This shot was taken some time ago with the 300d sitting atop of the 150ar traking as best it could for 10 minutes I recall. I wanted to see how much the foto would break down because of the long exposure. You can see on the right the degrading. In the foto we have the MIlky Way and both the clouds. It was a Moonless night and very clear.

Nice shot. Alex have you tried taking a dark shot and subtracting it to get rid of the amp glow?

Its not hard Alex. Take a shot of the same length of time but with the lens cap on. Copy that image and paste it over the first in photoshop. Then in blending options select difference and then flatten in the layers menu. Done.

There are other ways of doing it, but I find that a very good option for a quick fix. Before you flatten check to make sure the whole image has the hot pixels removed (covered), if not use the move tool or transform rotate to line them up.

Very nice Alex.

One point to remember that I fogot to mention. Do your dark subtraction before you do anyother sort of processing. Once you get the hang of it it takes about 10 seconds. I'm starting to save up my darks in a folder with very descriptive names for each dark so now when I need them they are really obvious. eg. ISO400 240sec 25 degrees. If you do this, start with the ISO number rather than the number of sec, makes it easier to find the one you want.

Mike there is 200 acres here (there) one human and 3 dogs. If you (other members) ever want to camp that would be fine, but its not clear and dark all the time ..just like everywhere else.
