**************** ENG: During the April 21th 2017 session, during the merdian flip of the Hickson 68, I took the chance to capture two comets, both in Hercules at the time. Single 600s shots, guiding on comet nucleus. No processing beyond curves.

**************** ITA: Durante la notte del 21 aprile 2017, al meridian flip mentre riprendevo Hickson 68, ho colto l'occasione per rapidissime immagini a due comete che in quel momento erano entrambe in Ercole. 10' di posa l'una, guidate sul nucleo. Nessuna elaborazione a parte curve.
