C_2023_A3_Tsuchinshan_ATLAS_C14HyperStar_asi2600mcP_32x120sec_2024_06_07_220724PDT_JuneLake_California_USA_DEBartlett

Using an automatically calculated magnitude of 20.49 to calculate the imagesolver in PixInsight, this image really does go "deep" into the starfield. 
I'm hesitant to say that comet C/2023 A3 Tsuchinshan-ATLAS is registering a blueish coma as opposed to the typical greenish coma noted on so many other visitors.  The image was indeed color calibrated using the SPCC with a white reference to a type G2V star.  Perhaps to early to tell, however as I stated, this image does go "deep" into the faintness of the starfield.  Time will tell.
