A 15mm focal length eyepiece with a huge 82-degree field of view, equal in this respect to the famous Nagler eyepieces. Luminos is a 7-element design enclosed in an anodized aluminum body. A rubber ring is placed on the eyepiece allowing for a firm grip. This is probably one of the cheapest eyepieces with such a large field of view on the market. The distance between the exit pupil and the eyepiece is 17mm, which guarantees appropriate comfort of observation. The eyepiece has a standard 1.25" filter mount.

Luminos series eyepieces provide a very well corrected image even in telescopes with a light intensity of about f/5.

The 15mm focal length allows you to observe various types of objects. In most telescopes, this eyepiece provides medium magnifications useful for viewing the sky. For example, in Dobsonian 8, this eyepiece will provide 80x magnification with a real field of view of about 1° - with these parameters, we can attempt to observe numerous deep sky objects, such as star clusters, planetary nebulae or distant galaxies. All Luminos eyepieces are mutually parfocal and do not require a significant change in focus when changing the eyepiece in the telescope's extension tube.
