We do not currently offer an elliptical aperture. We are soon releasing (in a week or two) the capability to define any user defined freeform-shaped aperture. An elliptical aperture could be created using this tool. However, the freeform is not as straight forward to use as a circular aperture. Elliptical apertures will likely only help if your telescope has poor tracking and guiding resulting in significantly elongated stellar PFSs. We have it on the feature request to add the capability to specify elliptical apertures that would be similar to the complexity of circular apertures, but that will be a few months down the road.
