No filter	Custom Scientific Blue	Astrodon Blue

Images acquired with an ST-2000XM camera (KAI-2020M CCD with AR coated coverslip) through an AP130EDF scope at native f/6 (no reducer, no field flattener or other rear element).  Images were taken sequentially on the same night of the same star and exposure was made to record approximately the backround values (5 minutes each for the blue filters and 2 minutes for no filter).  The only significant difference in images is the filter used.
