Best 150 frames of video stacked with AutoStakkert, wavelets adjusted with Registax, false color and tweaks to contrast and levels with Photoshop.

Image Details:

I imaged huge sunspot group AR3038 through a brief sucker hole in the clouds. AR3038 has doubled in size over the last 24 hours. It is now several times the size of the Earth!
