NGC225 is cataloged as an open cluster and it has an associated dark nebula (VdB4). I imaged this right before AIC and just finished it up. The bright blue stars seem to spotlight the scene and the reflection components really do an interesting color mix of the nebula. The structures remind me a bit of an old lava lamp.
