Description

Emission nebula Sh2-112 in SHO. I originally planned an HOO version but added Sii on the last night.

Imaged with CDK14 and ASI6200mm over four nights. The nebula is bright enough that I used only 5 minute narrowband exposures. The signal is good with all three of the SHO filters. The original color mix was with APP Hubble 3. One thing I like about that mix is that it produces decent star color and subtle nebula color. The stars are from the APP color mix without any adjustment. I  boosted the red and blues in the starless nebula with PI and PS.

Since this nebula doesn't have a common name, I call this the Blue Hole.
