Contemporary Visual Observation(s) for NGC 7078

NGC 7078 = M15
21 29 58.3 +12 10 01
V = 6.3;  Size 12.3

17.5" (8/5/94): extremely bright with a halo extending to about 11' diameter and 
a 3' very bright core containing a 30" intense nucleus.  The halo is very highly 
resolved into fairly bright stars although the stars are irregularly scattered 
in the outer halo.  The halo extends 85% to mag 7.7 SAO 107179 just off the NNE 
edge of the halo and many stars in the halo appear to be arranged in loops and 
strings.  The core is extremely densely packed with stars down to a very small 
intense glow at the center.  This 30" nucleus is concentrated to the geometric 
center.  The faint PN Pease 1 is situated just 30" NNE of center (see 
observation).

13": very bright, very large, very small intense nucleus surrounded by a bright 
core.  Superb resolution down to the center of core.

8": very bright, large, intense core is very compact and dense, surrounded by 
inner halo with many stars superimposed, outer halo well resolved into long 
distinct streamers.  A mag 7.6 star is at the NNE edge of the halo.
