Details:
This wavelength is new to amateurs and its similar to the ionized uv calcium line. However, when an extremely narrow bandwidth is used it will appear similar to hydrogen alpha. This wavelength is used by the National solar observatories. I am the first amateur astronomer in the world to image at this wavelength!
