These are serious astronomy binoculars. They gather three times as much light as a 10x50 mm pair, bridging the gap between binoculars and telescopes.
You really need a tripod for these binoculars. A tripod adapter is built into the binoculars but the tripod itself is a separate purchase.
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, you can see craters and mountains.
Venus is a small disk but you can see the phases very clearly.
Mars is a tiny disk.
Jupiter is a small disk. You can’t really see the weather bands but you can easily see the four Galilean moons.
Saturn is a very small elongated disk. If you have good eyes you may be able to see the rings but only just.
Deep sky objects (nebulae etc) are visible but faint. Some star clusters such as the Jewel Box look nice.
Comets can look great but they vary a lot.
