In case anyone hasn’t noticed, Celestron has slipped in a new focal length to their Ultima line. If you go to Astronomics web site you’ll see a 10mm. Notice also that it has a lower barrel with a Tele Vue style undercut. What I’d like to see them do is pick up the other focal lengths that I know these “Masuyama” design eyepieces are available in such as the 20mm and 25mm.
