Thanks for the email responses for my last tutorial. I got a couple of questions about how do I manage to get sharp images at night of the stars. In this tutorial, I have listed the key elements you have to master when you want to capture most crisp images at night.
If you want the stars to be sharp and in focus, you need to learn how to focus to infinity. Every lens seems to have a slightly different spot when focusing to infinity or near to infinity. Try focusing in daylight and learn the infinity focus point of your lens.
- Capture daylight test images while using the widest possible aperture value
- Photograph a vast landscape or subject far away
- Use the live view mode zoomed to refine the focus in manual focusing mode
- Import the pictures to your computer to examine further
2. Camera Equipment
Use a wide-angle lens with a wide aperture to capture Milky Way and stars. If you are photographing on a windy night, get a decent tripod and use counter weight to keep the tripod steady. You can view my gear recommendations for star photography here: http://www.star-photography-tutorial.com/gear. Here is a quick list on what I recommend getting:
- Wide-angle lens: View my Nikkor 14-24 mm f/2.8 Review
- Light sensitive Camera (decent ISO performance) — I tend to use ISO settings up to 8000
- Steady Tripod — When you need to get that extra sharpness get a decent tripod
- Remote controller, or built-in camera timer — If you use the timer set it to five seconds so the camera has enough time to settle before it takes the photograph
