No, it's home-made as is most of my equipment. White-light only, using Baader filter material. I don't purchase very many commercial items. I've got all the materials I need to build my own coronascope, which is a home-made substitute for a H-a filtered-scope. It uses a diffraction grating to isolate specific wavelengths, instead of a narrow-passband filter. Old-school stuff. On 5/1/07, Ann Blanchard <a.blanchard@ugs.utah.edu> wrote:
