_12P_Pons_Brooks_C14HyperStar_asi2600mcP_126x30sec_2023_12_04_184135PST_JuneLake_California_USA_DEBartlett An exceptional night of astrophotography where the final stack, straight from WBPP in PixInsight, showed the average star size to be 2.47FWHM, even with the presence of Vega. Still, processing was a beast due to the ghosted blue reflection of Vega in random places through out the FOV.
