Hi! I would like to get some images of NGC 457 (the "Owl" or "ET cluster"). I understand that AAVSOnet is not designed for time-series image requests, so I am assuming that it will not be possible to take enough images to see the variation of V765 Cas (an Eclipsing Binary in the cluster). However, I would still be able to use as many images as it is possible to request in multiple filters to make a color-magnitude diagram of the cluster. The filters for which my software is designed to fit isochrones are SDSS uprime, gprime, rprime, iprime, zprime, B, and V. However, I can get a qualitative idea from other filters depending on availability. Note: I am filling in the form with the magnitudes for V765Cas (the EB). Thank you very much!

IF you can define a future TOM for the EB, we could try a time series.
