Kata-Tjuta by night by godintraining Kata-Tjuta by night by godintraining
from the same series of [link]

I enjoy astronomical photography because it's a totally different technique and philosophy, and the result is always incredible.
Few tricks for you:
- when you take a long exposure picture of the stars always point the north in the northern hemisphere and south in the southern hemisphere. The movement of the stars is slower on the earth's axis, and you can avoid that the stars appear too blurred
- The auto focus of your camera will not work properly. A good tip is to setup your auto focus only on the central dot, and then point the moon. After, without move the focal point switch on manual focus, and you are ready to take pictures of the stars.
- Always start with a 30 secs and use a fast lens and a good tripod. If the photo is over exposed you can always reduce the time. If you take a photo of the moon you need a really fast shot (less then 1/3 of second), don't forget that the moon reflect the light of the sun
- The sensor of your digital camera generate more noise if the temperature is high. A freezing night on a mountain or in the desert is what you need for your masterpiece

When you'll watch your photos you'll see that the stars have different colors. The blue stars are young, the yellow stars (like the sun) are middle aged, and the reddish stars are going to die soon.

Enjoy

nice tricks. Didn't know about the sensor generating more noise when it's hot. That explains a lot :D

Yea, no worries! This photo was taken with 30 degrees!! A cold weather can help, but it's not the main factor ;)

Great shot, and advice.... I've been trying to take pictures of the moon for a while but I think now my camera is not good enough to do so... I don't think it has the right settings..... :( oh well....maybe someday I will be able to take such a beautiful picture. :)

Well sorta... There are random white stars that happen to be white dwarfs (the most common type of star in our galaxy).
