NGC 7009 = PK 37-34.1 = Saturn Nebula = PN G037.7-34.5
21 04 10.7 -11 21 49
V = 7.8;  Size 30"x26"

18" (7/28/03): Viewed at 1087x in very good seeing.  The 30" brighter inner oval 
is elongated WSW-ENE and has a noticeable irregular surface brightness (noticed 
for first time) with a brighter, thick rim and darker center (partially 
annular).  Surrounding the high surface oval is a fainter, outer shell although 
interestingly the transition appeared more gradual than at lower power.  The 
ansae were easily visible with very small knots marking the ends of the ansae at 
times.

17.5" (8/10/91): extremely bright, fairly small, very high surface brightness, 
blue-green color, about 30" diameter to the main oval body.  At 412x, the two 
famous ansae are easily visible extending WSW-ENE from the oval disc using 
direct vision.  The western extension is brighter and a very small knot is 
visible at moments with concentration at the tip of the west extension. A faint 
outer shell surrounds the bright disc.  Numerous observations since 9/14/85.

13" (7/16/82 and 9/3/83): similar to 17.5", but the eastern extension is more 
difficult to view.

8" (10/13/81): bright, small, blue-green, high surface brighTness.  Rays or 
ansae suspected, particularly on the western side in excellent seeing at 200x.
