Description

Gabriela Mistral and northwest corner of Eta Carina nebulae in starless SII. Why this processing? Of the emissions, SII often provides the most striking nebular outlines. However, SII is typically weak, compared to Ha, and is associated with bloated stars. Hence, a longer exposure and star removal are often needed (the latter accomplished here with Starnet++).
