Here's another narrowband hydrogen image obtained with my imaging
rig consisting of an SVQ100APO refractor manufactured by
StellarVue, a ZWO183MM PRO imaging camera, and AstroDon
TruBalance H-alpha filter with a 5nm bandpass. Each image
is a 5 minute exposure, with enough frames collected to achieve
a total exposure time of about 11 hours. Processed in PixInsight.

This region of hydrogen gas is cataloged as IC63, otherwise
nicknamed the Ghost of Cassiopeia. The bright star is gamma
Cassiopeiae, which is the middle star in the 'W' pattern
forming the constellation.
