Sivan 5 and 6 - Seadog Nebula
The first color image to feature Sivan 5 and Sivan 6?
I believe this is the first successful color image of the nebulae Sivan 5 and Sivan 6. Siv 5 is the larger mass at the top. Siv 6 lies beneath it and includes Sh2-287, the bright section bottom center. The swooping red wisp that stretches from left to right and looks like a ship’s hull isn’t officially part of either nebula.
Astronomer J.P. Sivan identified these forgotten nebulae in 1974 from an Hα survey of the Milky Way in which they appeared as a couple of tiny, irregular blots. Apparently, no one has bothered with them since.
Sivan nebulae are large and exceedingly faint: this image spans over 5° of the constellation Monoceros; and total exposure time is 74 hours with narrowband filters. This area has been photographed before, but always with far less exposure time. Thus, they scarcely reveal these Sivan objects at all, not that anyone was looking for them. In fact, even the small, brighter Sharpless objects in this image barely appear in most other widefield images. If you find any that clearly show these Sivan nebulae, please let me know and I will update this page.
...Speaking of blots, in the cosmic Rorschach ink blot test that is interstellar space, to me this looks like a dog (or seal) sitting in a boat with a single sail. So, I call this the Seadog Nebula.
