(IAAC) OBJECT: G213, adn G78 (in M31) Inst: 16" Newt. f/4.59



Observer:  Todd Gross
Your skill:  Intermediate 
Date and UT of observation: 09/22/97, 0800 GMT
Location & latitude: 22 miles west of Boston, Ma. 42.3N
Site classification: Suburban
Limiting magnitude (visual): 4.7 (estimated) 4.7 (est) in vicinity of object
Seeing (1 to 10 - worst-best):  3
Moon up (phase?): Yes, 55%
Instrument: 16" Newtonian-dob w. 96/99% coatings
Magnifications: 98x (19mm Panoptic), 267x (7 Nagler)
Filters used: none
Object:  G78, G213
Constellation:  Andromeda
Object data: Globulars w/in Spiral Galaxy M31
Even in moonlight, I had little difficulty picking out two globular 
clusters within another galaxy! G213 was easier to star hop to, 
but required higher power to make it out. It looked like a 14.5-15th 
magnitude star (indeed it is 14.7) It did not look nebulous. It probably
would have been visible easily in lower power given darker skies, and
better seeing. 
G78 was brighter, but harder to star-hop to. I used a finder chart 
on P. 72 of 10/97s Astronomy magazine. In fact, all stars in the photograph
were visible... A perfect photo down to about mag. 15, with similar
amounts of nebulosity in M31 as to what one can see through the scope. 
G78 was easier to make out than G213, and I could see if through the 19mm 
Panoptic easily, but easier still through the 7 Nagler. It appeared to be
slightly
dimmer than 14th magnitude (again listed as 14.3) Stellar, and not nebulous.
All in all, pretty good for lousy seeing and moonlit skies (the dark lanes were
visible in M31, but not prominent)
