Baader Classic Ortho Eyepieces 6 mm, 10 mm and 18 mm: classic sharpness for Moon and planets<\/strong><\/h2>\n\n\n\n

The orthoscopic eyepiece design has been around since the nineteenth century and is still used for a simple reason: few lens elements mean little light loss and maximum contrast. The Baader Classic Ortho series combines this classic design with modern multi-layer coatings.<\/p>\n\n\n\n

You choose a Classic Ortho if sharpness is more important than a wide field of view. When observing the moon, planets, and double stars, every detail counts, and that is precisely where these eyepieces excel.<\/p>\n\n\n\n

Three focal lengths<\/h4>\n\n\n\n

The series is available in 6 mm, 10 mm and 18 mm. The 18 mm is a fine wide-field eyepiece for the moon, the 10 mm an all-rounder for planets, and the 6 mm gets the maximum out of your telescope under good seeing conditions. All three have an apparent field of view of 52 degrees.<\/p>\n\n\n\n

Simplicity as power<\/h4>\n\n\n\n

The four-element design provides neutral color reproduction and a dark sky background. The eyepieces are light and compact, so the balance of small telescopes is not disturbed. The barrel is 1.25 inches (31.75 mm) with a standard filter thread.<\/p>\n\n\n\n

Featured accessories<\/h3>\n\n\n\n

Combine a Classic Ortho with a Baader Barlow lens to get extra magnifications from the same eyepieces. A moon filter subdues the bright moonlight at low magnification.<\/p>\n\n\n\n
