“10x50” is a common size for binoculars, providing a good compromise between magnification and field of view. This is useful for learning the night sky, as well as being perfect for ground-based objects and scenery. You can use them with or without a tripod.
These binoculars come with a free 24-page booklet "Stargazing with Binoculars" written by our own "Space Dave" (Dave Owen). This booklet tells you everything you need to get started.
What you can see
The Moon looks nice enough without being spectacular.
Venus is a tiny disk. You may be able to see phases but it’s difficult.
Mars is a tiny disk -- it just looks like a bright star.
Jupiter is a very small disk. You can’t see weather bands but you should be able to see three or four of its moons.
Saturn is a tiny disk with a barely-discernible elongation. You can’t see the rings.
Deep sky objects (nebulae etc) are barely visible - faint fuzzy spots at best. Some star clusters such as the Jewel Box look nice enough. These binoculars have a very large field of view and are great for providing wider context for star clusters, comets and constellations.
