Description

This is another long exposure image to look for faint dust/IFN. I like to call this NGC1184, but that was the tiny object in the middle that I could plate solve to, and the capture is of the Mandel Wilson Cow Nebula/MW 7. There appears to be some amount of dust in this area. Any comments/critiques would be well appreciated.

Lum: 24x10min
RGB: 12x5min each
7hrs 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.
