Sun mosaic from 2 images with Coronado SolarMaxx III

Dear Mr. Kloss,

Here's a first image with the SolarMaxx III, 70mm/400mm.

Camera: ASI 290 mini
Processing: Stacking: AS 3 with 1.5 drizzle,
Mosaic: 2 images, Microsoft ICE
Pixinsight: HDR, Curves, unsharp mask, curves again.

Now I'm looking for a faster camera; the ASI 290 mini with USB 2 only delivers 5 fps. Even so, without a Barlow lens, it's still very undersampled.

Best regards

Christian J.
