Star-trail photography

I have always wanted to star-trail photography, but not for once the time or the place has been right. Last year in August it was. It may seem like a harmless photography, as you just have to set your camera on a sturdy tripod, find a nice frame to shoot continuously after every 30 seconds and then stack them together on Photoshop. 

In town it is hard to find an interesting spot where to point your lens, considering that it has to face the North Star, also it is hard to make your camera to shoot after 30 second for hours, as the button may give up sooner or later the pressure given to it. Last, but not the least the condense that will happen on your lens - the worst problem. 

I can only provide the link I followed to create this, not so wonderful first real star-trail in my life: http://petapixel.com/2013/03/18/how-to-photograph-star-trails-from-start-to-finish/

The rest is up to you.

Good luck!
