The narrowband workflow I follow is uses either 1 to 3 narrowband filters
- HA: Hydrogen Alpha
- OIII: Oxygen-III
- SII: Sulphur-II
This is the most common type of imaging for those of us living in heavily light polluted locations due to the narrow window of light that these filters allow to pass. This narrow window helps reduce the impact that light pollution on the image as a majority of the pollution is filtered out.
The Reference Frames and Pre-Processing steps can either be done manually or with an automated process by leveraging the Weighted Batch Preprocessing Script
Note: I use this as my personal guidebook for image processing. There are so many things to learn along the way and placing them in a blog will help me remember how and why I do certain things.
