Mars and some late season gas giants, 8 Nov

The main focus of the night was Mars (again), but I also took a few late season happy snaps of the gas giants in the twilight. It took a while before the seeing improved to the level of the night before, but I got one good one away. This Mars was done a little differently, stacking only 1000 frames out of the 75000 taken, and I upped the gamma level to 1.2 to improve the appearance a bit.

Mars and Saturn shown at 150% captured size, Jupiter at captured size.

Great set of images, very nicely done, seeing must have been acceptable.

Very clean images Andrew. The gas giants are dimming now in mag and very nice Mars as it starts to turn its back on us. Interesting idea to do a minimal stack - it must be a high quality graph!

Good work

Thanks, yep the seeing was probably one of the best nights of the year

I usually try a fixed number of frames, using the smallest number I can get away with without increasing the noise levels. Usually 3000 frames (out 75000) is the minimum, even then the noise was minimal. So I tried 1000, 1500 and 2000 and even with 1000 frames the noise was very low so I processed further. Seems to have worked out OK here

Really nice collection Andrew. I like your Jupiter one. Fantastic details around the red spot.
