2015 Tennessee Fall Star Gaze @ Fall Creek Falls (9/4/2015 – 9/5/2015)

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.

 

Norris Star Party – 8/8/2015

It ended up being a gorgeous night at Norris.  The MW was clearly visible and seeing looked reasonably good just based on the naked eye twinkle criteria.

I was able to gather a paltry 3x20min of O[III] and 2x20min of S[II] data on M8 (The Lagoon Nebula) to complete a tricolor Hubble Pallet image before it moved behind a tree….

Norris Lake Star Party – 7/25/2015

The night started off hazy with a big halo around the 68.5% illuminated waxing moon.  I wasn’t that optimistic about the high thin stuff clearing out so I threw the Lumenera monochrome high frame rate planetary camera on the scope instead of the usual deep sky camera and trained the scope on the moon for the public.  I added a wireless game-pad so they could drive the mount around and check out different parts of the moon on their own and hopefully add to their enjoyment.  After most of the guests had left I took a few videos and stacked them.  Unfortunately, the laptop is not setup for planetary imaging; hard drive space is very limited on the small SSD and I had to move each AVI to a flash drive as I took them…

Luckily, it cleared up and the high thin stuff dissipated.  I grabbed the deep sky camera and got to work on M16, The Eagle Nebuka, in Sagittarius.
