I and my little kid came Qingtiangang to watch the Comet NEOWISE(F3) in the early morning today. I saw the comet nucleus and dust tail in my 10x56 binoculars even the liveview of RX100 very clearly, but couldn’t see the comet with naked eye , i think that was because the clouds were so bright in the dawn. besides the comet, the sun rise was beautiful as usual , and the vivid green of grassland was a gift for eyes.
the Focal length(35) of lense used to image the F3 comet are: 26, 46, 300mm
