WOW amazing animation. what do you use to process the images?

[GreatAttractor]

Stacking in AviStack 2, wavelet sharpening in Registax 6, levels in RawTherapee (operates on 16-bit images). Then I open all frames as layers in GIMP, align them by hand and export as animated GIF.

Magnificent pictures and absolutely stunning timelapse :) this is something I really want to do but the sun never stays out long enough. A very big well done, I love it

Thanks!

The Chameleon turned out to be the ultimate camera, but now I am beginning to see aperture limitations. I'd like to have the granule boundaries and filaments better-defined. I can also see from your otherwise perfect reference images out of the wedge that 140-150 mm just isn't sufficient for this. I'm thinking of moving to an 8" Newt.

Very nice animation, well done!

I put together a few raw videos - conditions were really good:

(for best viewing go directly to Vimeo and watch in HD)
