Course on DSRL astrophotography

Back at home, after a weekend at Hauho. There we spent a nice weekend, with other enthusiastic colleagues.

Some info sessions were held on image processing technology. One session that was most most important for me, was held by Petri Kehusmaa. Also other items were covered, like stacking of the images and softaware details - with AviStack, RegiStax and IRIS.

I enjoyed of being there, and got many new ideas and tricks to use in my own astronomy hobby. Thanks for the organisers, lecturers and colleagues for the good weekend.

PS:
The collimation result is not the most important thing, it's the high quality time spent doing that on a good company :-)
