You would love to take beautiful, long exposures of the night sky, but even with a 24mm wide angle lens the stars start to streak with exposures longer than 20 seconds. And with a 300mm lens the stars start to steak after just 2 seconds. Not that long ago it would cost you well over $1,000 to buy the equipment that would follow the stars and allow you to take longer exposures.

That has all changed. An iOptron SkyTracker for under $300 will now do the job. This photo of the Orion Nebula was taken with a 300mm lens with an exposure time of 177 seconds. The night sky is now yours!
This series of articles will show you how to use the iOptron SkyTracker. The SkyTracker allows your camera and lens to follow the movement of the night sky, so you can take long photos without the star trails.
