Blackwell's List of Galaxies Near Bright Stars
Star Cross-referenced excerpts from Blackwell's List of Galaxies Near Bright Stars (ST June 2011, p. 70) (Galaxies within 1 degree of a bright star - 9 galaxies near 6 stars) Id,Const,mag,B_mpsas,BrightStar,magstar NGC3310 Arp 217,UMa,11,21.6,SAO27724,5.5 NGC4192 M98,Com,11,22.7,SAO100012 - 6 Com,5.0 NGC4254 M99,Com,10.2,22.2,SAO100012 - 6 Com,5.0 NGC4494,Com,10.7,20.3, 41 Com,SAO82659 - 14 Com,v4.8 NGC5676,Boo,11.7,21.0,SAO29165- 24 Boo,5.6 NGC5740,Vir,13.2,22.7,SAO120648 - 109 Vir,3.7 NGC5746,Vir,12.3,22.1,SAO120648 - 109 Vir,3.7 NGC5846,Vir,11.9,20.1,SAO120809 - 110 Vir,4.4 NGC5850,Vir,13.6,,22.5,SAO120809 - 110 Vir,4.4 ================= In the June issue of S and T, Kent Blackwell presents a list of 16 spring galaxies that are near (within one 1 degree) of bright stars. It occurred to me that these types of galaxies might be useful for tracking practice for imaging and for test urban imaging, since there is a bright star in the field. A galaxy might be imaged, even if it is not immediately seen visually. The above comma-separated list covers 9 galaxies near 7 bright stars, but adds the bright star SAO and Flamsteed id numbers omitted from Blackwell's article. ``B_mpsas'' refers to the galaxy brightness in mag. per square arcsec. For comparison, M51 has a magnitude of 8.8 and an apparent brightness in mpsas of 21.1. Not included on Blackwell's list is Leo I (UGC5740), a difficult to see and image dwarf spheroidal galaxy that orbits the Milky Way, that is within one degree of Regulus, alf Leo.
