With Orion transiting it is good time to use the "Spectral G" for a little after work binocular education sessions. The Spectral G is an easily seen series of bright stars that run through the spectral main sequence - OBAFGKM. It has nearly the same stars as the Winter G asterism. http://users.erols.com/njastro/faas/pages/winter-g.htm The Forum for Amateur AstroSpectroscopy (FAAS) has a chart showing the sequence: http://users.erols.com/njastro/faas/pages/winterg3.htm The sequence is: O Alnitak B Rigel, Alnilam, Bellatrix A Castor F Procyon G Capella K Pollux, Aldebraran M Betelgeuse This spectral sequence is an easily done after work, outside the warm kitchen door type review. To the FAAS list, I would add the "C" carbon class stars, which require laptop planetarium charting and probably GOTO locating under light polluted skies: BL Ori SAO152427 4.7v Red carbon J062528+144319 W CMa SAO152427 6.7v carbon star J070803-115522 X Cnc SAO98230 6.2v Stellar ruby J085523+171353 Clear Skies - Kurt ================== This post is a continuation of my posts that concerning on my current observing focus: "after-work urban-astronomy". Urban astronomy focuses on using easily set up GOTO scopes across for seasons to view astronomical objects from urban light-polluted skies. As opposed to deep sky object emphasis, urban astronomy concerns bright objects visible with small apetures e.g. - open clusters, double stars, planetary and solar system objects. Having family, friend and work obligations like the rest of you, I will try to limit referenced targets to those observable prior to local midnight.
