Description

Reflection Nebula + Dust => awesome!

For reasons unknown I hadn't really looked at many Iris images so I wasn't really aware of just how incredible this nebula is! It's got a lot going on and is quite interesting to dig in to.

I reprocessed this in 2023 and was able to bring out a lot more detail in the dust:

GHS only for stars

RGB:

Below is the 2021 processing:
