This very faint nebula does not seem to have any hydrogen-alpha within it since the HA filter picked up nothing even after combining n hour of data. Even the RGB is very week and it took some effort to get a decent image of SH2-81. I used a small amount of the luminance which was the RGB combined into one. Without it very little would have been seen here. Large fast systems might pick up some kind of structure but it appears this object will not be on the top of any ones imaging list anytime soon. If you do go after this one, I think long sub frames and many of them should produce a nice color image.

Essentially nothing appears in the scientific literature on this nebula, which is located far below the galactic plane.

Sh 2-81 can be clearly seen in this WISE infrared image.
