DSLR astrophotographers must strike a delicate balance between ISO sensitivity, aperture, focal length, and exposure time every time they take a shot. The greatest single factor influencing all of these variables is the rotation of the earth. The iOptron SkyTracker attempts to relax these variables by cancelling out Earth’s rotation. Is it worth the price?
The Earth is constantly in motion, rotating once every 24 hours and taking a lap around the sun once a year. If you want to take great pictures of the night sky, it isn’t enough to know just what you want to shoot, but when. An astronomy simulation app can make planning your next successful imaging session much simpler. SkySafari 5 Pro is one such astronomy simulation app. Can it get the job done?
