Depending on how fussy you are about having a completely clean image across the visual field, if you have a lower focal ratio scope you will want to look for eyepieces with a reputation for being better corrected in low focal ratio scopes. When I had a 6mm Kellner, I found the eye relief annoyingly short, sure, but when compared to the 6mm Plossl that often comes with eyepiece kits, it was luxurious. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Stargazing Help came into existence when some young minds got mesmerized by outer space while camping.

Kellners tend to have narrower apparent fields of view (40 degrees rather than 50 or 52 degrees in a Plossl), and in short focal length telescopes (focal ratio f/5 or shorter) they can have more false color fringing, but for the most part it is hard to notice the difference between a well-made Kellner and a well-made Plossl in terms of image quality. still, i somehow managed to avoid the eyepiece pitfalls when buying used off ebay.
