Although I have taken a few shots of the moon in the past this is the first time i have actively tried shooting stars (not the TV show or like Mark Chapman). I set up my tripod and took both my 18-55 mm lens and my 55-300 mm Tele lens. Usually when shooting the moon i would use a medium fstop and a fast shutter speed and my tele lens and as the moon kicks out quite allot of light I would say its easier but with the stars due to the fact they are far far away and don't emit as much light its not as easy.
The higher the ISO the more image noise gets captured so its a case of finding a part of the sky that's not covered in clouds and playing about either until you get it right or you get cold. Also the longer you leave the shutter open the more distortion you get due to the rotation of the earth.
I used a IPhone app called Star Walk (about £1.79) to find Orion and captured the below -- please note you may need to click and enlarge it!
F3.5 - 2 .50 Sec Shutter - ISO800 18-55mm @ 18mm
Also a handy couple of tricks I learned was using a tungsten white balance to bring out background stars and also editing the RAW image in PS and zooming in and cropping cant wait for the next clear night
