An important science topic at IANCU is studying variable stars. Variable stars have been studied and surveyed for a large part of the sky due to their importance in understanding stellar properties as well as their importance in estimating distances. However, the crowded Galactic Plane has been generally avoided by most surveys in the past. ZTF however has studied the Galactic plane extensively in g, r and i bands. While these wavelengths are suitable for studying a large category of variable stars, we miss out on the blue end of the spectrum like blue large amplitude pulsators, blue stragglers etc. We try to overcome this problem with the help of CFHT u band. The other major problem of the crowded field is also looked upon with a recently developed method of cross matching sources. Here I present the preliminary results obtained by comparing the light curves for selected variable stars with the newly obtained CFHT data and using the new method for resolution of sources.
