The weather, in the past month, was very bad for astrophotographers in northern Italy: it was impossible to find the right combination of week end, free time and clear sky to go to the mountains to catch some decent shots.
So, when the weather forecast predicted good weather during the week, I decided to take some pictures from my light polluted city sky.
In my opinion the result is surprisingly good considering the location.
I've composed the H alpha and RGB using my latest tutorial

Version B is without H alpha enhancing

Version C star shape restored by my friend Angelo Mazzotti

Negli scorsi mesi il meteo è stato molto inclemente per noi astrofotografi del nord Italia: è stato impossibile trovare la giusta combinazione di week end, tempo libero e il cielo limpido per andare in montagna a scattare un po' fi frames decenti.
Così, quando le previsioni del tempo henno dato bel tempo durante la settimana, ho deciso di fare alcuni scatti dal cielo inquinato di casa mia.
Secondo me il risultato è sorprendentemente buono considerandoil logo di ripresa.
Ho composto Halfa e RGB seguendo il mio ultimo tutorial

La versione B è senza H alfa

Versione C Stelle corretta dal mio amico Angelo Mazzotti
