hello all first post i was browsing wwt which i downloaded the other day and noticed on some star[ish] object, strange shadows. it looks like a central square with 4 arm crossing it like a crossroads. does anyone know what this is? i presume its something to do with the telescope which took the pictures, or maybe some interferance from a satellite or the such? i would post the coordinate but i dont know how to get them perhaps someone knows what i'm talking about? thanks james!
