Description

The nebula was images with Ha, SII, and OIII - the Hubble palate was used, SHO.    The Stars were imaged using 20 Red, 20 Green, and 20 Blue images each exposed for 8 seconds.   After the image as stretched - I removed the stars using "Star Exterminator"......I did the same thing with the RGB stars.   The last phase of processing was to add the RGB stars back to the fully processed image of the Nebula.

I have found that I have difficulty imaging in narrow band and keeping my stars from being over exposed - lacking color - and when guiding is pitiful, the stars are often bloated.  Using these short exposures helps to maintain color - keep the stars tight and sharp with no processing apart from color calibration and stretching.

I have done several youtube videos - linked below on this processing.
