If you had to choose 1 low-power 2 EP for chasing deep sky objects (again, at 600mm f7.5), what size piece would you go for? If your telescopes focal length is different, just change the focal length in the formula. I often recommend the use of a barlow to achieve the higher range of magnifications. This is the link to the eyepiece I am looking at potentially buying, would you recommend this over the Orion one or vice versa do you think?

Meade 4000 Super Plossl - any good? - Discussions - Eyepieces You can use the same eyepiece on planets and deep-sky objects (DSOs). (Focal ratio is a term that refers to the telescopes focal length divided by its aperture. 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.). I also struggled to see features on both (gas bands on Jupiter and clear rings on saturn). 14 = 128 = .6 What Is A Barlow Lens For A Telescope?
Vixen NPL Eyepieces | First Light Optics 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. If well made, Plossls are bright, with good contrast, and a flat field, and excellent sharpness. So, I think it worth your while to try the Plssls. At 32mm, a Plssl will give you as wide a field of view as any 1.25mm eyepiece can. They have a pop-up eye guard and they are threaded to accept filters. 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. Plossls are extremely versatile and can be used for all use cases. Understanding and using a Barlow Lens Save my name, email, and website in this browser for the next time I comment.

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. However, some lateral color error is apparent when looking at bright subjects, such as Jupiter or Venus, against a dark sky. To determine a magnification range, we will start with the aperture of the telescope, the size of the front lens, or the mirror in the back. Most telescopes come with one or two eyepieces, which gives you one or two magnification options. Good quality. 32mm (20x & 40x). thanks for all your help. I believe the 5000 UWA's are good as well. But I think you will feel more confident about your purchases and be less likely to be disappointed if you read through the guide.

The 5-lens-element pseudo-Masuyamas that telesonic mentioned are/were fine eyepieces. Every new skill takes time. The biggest advantage is much better ER in a large ocular. Plossl telescope eyepieces are the most popular type of eyepiece on the market. Nice, thank you again for the additional inputs. Fully coated with magnesium fluoride on every air-to-glass surface for excellent light transmission and high contrast views. A Kellner eyepiece has 3 lenses, while a Plossl has 4. We can see that 2 eyepieces have an advantage over 1.25 eyepieces when designers are making wide-view eyepieces. 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 . For example, if you put a 30 mm eyepiece in a 3X Barlow, it will triple the magnification you get from that eyepiece. 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. Since it's such a popular eyepiece and allows for quality, planet-viewing, that makes it a great instrument for attracting newcomers to the hobby, especially children. There was an old Meade Super-Plossl design that used an additional lens element and could reach a wider field of view.

Orion Sirius Plossl eyepieces are ideal for any type of telescope; refractor, reflector, or catadioptic. Offering a wide 43 apparent field of view, this 40mm Orion Sirius Plossl Telescope Eyepiece provides extremely sharp images of impressively high contrast. Comparing Orion Telescope & Binoculars options, it appears that a Kellner can be found for almost half the price of a Plossl of the same focal length, although there are also equally cheap Plossls available from various sellers on Amazon that are highly comparable. I have seen wider-field Plossls. The longer FL Plossls (>15mm) have some distinct advantages over more complex designs without the major disadvantage of Plossls which is short ER. Kellner eyepieces, on the other hand, are generally pretty close to each other in terms of quality so theres little chance you will get much variance in image definition between brands. That is why I suggest, if you can use 2 eyepieces, you will want one or two low power wide view 2 eyepieces. I guess my curiosity is mostly about the diagonal. Typically a Barlow does not add or subtract from this, but there again we have bad Barlows and Good Barlows.

Later in the article, I will also give my top recommendations for both the best Kellner as well as the best Plossl eyepieces. Brilliant article and I thank you for it, I was literally really confused prior to reading it. Generally, to maximize the number of stars you see in an eyepiece with a given telescope, both the magnification and field of view should be maximized. Another useful aspect of a wider field of view is that, assuming the entire eyepiece is sharp enough to show good images right to the edge, you dont have to nudge the telescope to track the rotation of the Earth as often with a Plossl (50 degrees) compared to a Kellner (40 degrees). This will give you a lower power and a medium to high power eyepiece, depending on the focal length of your scope.
What Is a Plossl Eyepiece - Planet Seekers With a 130mm-F5 I would use a Plossl 32mm for its low-mag-wide-view. Thanks for your comment.
