Class:
Constellation: Cyg
Data: mag 8.8 size 2.3'
Position: RA : DEC :
Description:
Ideally position at the zenith. First PN that I can see central star so
clearly. At 30x, hint of unfocused star near the set of stars to the north
that forms an arc. Looks green. A nearby bright double star to the west is
used for focusing. At 60x, definitely a PN, pinpoint 10.8th central star can
be seen with averted vision, still a tiny disc. Round shape at 110x, pinpoint
central star with averted vision. See why it’s name “blinking” because it
disappears (though not completely) with direct vision (but this is true of any
dim object I thought). Still bright at 175x but harder now to see the central
star. At 220x, PN now looks oval with central star now looking a
like “nucleus”. Unbelievably, 293x is the best view making the PN looked
almost like the picture, only the PN is more blurred. Central star is now
clearly seen (more nucleus looking). Still bright. 352x proved too much and
too hard to focus. A definite favorite!
