VDB 4- NGC 225
NGC 225 is an open cluster in the constellation Cassiopeia. One of its stars, the variable star V594 Cas, illuminates the blue reflection nebula vdB 4. There are an interesting number of what appears to be globular structures (fingers) in the field as well as some H alpha. All of this surrounded by dark nebulae.
Imaged in LRGB and H alpha at Dark Sky New Mexico, OTA Planewave CDK 17.

One of it's stars, the variable star V594 Cas, illuminates the blue reflection nebula van den Bergh (vdB) 4, which also cataloged as LBN 604. It seems, that vdB 4 is a remnant from the cloud that formed the cluster. Ha also shows an outflow associated with V594 Cassiopeiae.
Taken with a Planewave 17" f6.7 on a Planewave HD Mount and a SBIG 16803 camera. Imaged from "Dark Sky New Mexico" in Animas.
