This is data from my first light of my Aspen CG16M camera from about 4 years ago. It has been quite a learning curve to get my methods and processes down, but I think I am almost happy with it. I still do not have colour figured out all that well, so any comments/critiques would be well appreciated. My flats were off with this, and I now usually acquire much longer luminance data as the underlying luminance data are quite noisy.

Lum: 12x10min
RGB: 12x5min each
5hrs total

Data were acquired at my parent's cottage in a (grey Bortle 2) in cottage country, Ontario.

The final images are more of an experiment in presenting the low-level dusty parts of the universe. I wrote an algorithm in Python to eliminate the smaller stars, trying to minimize distortion as much as possible. I am still tweaking the algorithm, but may upload it to GitHub once I am happier with it. Any comments on the star reduction would be much appreciated as well.

This image is star eliminated with my own python star elimination algorithm and then the stars are slightly reduced with Pixinsight to reduce how bright they appear with 10min subs.
