Description

Over the years have imaged this a lot with various scopes but this is the first time with AI processing.  They estimate there are from 300,000 to a million stars here.  A lot of detail and stars, but, I am not getting the color I want. This is with the spectrophotometric correction, so maybe this is truer to life, but it is sometimes called the "Blue Snowball".  Without the correction is it much redder. 

This one here turned out well (IOTD in 2017) from another dark site using multiple exposure length and HDR processing to get the detail in the core.  Easier just to use AI?  You can tell the background did not have AI noise removal.

Here is what I got in light pollution from home in 2015 with my Tak 180ED.  Did not know much about processing then.
