Here, we show He-like triplets of Mg, Si, S, Ar, Ca, and Fe in various orders for θ 1 Ori C. On the left are the triplets in first order, on the right the ones in higher orders, MEG third and HEG second orders. While the first orders provide high S/N power, the significantly higher resolving power of the higher grating orders provides much more details.
