Object: Pease 1 in M15
Object data: Planetary inside of M15!

The 10/97 issue of Astronomy mentioned that there is a planetary residing
inside M15, which 
is much tougher to pick out, than let's say the planetary inside open
cluster M46. After all,
globulars are on the outskirts of the galaxy. 

I would suggest using a scope large enough to split M15 to it's photographic
limit. Also, use
high power 200x or more. 

Buried on the NE side of the core, I found that if I used a UHC filter (OIII
didn't work out well), and a 7mm Nagler, I could see that when I "blinked"
M15 with the UHC filter, one "star", or clump of stars 
near a noticeable gap in the core did not dim nearly as much as the rest of
the core. With little prior 
knowledge of where this was supposed to be, I checked a chart, and indeed it
was right where it was 
in the Astronomy article. Again..it just looked like a star which became
more prominent with each flash of the Lumicon UHC narrow band filter.

Thanks!   -Todd
