Solar Ha filter vs Broadband Solar filter

The club friend, Jim Windlinger made the interesting comparison between Lunt 60mm and IDAS 82mm.

Each result is as expected. But video shows us how each filter re-produces different solar surface. IDAS UHB D5.2 is top of the line as solar broadband filter in the market, which is carefully designed for the safe of visual observing and minimizing the internal reflection for high contrast image.
