Comet C/2020 V2 (ZTF) has picked up its pace by over 1000"/day compared to last month. I've reduced the exposure time to 30 seconds so as to prevent any central trailing at my image scale. I've included an annotated version for anyone (Frank?) interested in the galaxies within the field. Observational details: Backyard setup scope: C11 RASA D = 279mm; fl =618mm; F# 2.2 camera: asi 2600mcP exposure: 243 x30 sec Seeing: 5/5 Transparency: 9/10 Observer: DEBartlett Location: June Lake, California, USA Image details (all) Projection ...............
