G73, Glob in NGC-205 & other cool stuff

I was just reading an old article from Astronomy magazine, about viewing
the Andromeda Galaxy. In it, was mentioned the Globular Cluster G73, which
is in NGC-205, and is visible in a 6" scope, if you have a detailed finder
chart. No other info or finder chart was given. Can anyone help me out
with coordinates, or a good chart?

Also, I was wondering if there were any other cool things like this out
there, visible in an 8" scope. I've seen many reports of people observing
things like Globulars in M-31, a Planetary Nebula in M-15, or Einstein's
Cross, but they were all using 18-30" scopes. Way out of my range. Are
there any really cool or challenging things that an 8" dob caould reign in?
I supose 3C 273 would count, but I know of no others. DSO's in other
galaxies owuld be cool, gravitational lenses,

thanks

"Observing Handbook and Catalogue of Deep-Sky Objects" by Luginbuhl and
Skiff has what I think you want. It's in print in paperback and you can
get a copy from Willmann-Bell (http://www.willbell.com) or Amazon.com
(http://www.amazon.com).

G73 is best shown on some of the finder chart images in books like OBSERVING
HANDBOOK AND CATALOG OF DEEP SKY OBJECTS by Luginbuhl and Skiff. It has the
30 brightest globulars in M31 labled. The brightest ones within the main
portion of the galaxy are G76, G78, and G280 (all magnitude 14.2).
G76: R.A. 0h 40m 59.1s Dec. +40 deg. 35' 53" (eq. 2000.0)
G78: R.A. 0h 41m 1.1s Dec. +41 deg. 13' 47"
G280: R.A. 0h 44m 29.5s Dec. +41 deg. 21' 37"


G73 is somewhat fainter (about magnitude 14.9), so it might be somewhat
tougher than the above listed globulars. Computer atlases like Megastar may
also plot some of them. I have seen them in a ten inch, along with one or
two others, although it takes a good dark stable night to pick them out from
amoung the many faint field stars. They are around 3 arc seconds in size and
usually just look like really faint stars with perhaps just a hint of
fuzzyness at high power. A considerably easier M31 globular is G1, which sits
almost two degrees southwest of the large M31 star cloud NGC 206. Its
position is R.A. 0h 32m 46.3s, Dec. +39 deg. 34' 41", and it was imaged and
resolved by the Hubble Space Telescope. It is about magnitude 13.7 and is
physically large enough to show as a non-stellar object in an 8 or 10 inch
aperture (141x).

As for other objects "inside" some DSO's, you should be able to see several of
the star clouds in M33, as well as its brightest emission nebula, NGC 604 (I
have seen that one in an 80mm refractor). Clear skies to you.
