guess my curiosity is mostly about the diagonal. I have a custom-built 32mm Plossl that has been opened up as wide as possible to 60 or 70 degrees, for use as a 2 eyepiece, although in my 10 Dobsonian at f/5 the edge distortions prevent it from seeing much use. Of course, for the cost of the two Plossls, you could justify having them as spares or outreach EPs. As for Barlow Lenses, take a look at this article. As a kid, I loved looking at the moon (which can be seen any time of day, regardless of ones bedtime) so make sure that the field of view is wide enough to see the whole shebang. Free shipping for many products! 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. It was named after Peter Barlow who invented it in the 1800s, so it is usually capitalized. Because of this setup, you might also hear a Plossl eyepiece referred to as a symmetrical eyepiece. If that surface is wobbly the scope will be almost useless. In the next section, we will talk about the AFOV of an eyepiece. Quality this good usually costs a lot more. Any exit pupil between 7 mm and .5 mm is just fine. It also produces an erect image, meaning you see what youre viewing rather than seeing everything upside down or sideways as some types do. Now we can establish a target magnification range. Like going from a 32 TV to a 65? I am very interested in viewing Nebulae do you think this set up will work well for that or do I need other eyepieces or filters?

Plssl eyepieces are affordable and they're outstanding additions to amateur telescopes. 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? Both solutions offer somewhat similar mag-fov-er-price. (Focal ratio is a term that refers to the telescopes focal length divided by its aperture. Look at the apparent field of view specs and understand what this means for the field of view.

I've got a one-off plossl like that in my kit that I'll probably never sell, (aside from my 5 element ones) and it's one that is rarely seen. If you do upgrade, youll probably want to go for a different eyepiece design than a Plosslsomething with a sharper image or a wider field of view or a longer eye relief (or all three.). However, some eyepieces have an eye relief as short as 5 mm. The Baader offers wider fov, but at quite the price premium. Very often, those eyepieces will be in the outdated 0.965 format rather than the modern 1.25 or 2 diameter barrel format. The Big Bang Optics is compensated for referring traffic and business to these companies. However, because they have more glass elements than other designs, like Kellners, their manufacturing becomes extremely important to get high-quality optics. So speaking of the Barlow as if it modifies the FL of the eyepiece, while technically not correct, does provide an easier model to understand the net effect. This determines how much light the telescope will gather. Thanks all. A four-element eyepiece was made by putting together two achromatic doublets with different focal lengths. I hear that, sometimes you find one that is sweeter than others. The Hyperions work well in SCTs and you can't beat that large eyelens and eye relief ,JMO.

The basic design hasnt changed much, but the real costs of manufacturing have dropped. Youd have to look into more complex designs which include a barlow lens, or simply use a longer focal length eyepiece with a quality barlow.

I am looking for as much as best I can buy. I foolishly destroyed it while experimenting with solar projection, because I hadnt realized the metal-and-glass construction was aided by a plastic retaining ring on the field stop, and I hadnt realized you do not need to change the eyepiece focal length when doing solar projection. Or is this overkill and am I better off saving money and going forward something like the Celestron Zoom? Newer multi-coatings are better, I suppose, but newer does not always mean better in the ocular game. At that price point, it couldnt compete with other 5-element devices like Erfle and Nagler eyepieces that had better performance.

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.
