Picked #comet C/2022 E3 (#ZTF) out of the fullmoon-lit sky right next to #Capella - and surprise: at maximum zoom of the DMC-FZ300 a stellar-like central condensation appears (while the coma is subdued by the bright Moon). Checked with stellarium-web.org: this is NOT a background star! The star right next to the comet has 10.0 mag., by the way. Second (max. zoom) picture is 3.2 seconds at f/2.8 and ISO 1600 (with contrast cranked up) - stars trailing now as declination has gone down to 45°N.
