[QUOTE="BF Hammer, post: 793783, member: 48483"] Here is my experience taking Milky Way photos. Go all manual mode. Manual focus, no auto-ISO, and manual exposure mode. ISO 1600 or 3200 is a pretty good first try at a location. Don't sweat the ISO noise, that should disappear if you do an exposure stack. And prepare to take a minimum of 60 shots, 100 shots even better. Focus by zooming in the liveview on the back of the camera on a single star, and adjust focus until it is at it's smallest. You are then at true infinity focus, you can now aim anywhere. Your exposure time is going to be limited by your focal length in order to prevent star trails. I had best luck at 15 seconds with 20mm, I was a bit too slow at 25" with a 15mm lens. 20 seconds would have worked there. Shoot wide open aperture, hopefully f/2.8 or less if you have it. I can't stress enough, more exposures you take to stack, the better the Milky Way detail. If you think 20-30 is going to be plenty, start looking at what the pros like Allyn Wallace are doing. Couple of other pointers: October is past the peak Milky Way core season, best months in the north are June-July, even though there is less night. The B4 setting is about autofocus behavior so should not be stopping photos when in manual focus mode. [/QUOTE]
