This object has been eluding me for about one month now because I was using
freebie charts. Tonight with The Sky chart, it was still tough to locate by
star hopping, being so tiny. At 60x, it still looked like a star. At 110x,
the nearby stars are all dimmer, expect the PN. It has blue-green color and
still looked like a lightly bloated star that canít come to focus. At 146x
(still blue-green), better view and definitely a PN. The 60 degree FOV of the
Radian allowed me to see the PN as a ball and the stars to east forming a
racket (5 stars forms a racket and 3 stars form racketís hanlde Ė SAO123243,
GSC443:638, 443:1000, 443:2045, 443:1596, 443:2072, 443:2888). Got impression
of brighter center. At 176x, 220x and 293x, the PN retained its brightness.
Oval shape was detected at 293x and 352x. At 293x, 4 stars form a square (part
of the racket) to the east and fit the FOV! Overall, the size of the PN is
like that of Uranus. Much brighter than M57!
I've discovered that a high-magnification wide-field eyepiece is very useful
in allowing me not only to observe the object, but also to see how it relates
to its surroundings.
