Position: RA : DEC :
Starhopping with 22x makes it easy to find. Already looking like unfocused
star. At 30x, more apparent as blue/green PN. The yellowish orange star
SAO162923 (used as focus star) and blue SAO162938 and the PN form a triangular
shape. More PN apparent at 60x and dimmer than SAO162923. Bright and definite
blue/green color. Definitely PN at 110x, triangular shape still fit within
FOV, round shape. Hint of oval shape at 176x (best view), glimpse of ring
structure. Still bright and green. Glimpse of 1-2 very faint outer stars with
averted vision. Still bright and green at 220x. Can now see one of the faint
outer stars with direct vision popping in/out. At times, looked like vibrating
oval perhaps due to seeing. No central star detected.
Known as the "Little Gem", I really quite agree with this! A favorite!
