Topic: Night sky image stacking

[sebeclake]

Here is Westford Weather's Vermont weathercam time-lapse from yesterday: http://www.westfordweather.net/yesterday.php

This made an interesting view of the night sky and stars using the sebectec image stacking feature that we have been working on.  At night there is a 20 image running stack with each frame having a 30 seconds exposure so what you see is equivalent to a 10 minute exposure with the Olympus SP-500UZ.  Each frame has a dark frame subtracted from it to reduce bad pixels and fixed pattern noise.  It switches back to auto exposure during the day.  The time-lapse is updated every day.  -Mike
