DescriptionNGC 5307.jpg |
NGC 5307 looks a little strange to me. The nebula shrouding the central star has an interesting, almost nacreous appearance. It reminds me of the inside of a shell of abalone. The whole thing is kind of blurry. Is that because the nebula is dissipating and no longer so sharply defined? The usual knots of bright, glowing H-alpha are once again red in appearance. In blue, some He II (f469n) data seemed quite specifically concentrated in the core of the nebula so I emphasized it quite a bit even though it doesn't glow especially brightly. I went ahead and used the data labeled "heritage" in the HLA. The label makes me wonder if someone else deserves credit for doing some processing before me. Then again, I've been wondering just how much of the data in the archive is automatically processed and how much is done by humans. It seems like a rather thankless job if there are humans doing much of the work.
