yesterday i did see Saturn by my 70mm (2.8") Altazimuth Refractor telescope, but what planets else i can see?

Question

i used 9 mm eyepiece attached to a 2x Barlow lens.

Answer 1

Mercury and Venus will show phases, like the Moon, but not much else. Mars may show the polar ice cap, but your telescope is too small for much else. Jupiter will show 4 moons and belts in the atmosphere of the planet. Uranus might show a very small blue-green disk at high power, but Neptune will just look like a star in your small telescope.

Venus is the very bright star you can see in the west at sunset now. You can also see Jupiter if you stay up really late, but it will rise earlier later this year. While you will be able to see Uranus and Neptune, your telescope to too small to make those worth looking at, and since they cannot be seen at all without a telescope, you may find it hard to locate them! Mars will probably disappoint you, but give it a try at the next opposition anyway. Mercury is tough because it is never far from the Sun. You have to catch it just after sunset or just before sunrise, and then it is very low on the horizon. I have only seen it a couple times myself. The planets are always moving, so you need some tool to tell you where they are. Try the source.

Answer 2

Do you mean which are the planets you can see?
We can see some planets with our naked eye, these are Mercury, Venus, Mars and Jupiter, apart from Saturn. While Uanus and Neptune can be seen through a telescope and also the dwarf planet Pluto.

Answer 3

Jupiter, Mars and Venus should be easy with that size scope.
