    Not sure whether your camera has the options to set the ISO manually. To get good clean shot, set to a lower ISO, and use a tripod to prevent blurring shots and get a longer exposure.

    how to avoid?
    there are programmes such as neatimage and noiseninja out there .... free for trial if i am not wrong...they should help to reduce noise on ya images...

    of coz if u didnt wanna do this the other obvious answer is to get a camera with better noise control then hahah

    cheers

    i think the best way to have low noise is to use long exposure,and u would need a tripod for that.for photoshop i think theres a plugin to clean up the noise but i cant recall the name..anyone knows the name?

    Wah.. what camera and what ISO did you use? Have you resized the picture or is that a 100% crop?

    Here is a night image shot at ISO800.


    And here is a 100% crop of the region with the moon. And excuse me for being blunt, I think the noise is still better than that of your image.

    thats one very noisy pic, what camera u using? the best option is to download a noise reducing program, or use a lower iso, or get a camera that can handle high iso with less visabble noise shown

    I heard if you cool your camera down you reduce the noise off the CCD. Less heat less noise. don't know how true this is.

    Yes.. Some astro people use thermo electric coolers to cool their CCD during the astro shots. One problem is condensation.

    Looks like taken with a pns due to the 3/4 ratio. Like mentioned, you might like to use a tripod and the lower iso for this type of shot.
