AstroPhotography The Canon G2 is not the ideal camera for taking astrophotos but I can still have some fun with it. The G2 can take exposures up to 15 seconds. Any exposure that is 1.3 seconds or longer has automatic noise reduction through subtraction of a 'dark frame'.The Moon and Jupiter were only three degrees apart on January 26, 2002. Ice crystals in high cirrus clouds caused the Moon and Jupiter to be surrounded by a halo.  On March 16, 2002 we had one of our regularly scheduled HAA observing sessions. The conditions that night were excellent. The first picture shows the sky that greeted the first of us to arrive. You can see Venus below and to the right of the moon but Mars is positioned above the frame.  The next image of comet Ikeya-Zhang is a 15 second, f/2.5 exposure at ISO 400 on a tripod.  The following image is also of Ikeya-Zhang. It is a 1 second hand held exposure at my 35mm panoptic eyepiece on my 20" Obsession telescope. There was no way I could focus but I'm still happy with the result. (Now I know I'm going to get an adapter to attach my camera to the scope!)  |
