J-J Poupeau - Some great spectroheliograms

Post by Merlin66 »

Hello everyone,

Enjoying a clear view of the sky in Paris, I have taken 4 spectroheliograms near the central lines on the H alpha, H beta, and CaK3 CaK1V.

Good transparency, high frequency turbulence, moderate wind.
Have a nice evening
