Hello All,

Comet C/2021 E3 (ZTF) appears star-like at magnitude 18.3 in these images. Thankfully very little apparent motion relative to Earth in this thick star field as it is still 727 million km from Earth. To close to magnitude 16 star to see much evidence of coma or tail. Early reports say it may brighten to magnitude 11 in summer 2022.
