Comet C2007 N3 (Lulin) tail

Having already seen this comet at its best in the preceeding days (although never really in excellent conditions in Tiana) I could yesterday take some images with the 10 cm apochromatic refractor. With an efective resolution of 3" per pixel, this image will not show most of the detail in the inner comma, but will let you trace the extension of the tail. The images are 75" long each one and calibrated with the usual dark, bias and flat master frames.
