The Moon and stars with a DSLR, April 27

A tripod mounted Pentax K-x DSLR fitted with a 70mm lens was used to capture 9 x 30s RAW images of Casseopeia at ISO 12,800. The images were stacked in Deep Sky imager to produce the final image. Lines were animated into the image to show the main stars of the constellation:

At ISO 1600, using a 50mm lens, a 15 minute exposure of the sky around Polaris was made to produce star trails:

At ISO 400 and 1/500s, 16 exposures were made of the 88% waning, gibbous Moon and stacked as tiff files in Registax:
