New Rosette nebula with HA
I was able to get some hydrogen alpha data on the Rosette Nebula in between storms. I haven't been able to get much data lately because of all the storms. February and March were both socked in. It seemed that winter came late this year. April has been very stormy so far too. It hasn't all been bad though because I have been improving my post processing skills. One thing I have learned that has helped get better color balance is using the background neutralization and color calibration processes. This has helped my star colors and colors in my deep space objects. I apply this very early in post processing right after a do a background extraction. When adding HA data to a RGB picture, Pixinsight has a great way of combining these without wrecking the star color or object color and truly enhancing the detail in the object. In the earlier Rosette Nebula that posted in January, a lot of the stars appeared red. I didn't think this was a true representation of the star colors in this area. After I learned about the background neutralization I discovered that the red stars were from the red dominant color in the object. This new picture of the Rosette is a much better representation of the star color and vivid red colors in the Rosette Nebula. This is about 1.5 hours of HA data collected or 10 subframes of 8 minuets each integrated and noise reduced in Pixinsight.
