The Clear Sky Sessions
Astrophoto M39 Clear Skies 23+24.
I shot several photos, more than i remembered, from M39 on two of those evenings in october when i tried to configure the flattener.
Here the high resolution astrophoto on Flickr:
What i learned is, that my next refractor will be a flat field refractor!
even if the final astrophoto looks somewhat nice. A closer look to a single exposure shows that i did not yet found the best distance between flattener and sensor. Especially with a look into the corners:
