Re: C/2020 F3 (NEOWISE) 10/11 July 2020

Found Neowise F3 Monday evening 20th July at 23.00UT using 11x80 binoculars from our north-facing bedroom window. Easily swept up the comet in binoculars "beneath" the bowl of the Big Dipper but no joy n/eye - the streetlights rob the eye of dark-adaption in an instant. The comet was dimmer and the ...

Re: C/2020 F3 (NEOWISE) 10/11 July 2020

A North-facing bedroom window seems to be a popular observing location these days :D I awoke at 2.00BST and decided to take a peek out of our window. In spite of the three encroaching LED streetlights around us, I immediately saw Capella well up in the NNE so decided to try for Neowise which should ...
