I think to buy cheap 10x50 binoculars for astronomy observations. My leaving area is light polluted, I can see only bright stars and planets in naked eye. Will I can with this binoculars observe Saturn rings, Jupiter moons, Uranus and Neptune planets? What deep space objects I can observe with this binoculars in light polluted area?
This is totally anecdotal, but based on my own observations with a pair of 10x50 binoculars on a light-polluted suburban street in South East England...
- Rings of Saturn: No
- Moons of Jupiter: Yes, all four main moons are easy to see (assuming they're not behind the planet at the time obviously!)
- Uranus and Neptune: No
- Deep sky objects: I have managed to observe the Andromeda galaxy as a very faint smudge, but that's about it.
Exciting things that I have been able to see include:
- Open star clusters, especially the Pleiades and the Praesepe (beehive) cluster. These are underwhelming or invisible to the naked eye, but I find them quite beautiful through the binoculars.
- Double stars e.g. Epsilon Lyrae.
- The moon, in much more detail than is possible with the naked eye.
This sounds rather negative, but I still think it's been well worth getting the binoculars. They're a great next step from naked eye observing, since they're easy to 'point and shoot' - no setup required like there is with a telescope. Plus they're easy to take with you if you're going somewhere with dark skies.
Ultimately if you really want to see those rings of Saturn, you're probably going to need a telescope. Perhaps there is an astronomy club nearby where you can try some out?
