This SHO image also includes RGB data for the star color.  A total of 41 hours of narrowband data and 6 hours of RGB data. Processed in PixInsight.

This is an amazing image! Were you there or was it a remote acquisition?

Michael, 

 

Thanks. I do remote acquisition.  I'm renting a pier in an observatory in southern New Mexico.

Excellent image Brian! I always like natural star color in any image! You have gone the extra mile by adding them to this narrowband image!
