This was my first visit to Fall Creek Falls for the 2015 Tennessee Fall Star Gaze. It’s a casual get together held at a clearing within walking distance from the Inn. The site is reasonably dark measuring 21.42+ on Friday and 21.31 on Saturday after some thundershowers upped the humidity level. Both nights were good so long as you were prepared for dew.
I spent both nights gathering data on SH2-155; the Cave Nebula. It’s a fairly dark object and I’d like more than the 4.5 hours of exposure time I got on it but a couple technical issues coupled with the early moon rise limited my time….
S 155, also known as the Cave Nebula, Sh2-155 or Caldwell 9, is a dim and very diffuse bright nebula within a larger nebula complex containing emission, reflection, and dark nebulosity. It is located in the constellation Cepheus.
Visually it is a difficult object, but with adequate exposure, makes a striking image. The nebula gets its name Cave Nebula from the dark lane at the eastern side abutting the brightest curve of emission nebulosity which gives the appearance of a deep cave when seen through a telescope visually.
This was my first time to Fall Creek Falls and I was not sure what to expect in terms of amenities. For those of you considering going: Restrooms are a 1000+ ft walk from the site. There are no restrooms at the field, nor is there any power, water, etc. The only things available at the site are trashcans. The Inn, as I mentioned before, offers restrooms, along with buffet meals, vending machines, and accommodations on the lake.
