Having made the effort to go out and actually do this, it seems to have really paid off.
This is Byron Bay's Lighthouse, NSW, Australia on about a 10 minute exposure, rubber bands are a man's best friend!
Wow! It only takes 10 minutes??? I have been wanting to know how to do this, because I love getting the stars and all at night... keep doing these, maybe for longer? I can't wait to try it now! I might go out tonight and try it after work!
Avoid star shooting when the moon is out, it may not look very bright when you look at it but over 10 minutes or more it begins to resemble the sun, and will almost certainly drown out the stars in it's own light. Bring a flashlight with you to focus on objects because it's a nightmare trying to get things in the forground in focus, on the other hand if you just want a full on landscape with mountains and stars in the distance set your camera to focus on infinity, sit back and enjoy.
You will have to adjust the camer's white balance too, most cameras aren't prepared for the temperature of the night.
Patience is your best friend because night photography is very time consuming.
