Imaged 10th magnitude C/2020 V2 (ZTF) with two RASA11's one using a mono asi6200mmP (20x180s)and the other using the OSC asi6200mcP(21x180s)cameras on February 19th 2023. Made a super luminance channel using all data and from the OSC data produced the RGB channel effectively doubling my exposure time in this L-RGB image. To my knowledge, the secondary tail, is as yet to be confirmed by other imagers, however appears prominent in this image and my Feb 12th image Observational details: Backyard setup scope: 2 x C11 RASA D = 279mm; fl =618mm; F# 2.2 cameras: asi 6200mcP and asi 6200mmP exposure: 21 x180 sec and 20 x 180sec Seeing: 4/5 Transparency: 9/10 Observer: DEBartlett Location: June Lake, California, USA Image InFo (Both): WCS transformation .......
