Mars and Saturn, 26th July (and animation)
I managed to just about win the battle with the clouds last night and sneak the first decent images of Mars and Saturn for a wee while. Both are showing distinctly more phase now (Sun off to the right), and Mars is a lot smaller now. There's some volcanoes, with Olympus Mons rising (the animation is two frames over 1hr 20min) and the dark spot at the centre is Ascraeus Mons, one of the row of three big Tharsis volcanoes. Vallis Marineris is at the lower right, above the bright south polar region. Not many clouds on Mars beyond the bluish north polar hood.
Saturn's not showing a huge number of features, but the shadow of the planet on the rings is growing more prominent, giving it a nice '3D' appearance.
Stacks of the best 4000 of 15,000 frames, ASI185MC, 200mm f/5 Newtonian barlowed to f/30. Stacked and processed in PIPP and Registax.
