    It seems VSX has the wrong coords for XO-2 b host star. http://www.aavso.org/vsx/index.php?view=detail.top&oid=161283 VSX show the host star in this coordinates: 07 48 07.48 +50 13 03.3 (117.03115 +50.21757) This coords belong to XO-2S: http://simbad.u-strasbg.fr/simbad/sim-id?protocol=html&Ident=XO-2S The correct position for XO-2 b is: 07 48 06.46 +50 13 32.9 http://simbad.u-strasbg.fr/simbad/sim-id?protocol=html&Ident=XO-2b Regards!

    Ther's a variable star near the exoplanet, be careful not select it to calibrate image. The variable star is VSX J074805.5+501556 (http://www.aavso.org/vsx/index.php?view=detail.top&oid=161089)
