The Planet Mars in Red-Green-Blue
I shot this from the Heavenly Backyard Garden using the Celestron 11" EdgeHD telescope with a 3x Barlow on the night of September 22. During a brief opening of the clouds, I was able to 'somewhat' get a picture of Mars but the atmospheric seeing was still rather poor but I was able to capture it using a monochrome camera (ZWO ASI 1600mm). I shot it with 3 different filters; Red, Green, and Blue. After compiling the color-filter frames, I merged them into an "RGB" image in Photoshop to generate this color photo. I included each of the B&W filter frames in this image to give you an idea of how this is done. Keep in mind, with all the moisture in the sky and with passing clouds, I couldn't achieve perfect focus, particularly in the blue light. I'll have to wait for a clear dry night for that. The reason for using a monochrome camera is that you can get a much better quality image versus a one-shot-color camera. Mars is now shining a fiery Ruddy red high in the eastern sky by 11 pm. It is shining brighter than Jupiter now and will be at its brightest on October 13.
