On sixth and ninth of march I have tried some new experiments with startrails. I made three pictures at the same place and the same sky. In this area of sky there is orion in the centre. The wide angel also shows taurus and beyond.
For generating the exposure I used the great free software SM-Thether to control the exposure from my PC.
The first picture is 27min (54 x 30s), the second 57min (106 x 30s) and the third is 22,5min (90 x 15s).
This short times combined with higher ISO800 made it possible to create timelapse movies from the last pictures:
I hope you enjoy it.
