Tele Vue 13mm DeLite 天体望遠鏡用アイピース - 1.25インチ - EDE-13.0

The view through this 13mm is incredibly sharp from edge to edge, makes Jupiter's bands look like they're drawn with a fine pen. My only slight complaint is the 20mm eye relief takes a little getting used to if you wear glasses, but once you find the sweet spot it's a perfect medium focal length.

Finally, an eyepiece that gives me comfortable eye relief even with glasses on; the view stays sharp and perfectly clear across the entire field. The 62-degree apparent field feels just right for framing planets without losing that immersive look.

I've been using this 13mm eyepiece on my Dobsonian for a few weeks now, and the sharp, crisp views of Jupiter's bands and moons are fantastic. It really lives up to the hype for medium focal length work.
