The BRESSER NightExplorer 7x50 astronomy binoculars are ideal for terrestrial observations in poor light conditions and discovering the night sky. They feature a 50-millimetre objective that lets in plenty of light. Thanks to the 7x magnification, objects that are 700 metres away appear to be just 100 metres in front of you. Compared with binoculars with a higher magnification, these binoculars allow you to see much more. At a distance of 1000 metres, the field of view is 126 metres wide. On clear nights, you can view large objects such as the Milky Way. During the day, you can explore fascinating landscapes until twilight.

You only need to adjust the focus if the next object is far away from the previous one. To view objects in the immediate vicinity, you can adjust the close focus from 8 metres.
