SZ Cyg is a Cepheid with period ~ 15.1 days. We have about a 60 day spread of images with Y41. Below we present preliminary results in the Blue filter with Y41. Only one reference star is in the fov-but it has mag 9.6, comparable to SZ Cyg and the occurresnce of this reference star is the primary reason we start our Cepheid project with the star. A power pt is being prepared but for now we will just upload a set of images.
