Description

3h20m (50x4min) - canon 50d @ iso1600 + astronomik CLS, and c8 with 0.63x reducer. effective focal length 1260mm; f/6.3

processed with pixinsight 1.7

i did better on the background noise reduction with help from the pixinsight forum. however, i did not mask the stars when i did the noise reduction and they got a little goofy. i'll probably wait to reprocess this until i can collect some more data.

the color balance is better here and i boosted the saturation a lot. i could have masked a little better for the faint areas so that the smoothing does not look as abrupt.
