This is NGC 1499, aka the California Nebula in the constellation of Perseus. (Tilt your head to the right if this nebula doesn't resemble the State of California in the USA.) Unlike previous HαRGB composites, I did all the combining of the Hα and RGB in Photoshop. First, I used the Hα in “Linear Dodge” mode to pre-saturate the Red (33%) and Blue (3%) channels, and then used the Hα as Luminance at 50%. The result looked better than I could do with my own software in “trial and error” mode.
Mouse-over the image to see the Hα image in grayscale. Mouse-off to see the HαRGB composite. A higher-resolution image is also available. North is up.
