Is there a way I can use my 20D to do some Astrophotography?
Each time I try to use the camera outside during night the shutter stays open for very long time, I am wondering if I have a setting set incorrectly?

Thank you

im assuming its staying open for soo long as its dark outside.

ive not done Astrophotography before but, my guess is because its dark.

for the moon id say get tripod, zoom in as far as possible and have a long exposure.

Hi, I recently posted a pic that I took of the moon with 20D. You can view it at Critiques and Techniques,under Partial Moon. The settings were ;

style="BACKGROUND-COLOR: #000000"shutter speed: 1/60

style="BACKGROUND-COLOR: #000000"Aperture: 5.6

style="BACKGROUND-COLOR: #000000"ISO: 400

style="BACKGROUND-COLOR: #000000"Auto Mode

style="BACKGROUND-COLOR: #000000"Tripod should be used.

style="BACKGROUND-COLOR: #000000"The purists will probably tell you these settings are no good,but I had some success with them.Good luck.

longer exposures for fireworks, for the trailing effect..



For moon shots, I would assume fairly short exposures.. They do not need to be long, since the moon is fairly bright and a close object. Now, for DSO's (Deep Space Objects) you'll need longer exposures to capture in more light.

FULL MOON: 1/iso @ f11

FIREWORKS: iso 100, f11-16, shutter open for 3-6 seconds at a time to catch burst(s)

ASTRO: STURDY TRIPOD and FULL MANUAL OPERATION
