Description

Comet C/2021 S3 grazed past NGC 6356 before sunrise on August 14th. Due to angle restrictions of Chilescope, there was less than half an hour available for capturing images before sunrise. Additionally, with the long readout time of the 16803 camera, only 24 minutes of exposure were obtained from both the T2 and T3 telescopes. The snr was insufficient, and the background stars were densely packed, making processing extremely challenging. Consequently, the possibility of surrounding dark clouds had to be disregarded.
