Dark Sky Geek | The Bubble Nebula Project - Part III - Post-Processing in PixInsight @darkskygeek | Uploaded November 2022 | Updated October 2024, 4 hours ago.
This is the third episode of a four-part video series in which I take you, the viewer, through the entire journey of creating a beautiful deep sky image of the Bubble Nebula (NGC 7635), from the data acquisition to the image pre-processing and finally the post-processing. In this video, we post-process the nebula, using PixInsight. Fasten your seat belt, let's go!

In the previous video, I did an unboxing and shared my first impressions. In this video, I go over the results of a series of quantitative and qualitative optical tests I ran on this telescope and its reducer.
