astroenthusiast 279 Posted April 18, 2021 The image of the Sun’s Chromosphere was taken on 04/11/2021 at 12:53 PM ET, using an Altair Hypercam 174M mono CMOS camera, fan cooled and a Daystar Quark Chromosphere H-Alpha filter. The image was over exposed to show the solar prominence to the lower right. Nasa data was analyzed to guestimate (visual) the Earth’s size in comparison to the prominence. Processing software used, AutoStakkert 2.6.8 (200 sub-frames), RegiStax 6.0, and Adobe photoshop. Nasa data: https://lnkd.in/djNtn-X (no copyright data was taken from Nasa). Link to comment
