, Posa B f/4.0, ISO 3200, tripod. Legnano, Italy.

Con un cielo favorevole ho provato a cimentarmi con un soggetto un po' ostico, la nebulosa Testa di Strega. Anche in questo caso non ho potuto beneficiare di un allineamento con la polare e mi sono dovuto accontentare di singole pose di 15", per un totale di 58' di segnale a 3200 iso. 50 dark per contenere il rumore + 30 flat e 50 bias per compensare eventuali limiti di un'ottica che mi sta regalando tantissime emozioni. Il tutto elaborato su Siril, che a causa di tutti gli scatti mi ha praticamente intasato il pc di file di processo. Ulteriore affinamento su Photoshop e StarNet per creare maschere di livello per esaltare la flebile luminosità della nebulosa e ridurre l'inquinamento luminoso del cielo bortle 7.
