Omegon Binoculars Nightstar 20+40x100 Triplet with Variable Eyepieces

£1,140.00

Quick Overview

These large observation binoculars are ideal for low power deep sky observation of larger targets and come with 2 sets of eyepieces, giving 20x and 40x magnification respectively. The triplet objectives supply a good level of colour correction, but it's generally recommended to keep magnifications below 100x, in order to get the best out of them.

Details

With an objective diameter of 100mm, the Omegon Nightstar provides a very bright image and is perfect for observing the night sky. The new three-element design substantially improves image colour - it can therefore be ranked among the half-apochromats or semi-apo binocular ranges.


These binoculars have connectors which accept 1.25” eyepieces, so there's nothing standing in the way of using your own eyepieces. Due to the relatively short focal length of 560mm however, the magnification used is nt recommended to exceed 100X. The binoculars come with two pairs of eyepieces already included, allowing you to select between magnifications of 20X or 40X. The use of separate 1.25" eyepieces now also allows the observer to use nebula filters for observing DSOs.


These large binoculars let you to observe the night sky in particular comfort -  because using both eyes is less strenuous and much more fun. The large objective diameter makes a rich variety of objects visible. Objects appear differently compared to the view through a telescope, they seem three-dimensional. In addition, there are two 100mm apertures providing more light gathering capacity than the single aperture of a 100mm telescope, with which one observes monocularly anyway. Open clusters, extended emission nebulas and other DSOs can all be well seen.


Omegon Nightstar 20+40x100 Triplets are optically and mechanically outstandingly well-constructed binoculars.
