Sterennow (stars). The Milky Way above Greenburrow engine house at Ding Dong Mine, Cornwall. This a composite of a foreground shot illuminated by moonlight and a single 4 minute exposure of the night sky. Uniquely the Astrotracer function of the Pentax K1 allows for such a long exposure in a single shot at a relatively low ISO of 800 which gives sharp details of the stars without the noise present using other cameras with a much higher ISO



I also shot the night sky without the astrotracer using ISO3200 and a 30 second exposure. An extract of this is shown below, along with an extract from the 4 minute astrotracer shot. The 30 second shot is a lot fuzzier, noisier and shows less stars than the astrotracer shot. The stars do appear bigger in the 30 second shot, presumably due to star trailing. The 4 minute exposure was also taken using a super sharp Pentax 15-30mm lens and the 30 second exposure with a Samyang 14mm lens

The combination of image quality and subject matter make me feel small and insignificant! The first image is beautiful, the second pair reveals how sharp the Pentax 15-30 lens and astrotracer combination is and they all tell us you are a most accomplished night sky photographer!

Excellent! Amazing to think each and every one of those white dots is a sun line ours.

What a beautie!. Had to look up Ding Dong Mine. Surprised I had never heard of it as I have been down that area many times. Well done, I must have a crack at astrotracer.

You've really given us something to aspire to. Superb shot.
Both the *istDS and the K5 are incurably addicted to old glass
