Another basic question, how do you focus your camera for DSO?
Is it just by using short exposures and adjusting till everything seems sharp?
Is there a particular star or DSO that is commonly used to set the focus for infinite?
Thanks.  |
Bahtinov mask is your answer here. You can buy them or make them totally up to you but I and I'd say most people that don't have software doing it for them would swear by them. Basically you take photos of a bright star in the centre of your frame and the bahtinov mask creates defraction lines. When all the lines are evenly spaced, you're at infinite focus. It's dead easy and if you have live veiw you don't even have to take test shots, just zoom in to the star and adjust till the lines are right. Google it and you'll see what I'm talking about. Any bight star will do.
