These will normally be higher priced and may be outside the price range we show here. The result in magnification is the same and the eye relief associated with the eyepiece is retained or, in some cases, actually lengthened a bit. Focus on the magnifications rather than the mm of the eyepieces. Thanks for your comment. 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, Excellent article and very good recommendations.

A Televue Plssl may be better than a generic one, but the difference is probably not worth the additional cost. For astronomical observations, such as viewing craters on the moons surface from Earth, high-magnification models are preferred because they offer more detail. Plossl eyepieces are often included in better telescope packages as the starter eyepieces. Plossl vs Kellner Eyepieces. - Little Astronomy So you ended up with: But, if you have a plan, you can fill in those slots, working toward a well-balanced set of magnifications. The eye relief is the distance between your eyes and the eyepiece where you are able to view the whole image comfortably. The larger barrel allows them to create an eyepiece with a higher AFOV. Over time, you will likely spend more on eyepieces than on the telescope. Do you think it would be sensible for me to look at getting a higher magnification specific eyepiece? In the case of the Celestron, you get all the focal lengths from 24 to 8mm in one eyepiece that costs $100. What is a Plssl eyepiece? | BBC Sky at Night Magazine Many brands of eyepieces are available, including SVBony UltraWide, Astromania UltraWide Angle, Agena Astro StarGuider Enhanced UltraWide Angle and others. But the longer FL units are certainly useful. Offered in both 2 and 1.25, these are excellent eyepieces. 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. These are highly sought after ep's, and hold their value well. If you don't like the reflections, there really aren't many other budget options at its focal length beside a Plossl which will be super uncomfortable to use, or spending over $100 for something like a Meade UWA. Celestron Telescopes Reviews: Should you buy? - Little Astronomy You can enjoy wide-angle views without giving up any of the clarity or sharpness when using Plossl eyepiece while Kellner will give you more magnified views but at less than half the brightness levels in comparison to other lens designs on this list if light pollution was involved. Look those up, seeing and transparency in the context of astronomy. a Celestron 8-24 Zoom with a 2x Barlow Also, atmospheric conditions can limit how much magnification you can use on a given night. But the one I am recommending here is the Tele Vue Nagler series. I generally use my 40 to search for DSOs so Ill probably replace that one at some point too.

I am considering buying another eyepiece, maybe 6mm, and a Barlow, maybe 2x, to give me a wider and higher range of magnification. Yes, the wider field of view of a Plossl is very helpful, but 40 degrees of Kellners isnt a soda straw (unless you are used to looking through very wide field eyepiece. However, the BH Zoom is by far my most used eyepiece. In comparison, Aspherical lenses generally have no color distortion but might not work out well if the telescope user needs really high magnification. Non-eyeglass wearers can usually tolerate Plossls as short as about 10-12mm before their eyelashes start brushing the ocular lens. This might contain more of what you need. A common problem are eyepiece kits, which are big boxes that some telescope suppliers will sell you with half a dozen eyepieces, most of which include annoyingly short focal length Plossl eyepieces.

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. Focal length telescope / focal length eyepiece = magnification or power. As of the past couple years, it seems possible that the choice between Kellners and Plossls has been made for usyou either get what you get with your beginner telescope, or you will have to find a Plossl.

This wider field of view will make it easier to find your targets, allow you to view larger deep-sky objects, and provide a more immersive experience for everything that you view. Because the eyepiece was still similar enough to a Plossl and still kept the symmetrical design, they called it Super Plossl. What Is A Barlow Lens For A Telescope?

Note that the price categories are approximate, as prices can vary between retailers. In that respect, they are similar to the Explore Scientific 82 degree mentioned earlier. The longer FL Plossls (>15mm) have some distinct advantages over more complex designs without the major disadvantage of Plossls which is short ER. The one exception I would keep in mind would be when working with Newtonian reflector telescopes below F5. At one time Plssls were premium eyepieces. Do you need to have the best to enjoy astronomy? The 66-degree AFOV of the Gold Line series provides a 32% wider field than Plossl eyepieces. Here we have very good eyepieces with some extra features. I agree. I think some of these kits even include 4mm eyepieces, and thats ridiculous! 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. 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. 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? In your case, I would do this for the 30 and the 20. https://telescopicwatch.com/best-telescope-mounts-for-astrophotography/, Then you look at the optical tubes. A good modern eyepiece like a BST starguider 12,8 and 5mm are excellent eyepieces. Plossl eyepieces are often included in better telescope packages as the starter eyepieces. We have compared Plossl against Kellner eyepieces in a previous article. Interesting points Philip. Orion 12 mm Sirius Super Wide Angle Correct Image Eyepiece has a rubber eyecup that holds in light, which enables you to enjoy this powerful telescope eyepiece at night without glare or reflections from any external sources.
