Solar researchers who only image the Sun with CCD cameras often choose the K-Line for purely research purposes. Sadly, with Calcium K-line filters, many older astronomers are unable to see the lower wavelength and miss out on all the fun. We offer higher wavelength Calcium H-line filters for visual observers so that most clients can enjoy Calcium!
