本次活动主要针对国内受限于海外购书不方便的爱好者，如果希望征订这个星图的朋友，请在此通报一下，大家一起团购也方便些，现在在网上书店上都很难买到了。 我们预计买的星图的价格是在 $40-50美金左右，因为社长考虑用信用卡购买，人民币折兑美金汇率是7：1左右，比外汇汇率略高。价格还要取决于运费，我初步的计算大概单本会在￥400左右，大家做好￥500的准备，这个请社长核实。国外也有高价出的朋友，只是这边没有考虑，太高买回来，大家对我有误会反而不好。
估计数量不会超过8本，可能只能有5本供大家选择！

Review
'Using data from both the Tycho and Hipparcos Catalogues, 81, 312 stars down to magnitude 8.5 are now plotted on 26 charts. This is nearly double the number of the previous version ... The Deluxe Version is spiral-bound and unlaminated. The Field and Desk Versions are available in less expensive unlaminated and unbound format, i.e. loose sheets, or more expensive laminated and spiralbound format ... Sky Atlas 2000.0 is an excellent atlas at a very reasonable price, and is suitable for both beginners and experienced observers.' Gordon Nason, Astronomy and Space
'It is a splendid mid-range atlas.' Ian Genner, Webb Society Quarterly Journal
'... an excellent new edition with changes which are all improvements. Thoroughly recommended for amateurs and I suspect that many professionals will also find it useful.' Cliff Turk, Monthly Notices of the Astronomical Society of South Africa --This text refers to an out of print or unavailable edition of this title.

A must for any stargazer!

由于卖家的价钱是不一样的，只能先报名者挑选权优先。 我想真正爱好者不会计较几美金的差价。
本次活动主要是我设想能帮帮内地的朋友，如果到手的时候数量过多，我考虑保留或者送给天文圈里真正的朋友。再次感谢社长的好心和对大家的关心！
时间方面，请社长分析一下大致的订书周期和中间的易手情况。
