Category: Planetary nebula.
Constellation: Cyg
Data: mag 8.8  size 2.3'
Position: RA :  DEC :
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!
