Sun in H-alpha of 07/03/2022 sent on March 16, 2022 (16:52) by Daniele Bonfiglio. 8 comments, 706 views. [retina]

1/100 f/16.0, ISO 400, tripod. Montagnana, Italy.

Solito setup, a causa del seeing medio ho potuto sommare solo 250 delle 1000 foto che avevo nell'arco di 2 minuti. Sono riuscito comunque ad ottenere diversi dettagli, tra cui la regione attiva con enorme macchia solare nel quadrante di SE, e le due lunghissime onde che sembrano due serpenti nel quadrante di NW. Sole del 07/03/2022 ore 10:35 UT, da confrontare con questa: https://gong2.nso.edu/HA/hag/202203/20220307/20220307103510Th.jpg

Hello Serafino, thank you very much! Yes, even of this I made a more "social media" version with a blue background, inverted luminance inside the solar disk and more emphasized bumps ... Maybe I'll post that too... But in the end this is more representative of the real image... Hello, Daniele

Hello Progiuly, thanks for the passage and for the question. The telescope I use is specific for observation and solar shooting in H alpha and has an interference filter (also called Fabry-Perot etalon) that serves precisely for the purpose of selecting only the wavelength H alpha... It is not a simple filter unfortunately... Hello, Daniele
