Week 16 - Moon & Stars














































Orion
===================================================================
I worked on the topic moon & stars. First I thought to make an image of the milky way, but this was not possible, because of the high light emission around here. So the next point to think about was: Will I capture the stars for a long time (2 hours) to see the stars as circle lines or will I freeze them in their position. I made some images with the second option. Settings are following:  Manual focus on endless.  F-Value 2.8f, ISO 800 and exposure time between 4-16 sec. A rule is the wider the lenses the longer you can exposure. If you want to exposure longer than 30 sec you need a tripod with a continuously update of the earth rotation and this is very expensive. For the published image I reduced the noise and increased the saturation a little bit. The gradient in the image is the light emission of the subburb.
