Description

Assigned Ha, OIII and SII to Red, Blue and Green. Then used Ha as luminance. Very little OIII in this object.

IC63 is illuminated by the B0 IV star, Gamma Cas. IC63 can be referred to as a "cometary cloud" and is pointing toward Gamma Cas.

IC63 has bright filaments that are ionized fronts of gas created by Gamma Cas, and seen by us as nearly edge-on.

There is some discussion in professional circles as to whether the Ha signal we pick up is actual emission from the nebula or reflection of the Ha emitted from Gamma Cas that is scattered by the dust in IC63.

Multiwavelength spectroscopic analysis is the means to resolve this issue, and much of this lies in the realm of professional equipment and analysis.
