vdB 4 and ngc225 - nebulosity and Open Cluster in Cassiopeia - L+HaRGB

LBN 534 LRGB

The above image is L+RGB done in Photoshop

ngc 225: From Wikipedia: "NGC 225 is an open cluster in the constellation Cassiopeia. It is located roughly 2,200 light-years from Earth. It is about 100 to 150 million years old."
vdB 4 aka Vandenberg 4, from Irida-Observatory.Org :"VdB 4 is a reflection nebula in the constellation Cassiopeia. It is associated with the very young open star cluster NGC 225. The cluster was discovered by Caroline Herschel in 1783. VdB 4 is centered on the variable star V594 Cas. There is some confusion about the bright nebula LBN 604. Most probably LDN 604 refers to the brightest part of VdB 4.

Session orchestrated by CCD-Commander
Calibration and processing of the RGB and Luminance in PixInsight as follows:
RGB: SPCC, BlurX, NoiseX, Gradient, Curves, HistogramTransform
Luminance: BlurX, NoiseX, StarX, Curves and HT and LHE
H-Alpha: BlurX, NoiseX, StarX, Curves and HT, HDRMMT and LHE

Photoshop processing:
RGB split into channels and the H-Alpha added to the Red and Blue using Lighten mode at 100% and 15% respectively
Starless Luminance layered onto the RGB using Screen blend mode.
Tweaks and small noise reduction then Save-for-Web
