attaching an image I took of C/2023 Q1 via LCO-Tenerife on December 26.97 UT (0.35-m Cassegrain, single 180-second image, unprocessed, uncropped (dimensions 30x30 arcmin)). I’ve had some trouble getting measurements from the image (possible software issues), but would “guesstimate” the magnitude to be somewhere around 15-15.5. |
