I observed the asteroid 7 Iris’ close approach (though not the closest point) to 16 Sgr. These are some of my recordings. The autoguiding was done through a photo tele lens, as the main camera was exposing for seconds at a time. HEQ5, N250/1200, TSO ADC, ASI 224MC  and ASI 178MM(cooled), home observatory, mountpusher
