TeleVue Pl\u00f6ssl 15mm : 50\u00b0 1,25″ Oculair: klassiek Ploessl-oculair van TeleVue<\/strong><\/h2>\n\n\n\n

The TeleVue Pl\u00f6ssl 15 mm is the mid-magnification eyepiece of the series and, together with a Barlow, the core of many eyepiece cases: directly a 15 mm, with a 2x Barlow a 7.5 mm.<\/p>\n\n\n\n

The high-contrast, flat image makes it equally suited for the Moon as for brighter deep-sky work.<\/p>\n\n\n\n

The TeleVue Ploessl design<\/h4>\n\n\n\n

Four lenses in two groups are all a good Ploessl needs. Because there are few glass surfaces, transmission remains high and contrast is maximized: precisely the characteristics that matter for planetary and lunar observation.<\/p>\n\n\n\n

TeleVue T-type optics brought the design to the current level in the seventies, with tight manufacturing tolerances, multiple coatings, and blackened lens edges. You can see the difference compared to a standard supplied eyepiece right at the edge of the field.<\/p>\n\n\n\n

The pivot of a small set<\/h4>\n\n\n\n

Two Pl\u00f6ssls and a Barlow cover four magnifications. The 15 mm is almost always the first choice among them, because both the direct and barlowed magnifications fall into the most used range.<\/p>\n\n\n\n

The eye relief of approximately 11 mm is generous for a Pl\u00f6ssl and makes longer sessions comfortable.<\/p>\n\n\n\n

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

In a telescope with a 1200 mm focal length, this eyepiece yields about 80x with a true field of view of approximately 0.61 degrees. For your own telescope: true field of view = 57.3 x field stop divided by the focal length of the telescope.<\/p>\n\n\n\n

The effective field stop of this model is approximately 12.8 mm.<\/p>\n\n\n\n

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

A TeleVue 2x or 3x Barlow lens doubles or triples the magnification of any Ploessl eyepiece without any loss of quality; two Ploessl eyepieces plus a Barlow lens thus cover four magnification levels. Models 25 mm and larger also accept the Dioptrx astigmatism corrector.<\/p>\n\n\n\n

For whom yes and for whom no<\/h3>\n\n\n\n
