TeleVue Panoptic 35mm: 68\u00b0 Wide-angle eyepiece: Panoptic eyepiece with 68-degree field of view<\/strong><\/h2>\n\n\n\n

The Panoptic 35 mm has been the standard wide-field eyepiece in the series for decades. The 38.7 mm field stop provides a true field in which entire star clusters and large nebulae fit with their surroundings.<\/p>\n\n\n\n

The 24 mm eye distance also makes it fully usable for people who wear glasses.<\/p>\n\n\n\n

Why 68 degrees<\/h4>\n\n\n\n

The Panoptic series is TeleVue's answer to the demand for a wide field without the weight and price of the 82- and 100-degree designs. The 6-element design also corrects the edge of the field in fast telescopes, providing a flat image all the way to the field stop.<\/p>\n\n\n\n

The name is a portmanteau of panoramic and optics. In practice, 68 degrees is the point where the field feels spacious while the eyepiece remains light and compact.<\/p>\n\n\n\n

Overview with focused magnification<\/h4>\n\n\n\n

Compared to the 41 mm, the 35 mm gives a slightly smaller field at a higher magnification and therefore a darker sky background. Under a sky that is not perfectly dark, that is usually the better trade-off.<\/p>\n\n\n\n

Note the exit pupil: 35 mm divided by the focal length of your telescope. At f\/5 you get 7 mm, the upper limit of what a dark-adapted eye can use.<\/p>\n\n\n\n

In your telescope<\/h4>\n\n\n\n

In a telescope with a 1200 mm focal length, this eyepiece provides approximately 34x with a true field of view of about 1.85 degrees. For your own telescope: where field of view = 57.3 x field stop divided by the telescope's focal length.<\/p>\n\n\n\n

The effective field stop of this model is 38.7 mm.<\/p>\n\n\n\n
