RCW 32 The Southern Trifid Nebula (RGB)
RCW 32, also known as GUM 15, is a striking, lesser-known emission nebula located about 3,000 light-years away in the southern constellation Vela.
I used the following software: Astro Pixel Processor for stacking, and PixInsight for processing.
This was the first time I’ve processed this fascinating nebula, and I really enjoyed it. I’m usually not easily satisfied with my own work, but I think the result of this one turned out quite well.
