Digital camera hacks

[XabbaRus]

I have this theory that the spirits move really slowly so if I have it on a really long exposure I will capture them as they move across the lense.

Nah really, I'm photographing the night sky.

I use my dad's Nikon D90 for through the scope work, but for wide field stuff I want to use my camera.

A good slr camera with very high speed film and a wide open aperature is the weapon of choice here.

Most pepole using cams for astronomical purposes are using CCD cameras. There getting cheaper and cheaper. Orion has one that simply slips into the eyepiece and hooks up to a computer to display.

The other trick they do is to take multiple images, sometimes hundreds of images and 'stack' them using computer software which removes errors and ehnances 'good' data compiling all the images into a single image.

Here is the defacto authority on the subject !
