With clouds and rain the predominant theme in the weather in UK recently, there has not been an opportunity to do anything more than surfing the net and doing processing with Pixinsight of the data that I’ve managed to capture up to now. I decided to process LBN581 captured in narrowband, which is my preferred imaging spectrum for wide-field images.
LBN581 (Cederblad 214) & LBN589 are emission nebulae in the constellation Cepheus. LBN581 is about 50.0 x 40.0 arcmin in size, while LBN589 is about 60.0 x 30.0arcmin. I had managed to capture at least 20 frames for each of the H-alpha, O-III and S-II channels, using Gain 200 3min subs. Captured with ASI178MM-cool, Samyang 135mm F2.0 wide open, with Astronomik 12nm narrowband filters (H-alpha, O-III and S-II).
The first image was processed in HOS Palette (Red = H-alpha, Green = O-III, Blue = S-II).
The second image was using the Hubble Palette (Red = S-II,Green = H-alpha, Blue = O-III).
I know I do prefer the Hubble Palette version to the HOS version, as the H-alpha has overpowered the image in the HOS version, which was to be expected.
