Exoplanet transit HAT-P-20b

This is a photometry measurement of a hot Jupiter transit across a star slightly smaller than the sun originally posted on the Exoplanet Transit Database (ETD) http://var2.astro.cz/ETD/index.php.  Data collected from a C11 EdgeHD SCT, ST8XME ccd, and G11 mount stationed at my front yard.  Since my first exoplanet transit (Wasp-3b) posted earlier, I successfully recorded 70+ exoplanet transits with C11 and C8 SCTs, which can be found on ETD.
