Comet Neowise F3
in the Evening sky
July 17, 2020

 
 The
            Comet now is well placed in the evening sky, some 25 degrees
            off the north west horizon at dark. Here we set up on a portable
            mount, at a remote location with a good horizon and used the
            Sigma 150mm f/2.8 macro lens for sharp images of the brightest
            portion of the comet. The tail visually was 15 degrees long and
            spectacular in binoculars. This is a total integration time of
            11.25 minutes at ISO 400.
