Celestron X-CEL LX 9mm望遠鏡アイピース - 93423

I’ve been using this 9mm eyepiece for a few weeks now, and the sharpness on Jupiter’s bands is noticeably better than my old kit lens. The 60-degree apparent field makes it easy to keep the planet centered, which is a huge plus for higher magnifications.

For planetary viewing the 9mm focal length really brings out crisp detail on Jupiter’s bands. The twist-up eyecup stays put even when I'm wearing glasses.

The 60-degree apparent field of view makes a real difference; Jupiter's bands were crisp and sharp right to the edge. I was surprised how comfortable the long eye relief is, even with glasses on.
