The Veil Nebula is an exciting part of what is found in Cygnus. It is a supernova remnant (meaning a star that exploded). I took a wideview (384mm) so what is called the Cygnus loop could be seen. The right hand side is the East Veil Nebula and the left hand side is the West Veil Nebula. These are often photographed individually.
The previous pic I completed was an SHO image using an OSC. This image was taken with a monochrome camera (2600MM). These 2 images that I joined show The difference between an SHO Hubble Pallet image and an HOO image taken with near natural colors. Showing both these pics demonstrates how creative images can turn out when you using false color (Hubble Pallet) and modified colors in a pic. This is only my second round at attempting these types of pics. I must say I am pleased with the different/creative displays in these images.
ASI2600MM Pro g100, AskarV@384f4.8 +darks/biases/flats, Ha 34 10min pics (5.7 hours exposure), O3 35 10min pics (5.7 hours exposure), S2 44 10min pics (7.2 hours exposure), RGB images were used to compose the stars, +darks/biases/flats taken over multiple nights 7/12/26-7/19/26.

To process the stars I combined RGB images. For the top image I combined the Ha, O3 & S2 into Hubble Pallet (SHO). The lower image is created by placing the Ha into the red channel and then the O3 data into both the green and blue channels (HOO). Exciting to see such unique colors!
