Sigma 4.5mm f/2.8 EX DC HSM Pentax K Photo #34 Stars and Moon

21/01/2011 Star trails and moon over Monavale Beach. This image is composed of 7 stacked images of varying exposure. I used a Sigma 4.5mm fisheye lens. The len system gives a 180 degree field of view within the circular area. I then pointed the camera straight up. Image details 7 stacked images 10sec, 13sec, 15sec, 20sec, 25sec, 30sec, 30sec All stacked/layered in photoshop. I manually stacked or layered each image on top of each other one at a time blending each one 50% finishing with the last 30sec exposure. This gave the image a nice crisp look. I tried a straight up stack in photoshop but this image looks more natural.
