Description

A little over 12 hours total exposure time from my backyard, I tried a new noise reduction script called NoiseXTerminator. It worked better than I could have imagined. I applied the script in the linear stage of the RGB and Lum data, and stretched the data manually with STF and Histogram Transformation. The script essentially eliminated all noise without impacting the small details in the galaxy and stars. I highly recommend the script to anyone struggling with noise reduction, its worth the cost.

I had more lum data, but only stacked what I thought to be acceptable from average seeing. I had a string of 4 nights of imaging with little to no clouds with a new moon... pretty awesome!
