C/2017 K2 (PANSTARRS) 2022-Jul-02 Dan Bartlett

With added confidence from yesterday's core images (Thanks Doc) I decided to switch out cameras on the RASA 11 (presently using an asi6200mmP 3.9"/px for sky survey work) for the 2.9"/px ASI 183mmP in hopes of catching more detail in C/2017 K2's core. Seeing was slightly worse and the camera has a smaller field of view but I had to try. Here are the preliminary results of this past night's imaging seeing.

Observing info:
RASA 11 620 mm fl
asi 183mmP
336 x 30 seconds (needed short exposures for comet's large proper motion)
