Hello all, I am vacationing at a place and noticed that the night sky has more stars that I have ever seen in my life. I tried reading up on how to take night sky pictures and still it came out terri ble all blurry .. please advice. I am hoping to get a few good shots of the night sky before I leave.
I would not trust the focus mark but rather use the live view and zoom in to manually set your focus. You should be able to find a star that is bright enough to use. Then drop out of live view and take your image.
Also try some longer lower ISO shots with noise reduction turned off. It may make some of the small stars 'go away'. If the star trails get too long or are distracting try a shorter shutter speed to find a good balance. You will have the shortest star trails if you aim toward the polar region.
Shoot in RAW to adjust your white balance after the fact if the auto setting is not turning out well.
I would have to jump in and agree about the focus being off. I have a handful of lenses that I trust the infinity mark, but they are all my older manual focus primes. The high ISO performance of the D7000 makes it a great camera for capturing those stars.
