It looks as this comet is beginning to put on a show!

Notes:

My measurements for C/2025 A6 indicates a magnitude of 7.8 but having only a few comp stars in the field is somewhat problematic.
Ion tail extends to the edge of the field.
I used a dual RASA11 configuration with one scope running mono and the second running an OSC.
A superlum image was created using all frames and integrated into the final image.
Looking forward to the Sept 21 data indicating the tail has a large disconnect and much of the tail is missing.
