Hey all. New member.

Hi i'm a complete novice at astronomy but i finally managed to get myself a telescope and i hope to be able to use it well. It's not exactly a great telescope, (just a 70mm refractor), but i've managed to see quite a few things with it already. I thought i'd join this to get as much tips as i can so my telescope doesn't end up stuffed in the attic gathering dust =].

Welcome and I hope the last few clear days has given you something to look at such as Jupiter, Venus and the Moon.

Regards, David

A few nights ago i managed to see jupiter and the four galilean moons but i only managed to see the north and south equatorial belts and no 'big spot'. Not sure if that's because of my telescope or the light pollution.

Jupiter rotates and the Great Red Spot has to be near the centre of the visible disc.
So either it wasn't there or was not easy to see.
It should be visible in the 70mm refractor.
It is a long time since I used one, but maybe 100 times magnification will show it if the Seeing conditions are good.
Others can advise.
At least you saw the two equatotrial belts and moons.

Often if it is not visible one day it might be visible the next day as Jupiter rotates about 2.5 times in one Earth day.

Regards, David

If you are up late say after 2 a.m. have a look at Saturn.
That is wonderful if you have not seen it.

But maybe 3 or 4 a.m. is better as Saturn is higher. It will be easier in the next few months.

Ok thanks for the advice David. I'll try again when a night is clear. I haven't seen Saturn yet but i've always wanted to see it's rings. I don't mind staying up late so hopefully i'll find it soon.

Thanks again, Chris.

Hi Chris, Welcome!

If yo want to know the best times to look for the GRS there are a number of possibilities, for example:

use a planetarium program to show the night sky (Stellarium is very popular and is free to download), this will include informaton/ graphics showing the position of Jupiters moons and the GRS.

use a small program called The Planets (needs Java to run ) from http://www.cpac.org.uk/ , or go to Calsky.com for online predictions

go to Sky and Telescope and read data off this table (times are in GMT/UT)
http://www.skyandtelescope.com/skytel/b ... 58424.html

The table is probably the most straightforward option,

Hi Brian, thank you for the advice, the links should be extremely helpful. I should be able to spot it in no time. Thanks again.
