Matthieu nous offre une belle #astrophotography de la comète #2022E3ZTF obtenue avec sa lunette de 80, f/5,5, CCD ST8. 40 poses de 180s sur 2h, suivi sur la comète. La lumière en haut à gauche c'est #Mars #astronomy #astronomie #comet #ZTFComet #ZTFComet #astrodon

@JohnBarentine Capella really helped. I finally could find the green comet tonight. Berlin (Germany). #ZTFComet

Comet C-2022 E3, shot with RedCat51 on Feb 1, 30 s subs for 15 minutes. The bright moon and clouds made it difficult to shoot, but at least I saw it! First time stacking a comet. Used @Siril_Official with the help of the video by @naz #astrophography #ZTFComet

After a month of clouds with very few hours of clear skies ... I'm finally able to go comet hunting!

The unusual green color is likely due to presence of diatomic carbon, chiefly around the comet's head. The C2 molecule, when excited by the solar ultraviolet radiation, emits mostly in infrared but its triplet state radiates at 518 nm. It is produced by photolysis of organic materials evaporated from the nucleus. It then undergoes photodissociation, with lifetime of about two days, therefore the green glow appears in the comet's head but not the tail. #ZTFcomet
