Ghostly face nebula (Sh2-173) - Happy Halloween!

[x6gas]

I was imaging Sh2-173 in Cassiopeia the other evening.  Don't really have enough data but just for fun I thought I'd post this as it's Halloween and if I squint I can sort of see a ghostly face in here.

I've cheated somewhat: Sh2-173 is an Ha emission nebula but this is what I get when adding the monochrome Ha stack as a luminance layer.

For the record:

Kit: Mount: CEM40; Camera: Atik 460ex; Filters: Atik EFW2 with unmounted Astrodons (Ha 5nm); Guiding: Atik OAG, QHY 5II

Data Ha: 14 x 900s; RGB: 12 x 180s of each channel

Cheers, Ian

Yes that does look very ghostly.  Well done.

Some-one on Astrobin has called it the Phantom of the Opera Nebula.

Ah yes Carole you are indeed correct!  It seems that some do refer to this as the Phantom of the Opera Nebula - didn't know that so thanks for the info.
