Most clear nights are now in the winter. Good viewing, but flippin freezing. I spend around 2 months of the year in Las Vegas, so always pack my small scope, great viewing out there if you drive 9,000ft up Mt Charleston.

This is very good new for the G2-MSSM where the LSP is Wino (if one turns off flavor violating effects) and is almost degenerate (\delta m~100-200 MeV) with the lightest chargino. In this case the relic density (which comes out pretty close to the observed value) is generated non-thermally via moduli decays. “The bad news is that the mass difference typically is small – less than 10 GeV in 80% of the cases generated by the scan.”

The larger the telescope, the smaller S/N signals can be seen, because more S and more N are gathered. So the larger scope is like a higher luminosity measurement... But believe me, making amateur astronomers understand that a larger scope does not increase contrast (S/N) is tough! Cheers, T True.

I'll pass along your suggestions to my astronomer colleagues. Unfortunately I won't be able to view anything through the telescope at Northwestern since I am at CERN right now, for most of the rest of this year. Interesting that "contrast" is crucial for viewing galaxies and other far-away objects. This seems closely tied to a combination of S/B and resolution. It would be amusing to describe a narrow Higgs peak on top of a small background as an image with "high contrast"! ;) Thanks, Tommaso! I’ll pass along your suggestions to my astronomer colleagues.

I know that most of these session are organized when there is some moon to see -this makes it easier to have success even if there are a few clouds around, since the moon is always a beautiful target. As for Saturn, it is guaranteed to awe beginners, although unfortunately this year the rings are almost at zero tilt, so one barely sees them, with a diminished return. But there should be other good targets, like M35, M44, and M13 - open and globular clusters which make quite a show even in nghts of close to full moon. As for me, what really triggers me are galaxies in which I can see structure. For this one needs dark skies, so it is almost regularly off limits for reasonable gatherings (i.e. ones that do not aim at deserted places where nobody comes!). In fact, galaxies are faint, and it does not matter how large a telescope is, since what matters is contrast, and contrast requires dark skies. Cheers, T. Hi Michael,
