-Good Eye Relief

Plössl eyepieces are a very popular 4-element design that provides excellent image quality and good eye relief. In Sky and Telescope review, Celestron's Plössl eyepieces were rated the top ranking, and found to outperform many similar, but more expensive eyepieces. Celestron offers these premium eyepieces at affordable prices, yet they are among the best designed and corrected eyepieces available. They are multi-coated (not just fully coated) for enhanced contrast and all are threaded to accept Celestron colored eyepiece filters. Now with rubber grips for easier handling, these Plössl eyepieces have been improved even further. Plus, soft rubber eyecups create a more comfortable viewing experience while blocking out auxiliary light and providing increased contrast. An exceptional value.

Celestron NexStar Plossl 13mm
I initially bought this eyepiece to be used in a Celestron C102-HD. The C102-HD is an achromat and thus I expect some chromatic abberation when I look at bright objects. The 13mm NexStar just show much more chromatic abberation than both my 15mm Antares Ultra Plössl (same as ultima/ultrascopic) and my Meade 9.7mm series 4000 plössl. Also the eyecup is placed so far out that it's impossible to view the entire FOV at once, you'll have to remove it (which btw is easy and reversable). Recently I've bought an 8" f/6 newt which work much better with the 13mm NexStar. When viewing epsilon lyrae it was just as sharp on axis as the Ultra Plössl (80x) and the extra bit of magnification (92x) was just enough to split epsilon1 (eps2 was strongly elongated...).

Celestron NexStar Plossl 13mm
Good optics - but the eye relief is getting a little short. The 13mm is the highest power in the Plossl line that I'm willing to use due to the short eye relief - even without glasses.
