Description

During Solar Minimum the sun can appear spotless for many days at a time, but there is still exciting features to observe by utilizing narrowband filters to isolate and highlight different wavelength dependent features.

This image highlight the solar granulation visible on & just barely above the photosphere of the sun.

I shot 3,000 serial frames in 15 seconds, stacked the best 20%, sharpened using Registax wavelets I designed and finally processed and colorized the image in Adobe Photoshop.
