Geoff, anything I can say in reply you already know ... the mere fact that we can see the Tarantula with the naked eye means that it is very bright at green and blue wavelengths. I often lament that our sensitivity to deep red light shuts down at night. Imagine if we could see all of the H alpha emission nebulae sprawling across the night sky? Now that would be awesome.
