He's with us again! Favorite binoculars of astronomical observers!
Do you remember your first moments with binoculars under the starry sky? Hundreds of enthusiasts associate them with our Delta Optical SkyGuide 15x70 binoculars . Its affordable price and sensational optics have become a legend. SkyGuide binoculars magnify the image by 15x, and thanks to the lenses with a diameter of 70 mm it achieves a very good stellar range.
The lenses were covered with multilayer antireflection FMC coatings on all active optical surfaces. Correct correction of chromatic aberration and a comfortable, large field of view of 4.4 ° at 15x magnification were also taken care of. Large prisms made of BaK4 glass are standard in the SkyGuide series binoculars .
In addition to good quality optics, the mechanical solutions used deserve attention. The entire body of the binoculars, including the tubes in which the lenses are mounted, is made of metal and covered with rubber. This advantageous solution is very rarely used in this price class. The focus is adjusted individually for each eyepiece - there are no mechanical problems with play on the ocular bridge. Thanks to this, the binoculars will work well for many years.
The binoculars come complete with a durable case for storing and transporting the device.
