Beter known as IC 1454. Was not apparent w/out UHC at low power. Going thru low power, I went directly to 167X (9mm Nagler). Structure was barely evident. Upon reaching 214X (7mm Nagler), I observed more detail, but still pretty faint. Central star glimpsed (mag 15.0), was seen w/out filter. W/OIII at high power, circular/roundness was evident. moderate size.
