This image of Comet 2020 F3 Neowise was taken on Monday 20th July 2020 by Peter Branson. A number of separate images of 100 sseconds exposure were taken with an ATIK 314L+ colour CCD camera attached to a TS Photoline ED102 refractor telescope with a field-flattener and Hutech IDAS light pollution filter attached, using Artemis Capture software. The image was enhanced using 'curves' and 'levels' in Nebulosity. The telescope was guided using an Orion Mini autoguider controlled by PHD software. Image © Peter Branson.
