The Lagoon Nebula was peeking out between the trees so I grabbed a few images in SHO. Normally SII never really presents itself well in most objects. But wow, I was stunned at what unfolded. The Lagoon is beautiful in the light of SII. I don't know if it is because I'm using a narrow line at 3 nano meters or what. I thought this bandpass was so impressive, that I had to post it as a stand alone image. There is so much detail in the core that I've never seen before. I'd bet that most people would not be able to identify this image if I hadn't said what it is.
