Description

Processed as HOO and as SHO.  The HOO was more to my liking, but when I added the S2 data with Pixelmath a little more detail was apparent, and I got the satisfaction of incorporating the S2 data.

Sh2-173 is an emission nebula lying 8,800 light-years from Earth in the constellation Cassiopeia. It is part of the Perseus arm of our Milky Way Galaxy. Its shape and dark dust clouds bear a resemblance to the mask worn by the Phantom of the Opera in the Broadway musical or the film starring Lon Chaney. Hence it is commonly referred to as the Phantom of the Opera Nebula. It is an extremely faint nebula requiring long exposures.    (Wikipedia)
