Description

This three panel solar mosaic spans the southern hemisphere with sunspots dotting the surface from limb to limb. The most prominent spots are seen at the center of the image with AR 12909, 12908, and 12907.

Each panel was processed using best 5% of 2000 frames and stacked in AS!3. Wavelets were applied with RegiStax. Panels were cropped slightly in Photoshop to trim stacking artifacts from the edges before being stitched together using the Photomerge automation tool. Further sharpening and noise reduction were applied using the Adobe Camera RAW filter. False color was then applied using a gradient map.

Seeing was relatively poor with mostly clear skies.
