are plossl eyepieces good
I have not had an opportunity to test it yet but the general discussions have favorable. 1:10 . It also gives the widest possible exit pupil in my dob and SCT, very handy when using nebula filters. Optics manufacturers began selling and popularizing Plossl eyepieces, albeit with a generally simplified design where each achromatic doublet had the same focal length. Rating (max 5): The telescope comes with a 2x Barlow so I was thinking of getting one of the zooms you recommended. To achieve these benefits, they may use special glass and more costly manufacturing. The magnification range that is appropriate to your scope. These low-quality Plossls lack an internally blackened lens barrel with thread baffles and blackened lens edges and sophisticated anti-reflection multi-coatings, all of which are a necessity to produce an excellent image. They deliver sharp images in almost all telescopes. Many brands of eyepieces are available, including SVBony UltraWide, Astromania UltraWide Angle, Agena Astro StarGuider Enhanced UltraWide Angle and others. Now we can establish a target magnification range. Plossl eyepieces are often included in better telescope packages as the starter eyepieces.

You mentioned regarding ORTHO eyepieces: Excellent specialty eyepieces, usually for planets. The price can run to over $1000 per eyepiece. but the meat of the article is about understanding the considerations and specifications to know when selecting eyepieces. I purchased the Celestron Starsense 102mm refractor, focal length 660mm, stated highest useful magnification is 240x; it should arrive in about 2 weeks. Because of this setup, you might also hear a Plossl eyepiece referred to as a symmetrical eyepiece. Features : 5 superior-grade Plossl eyepieces: 1.25-in, 4-element design with a 52 AFOV (32mm has 44)4mm, 6mm, 9mm, 15mm, and 32mm . Im fairly picky so would extend budget for better eyepieces if its worth it. You can use the same eyepiece on planets and deep-sky objects (DSOs). You noted eye relief is important for those wearing glasses. I started with the Celestron zoom. I recommend it often to beginners on a tight budget. 3. I was just wondering if plossls are still worth it or should get a better eyepiece in a 30mm range. .

This type of eyepiece provides you with wide-field views without any distortion due to its use as an achromatic lens system which reduces chromatic aberrations by combining two lenses made from different types of glass materials together on each surface. Stargazing Help is a participant in Amazon Associates program. What happens if you use an eyepiece that has a the wrong exit pupil? Generally, Plssl eyepieces are best suited to Newtonian and fast telescopes. This determines how much light the telescope will gather. The biggest advantage is much better ER in a large ocular. In terms of eyepieces, my best advice is provided in the article. I possess an embarrassing array of fine eyepieces with names like Ethos and Nagler and Delos.

It appears to be a custom-made 90 degree binocular built from two 90 degree diagonals and binocular-size objectives attached in place of the usual OTA. At shorter focal lengths they have less eye relief, and at all focal lengths they have a narrower field of view, than newer types. There are certainly much better options out there but at a significant cost. Get to know more about us here. Meade telescope maksutov eyepiece ETX-105EC Super Plossl 6.4mm 1.25" w capsule.

As you learn more about astronomy and you gain more experience with time, you may want to move to Plossls or even higher-quality eyepieces. This also makes them more resistant to any form of dust getting inside the eyepiece. Super Plossls offer a smaller field of view, which makes them good for close-up views and examining small objects. However, some eyepieces have an eye relief as short as 5 mm. But, if you have a plan, you can fill in those slots, working toward a well-balanced set of magnifications. They have a 60deg apparent field, long eye relief, adjustable eye shield and extremely well corrected.

These are two very important considerations when you are looking for eyepieces. 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. there are of course options to plossls which are about the same prices as GSOs such as the BST Discoveries and TMB type eyepieces (new from Skies the Limit on Ebay) which have a wider field and better eye relief than plossls and are probably as good as most things non-premium. The Japan made 16mm Meade 3000 was a very nice medium power plossl and the 40mm in that series was surprisingly nice as well. Lenses are fully multi-coated for excellent light transmission and reduced internal reflections. The Plossl is a good all-around eyepiece design, is well suited for generic use and is relatively inexpensive to make. the reality is that today's eyepieces are all quite good, particulalarly in an f/10 telescope. If your scope uses eyepieces that are closer to 1, then you have an old style .965 that is now obsolete. I hope I can say that someday. Where a difference can show up is that a lower number focal ratio scope will make it harder for an eyepiece to provide a uniformly good, in-focus image all the way across the field of view due to the steeper angle that the light arrives at the edges of the eyepiece with a low focal ratio scope, as compared to a high focal ratio scope. Thanks. Of course, for the cost of the two Plossls, you could justify having them as spares or outreach EPs. There is the 56mm Meade Plossl which magically turns my short FL refractors into their own finder scopes. The Plossl eyepiece is a four-element design consisting of two doublets. Even when I upgraded to a 6mm Goldline, I kept the Kellner around because of pretty annoying kidney-bean blackout issues on the Moon with that eyepiece. 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. Once we are done, they will make sense. How does that field of view impact the viewing experience? Many thanks, Sophie. Save my name, email, and website in this browser for the next time I comment.

Thinking in a super ploss 32mm and maybe something between 9mm and 15mm . 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.

PayPal, cash, bank transfer are all acceptable. I often had to drop back to about 180X because of poor seeing and transparency. I have to say that your questions are answered in the article.

If there is a local club, I would suggest you visit and consider joining. In the next section, we will talk about the AFOV of an eyepiece. However, I have eyepieces that have larger exit pupils than 7 mm and they work well. This is why we recommend you try to locate the object first at low power, then use a higher magnification if you likethe wider field of view on the sky provides more context in terms of asterisms and reference stars and makes it more likely that youll catch the object you are looking for. The big problem with Plssls is that the eye relief is about 0.75 times the focal length. Excellent article, thank you very much for taking the time to publish it. Hi, I have recently bought a Orion XT8 and am trying to work out which eyepieces to add to what is provided with the scope.
