Recommended Comments

The Sun’s surface in Calcium light (half disk) was captured using an Altair Hypercam 174m monochrome camera, fan cooled and Daystar Quark Calcium H-line filter with a built-in telecentric Barlow.

The second image (right) of the Sun’s Chromosphere was captured using the same camera equipment above, but in addition a Daystar Quark Chromosphere Hydrogen-Alpha filter with an internal telecentric Barlow at 0.5 Angstrom bandwidth was used.

A Televue 2.5x Powermate & SharpCap was used to magnify and stretch the image. The telescope used, a Lunt 80MT APO refractor.

Solar processing software used: Stakkert2 for analyzing, stacking, and processing the image. Registax 6.0 was used to intensify the wavelet of the image and Adobe photoshop was used to create the final image. There were 200 sub-frames used for stacking.
