Description

An explicit rendering of halos produced by the QHY168c camera and some wild ghosts in the RASA by Orion Belt Stars. As a test the flat clear Rowe corrector filter glass was removed. This was to test out the hypothesis that the clear glass contributed to the halo effect. Removing the glass doesn't seem to make much difference.

Colorful though...
