I got my new 28mm RKE's from SS today: http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/RKE28mm001.jpg These will make a great addition to my bino-viewer pairs, as well as all-around terrific eyepieces (at a bargain price!) and yes, they will provide excellend views for the general public when I am in "outreach" mode. I'm glad to have had the opportunity to re-purchase the eyepeice (at a discount from what I originally paid for them decades ago, including inflation) since I regretably sold my RKE's some years ago. Here's an out-of-focus (sorrry!) shot of my 3 iterations of the Edmund 28mm eyepiece. The modern RKE, it's immediate predecessor, and the original, made from (I assume) surplus governmet- military- optics from Edmund's heyday in the '60's. I love them all, and all provide a similar view. The oldest one uses 2 achromats, while the 2 more recent are Kellners. (RKE= Rank-Kellner-Edmund). David Rank is the designer of the modern RKE. http://i260.photobucket.com/albums/ii24/JethroTull1958/ATM/RKE002.jpg Many modern, wide-field, high-dollar eyepieces have very short eye-relief, along with other characteristics (kidney-bean-effect, amont others) that make them unsuitable for general-public, "novice" viewing. I ask all seasoned observers to take that into account when selecting an eyepiece for the general public. They won't have the eyepiece skills/knowledge that you do. It would be best to select an eyepiece with medium eye-relief and a "medium" FOV when showcasing the heavens to the general public. Make it easy on them while still giving them a good view of the target. Time for the cantankerous, irrascible, and lonely among us to find something else to sh*t all-over because others don't practice the hobby the way they do. YMMV.
