ASTRO: NGC 4449

NGC 4449 is a popular spring galaxy because of it's irregular structure. I
wanted to do an allnighter on it in April new moon time, but decided after a
bit more than two hours that I had enough signal and rather do some colour
frames instead of more luminance. Colour data is still waiting to be
processed.

Conditions were very good by city standards, especially the seeing was
amazingly good. Even the raw stacked images looked sharper than most of my
images after sharpening. Any fuzziness left comes from the very strong
logarithmic stretch I did to show the fainter parts better.

Taken from the middle of Berlin with an 8" SCT at f/6.5, G11 mount, SXV-H9
camera, 25x5 minutes.
