Description

This was taken with the Orion 8” Astrograph, the QHY 128C camera and the Paramount MyT mount doing 30 second exposures for a total of 1 hour and 45 minutes. It took 4 hours and 40 minutes just to stack ☠️

It was pretty difficult to process because I did not take flats and did not use an IR cut filter so the bright core yielded some pretty bad halo all around the center of the image. I just bought an IR cut filter so hopefully I don’t run into that problem again in the future.
