Saturn & Moons - LRGB+IR F30&F50 - 2 Oct 2022


MarsG76

I imaged this scene with my C8 SCT using a number of exposures, cameras and focal lengths during a night when it was a particularly clear and still night which delivered views in the eyepiece that were sharp as a tack all the way up to 406X magnification... I could not let such a clear night go by without imaging and so I decided to push the telescope magnification as far as I could.


I imaged this image using my Skyris 618C at f30, and through my DMK21au618 at both f30 and f50, 10 videos 90 seconds long at 60fps (f30)/30fps (f50) by using my 3X barlow and 5X powermates.
I also captured 10 videos through my IRPass685 filter at f30, although the signal was quite dim and the most I could run the capture at was 15fps for 2 minutes per video at maximum gain. The moons were imaged at f10, 15 fps also max gain.

I processed all data separately, than scaled down the f50 image to the f30 size and "screen" combined those two images aligned images together, this has revealed a little bit more detail within Saturn that was visible individually. I used this as luminance with the Skyris 618C stack as the color data, effectively creating a LRGB image.
I combined this image with the scaled up wider moon processed stack.
