Saturn 2019-09-23 19:00 UTC

It was clear tonight so I thought I would have another go at shooting a color Saturn - my last effort was too noisy for my liking and there was no surface detail on the planet. 

I shot at 480x480 10ms (100fps), doing 3 minutes Red, 3 minutes Green and 5 minutes Blue. Why more blue? In my limited experience it is much more blurry so I thought more time on blue would help. Also it looked like i could squeeze in 5 minutes before losing Saturn to the skyscraper due south of me. I only had time between twilight and the skyscraper for one set of subs, so this is probably the last Saturn this year for me. 

When I got in I realized I had left 2x2 software binning on, but maybe that was a happy accident as I wanted to minimize noise and the camera oversamples for my telescope anyway.

Shot with Skymax 102 and ASI178MM and manual filter wheel.

Nice image... some definite banding on the globe and even a greenish splodge at the north pole!

Thanks. I tried using smaller alignment points this time and I think it made a big improvement. I can't see a green splotch but I'll take your word 😃

Excellent effort, some nice details there especially for 102mm aperture.
