Fortunately, the weather has not blocked the evening's program, all focused on the Andromeda Galaxy globular, so here's the report.
Night of 07/14/2007 '- Alta Val Trebbia - 1000 m above sea level - seeing 3 / 5 - Optical naturalized - mv limit> 6.
G1: Also called Mayall II, Ngc224 or Andromeda's Cluster is the cluster brightest galaxy of 13.7 mv. Deviates from the galactic plane by about 2.5 degrees apparent and it seems nothing to do with the next system and is presented as a triple star, the cluster is in the center of two stars that are associated with G1 only prospectively. At 93x you can see only a halo undefined, the triple star, and 250x are needed to go deeper i. I did not push very ingeniously with the enlargements and I are limited to observation of the triple, forgetting to fix it. But then what is the separation between the globular and the stars? I read on the internet in an attempt not to try if you can not separate Zeta Acquaris, 2 ", easily within the reach of my paintings. I paid dearly for my amnesia, I'll try next time, trying not to make mistakes.
G272 and G280 : two bones are hard and are close, respectively, 14.7 and 14.2 mv. places on the north Owest an asterism recalls in miniature the constellation Corona Borealis crushed. G272 is easier because it diverted in the area where there is very poor and can not go wrong. For G280 things get a little complicated with the presence of two other very faint stars that come and go south / east. Control several times on the software to search the right portion of the sky; cavaocchi, but there is, in the few moments of calm weather, 250x.
G213: post about 20 'South / Owest of the previous two clusters is contained in a distinctive asterism in a relatively poor and is 14.6 mv; nonstante high magnitude is in a convenient location.
G78: accomplice me a little life with a star-hopping confusing, I lose several minutes to reach the area simulated by Megastar, accustomed always all'Intelliscope I realize that it never acquired a good destrezzza in extricate between asterisms. The only excuse: the triangles are treated and starlets all look the same. This is easy, mv 14.2, close to a star of 14.6 mv that comes and goes with less frequency of globular as evidenced by the difference in brightness of 0.4 points.
G73: just touching the 15 th since MV 14.96 and is associated with M110. As with the previous evening is not too difficult with some ease and emerges as a faint star.
Ngc206: very easy to say the obvious. Using Hyperion is the 67x 21 93x 13 and that the Hyperion is presented as a distinct peripheral thickening of the halo. It has slightly irregular round shape and shows some very slight drop in light.
