The Clear Sky Evening
Bode’s Galaxy and Cigar Galaxy
Astrophoto M81 Bode’s Galaxy – M82 Cigar Galaxy – Clear Sky 13.
These two galaxies were more or less a technical test on an evening with light foggy clouds. Sky was clear for about 30 minutes and i was able to complete my tests and shoot this photo.
Here the result of 30 Minutes with dithering in the high resolution version on Flickr:
Lessons Learned
Since my CANON M100 is not supported on Windows Systems when it comes to astro-control-software, i switched to a Linux System using INDI and EKOS. The primary technical test was trying to dither and it was a real milestone for me.
