All began when one offers me an astronomical telescope for christmas. Then, I began to take interest in observing the sky and constellations. Later, I tried to observe them with some other instruments, beginning with binoculars.

later, I bought a telescope (Newton 115/900), in order to devote myself to my favorite occupation and discover the planets in the solar system. Don't you think that the sky which offers to us every night is really splendid ? (when it is not raining indeed !). Try and imagine the infinity of the universe in which you live ! It is absolutely huge ! Think that the nearest star is located at 40 thousand billion of kilometers ! We have good reasons to feel us very little, isn't it ?

I will use this page to give you some pieces of advices concerning observation, in order that everybody could enjoy with this natural beauty.
First, it is very convenient to have a pure black night, in order to distinguish even the less luminous stars. This implies that you should observe from the country, at a distance greater than 100 km of a city (the lights of the city will disturb you elseif). Winter is the best season to observe. That's right that the weather is cold, but the sky is then very black and pure. Moreover, the most beautiful celestial objects are visible in winter...

You could also observe in spring or autumn, but later in the night (after midnight), but avoid summer, because during this season, some residual light from the sun keep the sky illuminated (that is because the sun doesn't go very far under the horizon line). But if you are not very demanding, you can of course observe outer of these periods ; We can also see some very beautiful things !

Moreover, I will add that to see the objects well, not the magnifying of the optical instrument is important, but its aperture. Indeed, when you observe for example the Moon, whith a magnifying of 500x, you can see quite nothing through the instrument because of the absorption of the lenses. Moreover, the adjustments are very hard, and the system is very dependent of vibrations !

Concerning telescopes (if you've got one, even a littke one), I advocate rather an equatorial mounting than an azimutal one, because it is easier to follow a star during observation (I remember you that the movement of the stars is due to the rotation of Earth !), if you have early correctly installed your material. And if you want later make some photographs, this type of mounting is quite indispensable if you don't want to use a computer to guide the azimutal mounting... You will be able soon to go and see my page about my telescope, and see what I have and which accessories I've got.

Here are some photographs I've taken by myself with my telescope :
