Sharpless 101, the Tulip Nebula is a cloud of dust and gas about 70 light years across in size. It is just a little to the west of the Crescent Nebula and is, like the Crescent, sitting against a backdrop of Hα gas. For this photo, I used four filters that have added to the depth of the image. In addition to the Hα and Oiii filters, I added the Hydrogen Beta (Hβ and Sulfur ii lines. The Sulfur is a deep red and the Hβ is actually a teal/blue line. I am still learning how to bring these wavelengths out in the processing, but I like the added detail they both bring. I may do a before/after with some other nebulas so you can see the difference.
