General Features:

  • Lunt flat-field eyepieces are coated with 0.1% anti-reflective coatings – the same coatings we use on our etalons!

  • 1.25″ barrel.  Offered in five focal lengths as well as a Zoom model.

PRODUCT DESCRIPTION

Each Lunt flat-field 1.25″ eyepiece is coated with the same 0.1% anti-reflective coatings as our etalons! The anti-reflective coatings reduce ghosting and glow, and aid in providing a darker background. These eyepieces can be used for nighttime astronomy as well as solar observing.

The Lunt Zoom Eyepiece offers what we feel are the ideal magnifications for the standard focal lengths of our solar telescopes.  It is an ideal first-look eyepiece that will allow you to quickly view the Sun at a lower magnification and then zoom in when you find interesting details.  The Lunt 7.2 mm – 21.5 mm Zoom is a great little eyepiece at a very affordable price point.

    Ella ★★★★★

    The 0.1% anti-reflective coatings really make a difference—stars look crisp and contrasty against a dark background. I’ve used them for lunar observing too, and the flat field is noticeably sharp edge to edge.

    Jason ★★★★★

    I’ve been using these eyepieces for both lunar and solar observing, and the 0.1% anti-reflective coatings really cut down on stray light—the contrast is fantastic. They hold focus well across the field, making extended sessions much more comfortable.

    William L. ★★★★★

    The 0.1% anti-reflective coating is doing serious work—even on a bright full moon, the view stays crisp with zero glare bouncing around. I’ve used them for both solar and night sessions, and the flat field keeps stars sharp right to the edge, which is a huge upgrade from my old eyepieces.
