NGC 3718 (UMa)

Technical data:    16"f/12-Hypergraph combined with a 15"f/8-Newtonian

                            STL6303 and ST10XME, AO system and AstroDon filterset for colors

                            LRGB (L=24x600s; R=7x600s; G=7x600s; B=7x600s; RGB bin2) - L images scaled to 4800mm (16"f/12)

                            Comments: because of the fact that the object was shot over four different nights and in four different camera angles with two different

                                              focal lenghts, the image lost some data in the upper left corner which was filled up with synthetic background
