Lobster Claw Nebula in Cassiopeia, 11000ly, NGC7510 cluster upper left SHO

This is the second image taken with my new Askar 120APO that has a focal length of 840mm as well as a 120mm objective lens, much bigger than my Askar V at 80mm.

The original stacked images for everything did not give me a hint of how colorful and alive the SHO image would be. The yellowish parts are Ha the redish parts are SII and the blue parts are OIII. Using a mono camera really does create possibilities that are not present with OSC cameras.

I developed RGB, HOO & SHO images for this image. The SHO image was by far the most interesting and colorful.
