H-alpha Sun – September 23, 2016
Some good seeing today for these images.
AR 2596 (up in the images) looks very interesting with a whirlpool of plasma around it. AR 2593 has a plasma mountain next to it. Both promise a good show as they get closer to the solar limb.
Equipment: 150mm F/8 SkyWatcher achromat, UV/IR cut filter, Quark chromosphere, ASI 174MM. Best 700 out of 4000 frames. Seeing: 6/10.
And a slightly better shot of the same area, but a few moments later:
And a small active area with a nice filament:
Three different processing of the same filament from the above image:
And one last shot, showing the limb with some spicules and a prominence:
