Giant sunspot AR3664

After last night's spectacular aurora I thought it appropriate to image giant sunspot group AR3664 as it starts to rotate out of view.

SkyWatcher 120mm f/8.3 refractor, APM Herschel wedge, ZWO ASI290MM camera, SkyWatcher EQ6R mount.

Best frames stacked with AutoStakkert, wavelets adjusted with Registax, other post-processing with Photoshop and PhotoScape X.
