Mars and Saturn Apr 15

There was some thin, high level cloud over Adelaide last night by the time Saturn rose out of the murk. But since the scope was already set up and cooled, I gave it a go anyway.

The reduced transparency kept me to 15 fps even on max gain, which meant shorter stacks and more noise than I would like, but the seeing was reasonable enough to get this result.

C11 + Orion LRGB filters + TV 2.5x Powermate + DMK21AU04.AS camera, 75% of 2400 frames stacked with AS!2.

The cloud got a bit thicker, and I was about to pack up, when on whim I thought I'd have a go at Mars with the old Neximage webcam. By now, Mars was well past transit, and with the haze things were far from ideal. I was surprised by the result.

C11 + Orion L filter + TV 3x Barlow + Neximage web cam. 50% of 3200 frames stacked with AS!2.
