Description

Almost "all night long" exposure for this wonderful galaxy in Leo. Crop 1/3 from original. Version "B" by my good friend Edoardo Radice . Also a close-up of the effect of deconvolution (by PixInsight) is provided (image "C"). The two stars indicated by the yellow arrow are 47" apart (about the maximum diameter of Jupiter).

Quasi tutta la notte di posa per questa bella galassia nel Leone. Circa 1/3 del frame originale. Versione "B" uscita dalle sapienti mani di Edoardo Radice . L'immagine "C" mostra l'effetto della funzione di deconvoluzione di PixInsight. Le due stelline indicate dalla freccia gialla sono separate di 47", circa il massimo diametro di Giove.
