Dear Karen,

I have exactly this scenario, but for a faint satellite near a bright planet. I let the planet aperture follow the centroid, and position the satellite aperture relative to the planet aperture (centroiding off). However, I would need to define two different aperture sizes. Is there a way (through scripting, aperture settings files, etc.) to accomplish that somehow?
