APOD Recognizes GRAS Imager John Ebersole










Fountain Valley, CA (PRWEB) May 2, 2008

NASA's popular astronomy picture of the Day (APOD) (http://antwrp.gsfc.nasa.gov/apod/astropix.html) has featured an image by John Ebersol (http://gras-community.gras.wikispaces.net/GRAS+Profiles) a professor at the University of Chicago. The featured object is NGC 6188. This image is just one of a series of incredible images by Professor Ebersole. Ebersole used one of the GRAS Observatory's (http://www.global-rent-a-scope.com), high-performance telescopes that are part of the global telescope network, to gather the necessary data.

Crescent Nebula widefield
telescope filters

Image by write_adam
Here's the widefield version, resized 50%. See the 100% center-cropped version of this (in my photostream) for info about the super-cool Soap Bubble nebula that was found hiding in plain sight in this field. (Hint: it's just left of center in the lower half of this image.)

The Crescent itself, aka NGC6888, is found hanging out in the Cygnus constellation ~5000 light years away, set amidst a backdrop of huge curtains of roiling gas and dust (the sheets of nebula seen brightest in the upper portion of the image).

It is shaped by shockwaves, as the fast stellar winds from the Wolf-Rayet star at its center collide with the slower moving wind that was ejected by the star when it became a red giant around 400,000 years ago. The result of the collision is a shell and two shock waves, one moving outward and one moving inward. The inward moving shock wave heats the stellar wind to uber-hot X-ray emitting temperatures.

Specs:

Camera = STL11000
Telescope = TMB 130 SS @ f7
Mount = EQ6 Pro
Exposure, Hydrogen-alpha (minutes) = 180 (6 x 30 minute subs)
Location: downtown Toronto, Canada
Date: June 7, 2010
Software = capture and alignment in Maxim DL, post-processing in PS CS2

    Nice! Detailed and sharp!
    I like this object, is in my list for the next to take!

    I’ve added a note to the soap bubble nebula (very faint).

    Great work here Adam , those 30min subs really draw out the detail.
