Description

This epic data collection was part of the set up of the Astro-Tech RC 10 in my observatory with Rob (Pfile). M57 was the collimation target. I appreciate all the help we have had from many consultants.

Processing was standard PI with HA mapped to R and O-III to both G and B as per Rick S's suggestions. HA and O-III were de-starred with Straton and the stars added back in from RGB. Rick also instructed on using the PI ColorMask Script to tone down the Cyan from the large O-III signal.
