In this paper, we present the results from using image subtraction photometry to reduce a crowded stellar field observed with one of the HATnet telescopes (HAT-5). This field was chosen to overlap with the planned Kepler mission. We obtained I-band light curves for 98,000 objects in a 67 square degree field of view centered at J2000 ({alpha},{delta})=(19h44m00.0s, +37{deg}32'00.0"), near the Galactic plane in the constellations Cygnus and Lyra. These observations include 788 exposures of 5' length over 30-days. For the brightest stars (I~8.0) we achieved a precision of 3.5mmag, falling to 0.1mag at the faint end (I~14). From these light curves we identify 1617 variable stars, of which 1439 are newly discovered.2004AJ....128.1761Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/128/1761CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-tohttp://cfa-www.harvard.edu/~gbakos/HAT/LC/199/ : Catalog and Light CurvesII/250 : Combined General Catalogue of Variable Stars (Samus+ 2004)II/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/128/1761https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/128/1761http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/128/1761https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/128/1761https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/128/1761http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/128/1761GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AJ/128/1761/table1 (HAT Catalog of "Kepler Field" Variables)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AJ/128/1761/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AJ/128/1761/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AJ/128/1761/table1?GETtext/xml+votable180.050000true296.20537537.54988890.0055555555555555564/909 920 5/3615 3635 3641 3644-3645 3647 3658-3659 3684 3688 6/14455 14459 14535 14539 14584-14585 14587 14624 14626-14627 14650 14744-14746 14756-14758 14760-14762 14929 14932-149331.1166583743361574e-19 2.6706780932288093e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AJ/128/1761?format=asciiOpticalInfrareddefaultJ/AJ/128/1761/table1HAT Catalog of "Kepler Field" VariablesPer?
