Object: NGC 6188 Narrowband BiColor
This is a false color narrowband image of NGC 6188 utilizing H-alpha and OIII data in a bicolor combine technique. Dark towers of interstellar dust highlighted against a backdrop of ionized gas create a scalloped effect hinting at a three dimensional perspective. Informally known as the Great Wall of Ara, NGC 6188 is truly one of many fine examples of deep sky wonders in the southern skies.
