Chris Callaway took the following two pictures of Comet C2020 F3 Neowise on the 22nd July 2020 from Coalville. The top image was taken with a Canon 5D and 24-105mm lens set at 28mm on a camera tripod and Star Adventurer Mount. 4 x 30 second exposures at ISO 1000 were used, manually aligned and edited in Photoshop. The image includes Ursa major. The second image was taken using using the same setup but using 3 x 30 second exposures and the lens set at 58mm. The second image was also heavily cropped and again, Photoshop was used for processing.  Image © Chris Callaway.






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.
