April 6, 2023, 21:09 UT

The Sun photographed with my Daystar Calcium H filter, 5 inch Surplus Shed refractor, and ASI178MC CMOS camera. The Calcium H and K lines are sensitive to the Sun's magnetism making them useful for studying the Sun's magnetic fields. The region of the chromosphere revealed in calcium images is slightly lower in altitude than the region imaged in hydrogen alpha. Regions of strong magnetism show in these images as the lighter colored regions. The Calcium H line is located in the violet region of the spectrum at a wavelength of 396.9nm. The only advantage of a Calcium H filter over a Calcium K filter is that the H line is easier to view visually than the K line. The white balanced version of this image makes it easier in my opinion to see the magnetic regions.
