Details:
Took a look at AR2767 in high res Ha, CaK & Gband with a 150mm refractor. The forming light bridge material within the umbra appears differently in each wavelength where it is obvious in HA, less obvious in Gband and not visible at all in CaK which is very interesting as completed light bridges tend to be visible in all wavelengths as the spot is a photosphere structure, so this implies maybe that the material involved in building it is not strictly photosphere material and some may be other structures in different layers of our star. Interesting!
