The Sun in 2026

| Pete Hill took advantage of the clear skies on the 7th April 2026 to capture the following five images of the Sun. All images were captured using a DMK 41 mono camera, and in each case 1000 frames of video were stacked in Autostakkert3, and wavelets processed in Registax 6. All final processing, alignment, and colouration was done in Photoshop CS6. All used an HEQ5 pro mount tracking at solar rate. The first image is an H-Alpha view taken with a Coronado PST piggy backed on a Skywatcher 102 telescope. Next is a Calcium K image taken through a Baader CaK filter using a 0.5x focal reducer, viewing through a Herschel wedge attached to the Skywatcher 102. Following that is a visible light image taken using the same setup as the Calcium K image, but using a Baader Continuum filter instead. Finally the image of sunspots was taken using the same setup as the visible image but replacing the focal reducer with a Barlow lens. Images Credit: Pete Hill. |
