Description

This is the first time I used the 68III flattener with my William Optics FLT132.  I may still need to tweak some parameters in the system, especially with the autofocus. The first night there was some serious airglow in the night sky, which may have contributed to the bloated stars as well. The image was processed using Ha as red, OIII as blue, and a 7:3 ratio of combined OIII and Ha as green. The data between the two filters are imbalanced, I plan to add a bit more H alpha in the future to bring out more details of the outer rim of the nebula.
