Review on 🔭 Master the Skies with Celestron's 20x80 SkyMaster Pro Astronomy Binoculars by Paul Gravely

The pair originally ordered were collimated incorrectly. Celestron replaced them free of charge and checked the collimation (shipping included). The exchange lasts 5 weeks. Requires strong elbow brace to stabilize when hand held as they have high magnification. The mounting adapter works well with a tripod or dovetail adapters. Chromatic aberration is noticeable when viewed in high contrast daylight.
