C 447 is a reflection nebula, which glows blue as starlight reflects off its gas and dust. Also known as the Dreyer Nebula (in honor of whoever cataloged it), it is thought to be part of the same cloud of gas and dust that encloses the Cone and Foxfur Nebulae. IC 447 is in good company, above is IC 446 while to its left there are the small NGC 2247 and 2245, other fascinating reflection nebulae nests of young and very hot stars. I imaged this splendid cosmic field on Saturday 3 February in the company of friends of the GAS (Amateur Astronomers' Group of Salento) at the Palazzo S. Spirito in Stigliano (MT), the acquisition was carried out with broadband filters, L for the luminance and in bin2 the RGB color channels respectively, finally the narrow band HA (hydrogen) signal from my home observatory on Monday 5th. for a composition in LRGB + HA.
