Edited Sptizer Space Telescope image of the Trifid Nebula.
Original caption: The Trifid Nebula is easy to find with a small telescope, a well-known stop in the nebula rich constellation Sagittarius. This penetrating infrared image reveals filaments of glowing dust clouds and newborn stars. The spectacular false-color view is courtesy of the Spitzer Space Telescope. Astronomers use the Spitzer infrared image data to count newborn and embryonic stars which otherwise can lie hidden in the natal dust and gas clouds of this intriguing stellar nursery. The Trifid Nebula is about 30 light-years across and lies only 5,500 light-years away. #cosmos #space #stars #nasa #funfactfriday

A new test using my new Hoya Red Intensifier filter for avoid light pollution influence in the image color.
The orange tone didn't appear this time.
I did a few adjustments in the Deep Sky Stacker (channels and saturation) and Adobe softwares mentioned below.
The .jpg convertion became the image darker but this occurrence can be solved easily.
The only adjust that must be done now is to emphasize the Cat Paw Nebula color (red).
Perhaps less brightness in Ptolomy's Cluster for a better visualization of its colors.

The Lagoon Nebula always gets me on the area inside of it. I'm not sure if the nebula itself obscures some of the stars inside or the earth's atmosphere or light pollution does. Either way, it makes me think my tracking is bad.

The glowing Trifid Nebula is revealed in an infrared view from NASA's Spitzer Space Telescope. The Trifid Nebula is a giant star-forming cloud of gas and dust located 5,400 light-years away in the constellation Sagittarius.The false-color Spitzer image reveals a different side of the Trifid Nebula. Where dark lanes of dust are visible trisecting the nebula in a visible-light picture, bright regions of star-forming activity are seen in the Spitzer picture. All together, Spitzer uncovered 30 massive embryonic stars and 120 smaller newborn stars throughout the Trifid Nebula, in both its dark lanes and luminous clouds. These stars are visible in the Spitzer image, mainly as yellow or red spots. Embryonic stars are developing stars about to burst into existence. Ten of the 30 massive embryos discovered by Spitzer were found in four dark cores, or stellar "incubators," where stars are born. Astronomers using data from the Institute of Radioastronomy millimeter telescope in Spain had previously identified these cores but thought they were not quite ripe for stars. Spitzer's highly sensitive infrared eyes were able to penetrate all four cores to reveal rapidly growing embryos.Astronomers can actually count the individual embryos tucked inside the cores by looking closely at this Spitzer image taken by its infrared array camera (IRAC). This instrument has the highest spatial resolution of Spitzer's imaging cameras. The embryos are thought to have been triggered by a massive "type O" star, which can be seen as a white spot at the center of the nebula. Type O stars are the most massive stars, ending their brief lives in explosive supernovas. The small newborn stars probably arose at the same time as the O star, and from the same original cloud of gas and dust.This Spitzer mosaic image uses data from IRAC showing light of 3.6 microns (blue), 4.5 microns (green), 5.8 microns (orange) and 8.0 microns (red).

A slight zoom-in on the main star-forming region of the Trifid nebula.
Since discovering APLpy to make nicer RGB images from astronomical data, I decided to revisit some images we took with the CTIO 4meter telescope in Chile back in 2011. The data was in the near-infrared, in J (1.0micron), H (1.4 micron), and Ks (2.0 micron) bands. This is the Trifid Nebula in the constellation Sagittarius. It looks quite different in the NIR than it does in optical the blue color is because it is brighter at 1 micron than it is in 2 microns, though you can still see just how reddened the stars behind the dust lanes are. One really striking thing is just how much more light penetrates the dust at 2 microns than it does in the optical, you can see many many more stars through the dust. You really need to zoom in to appreciate some of the detail. Also, compare to a single band grayscale image that I made when I originally took the data (cropped to just show the main star-forming region in the middle):

A zoom-in on the big pillar of gas and dust in the star-forming region of the Trifid Nebula, comparing the near-infrared data that we took with the NEWFIRM instrument on the CTIO 4meter telescope in Chile to the NASA Hubble Space Telescope (taken with the old WFC2 camera, source: hubblesite.org/image/915/news_release/1999-42#) image in the optical. While our pixels are more than 4 times larger, and the atmospheric effects of observing from the ground rather than space smear out the stars, the most noticeable thing about the comparison of these two images is how much more light penetrates the dust in the NIR. We can see many more stars behind the dust, as the 1-2 micron photons are not as easily absorbed by the dust particles, while in the HST image you can only see a handful of stars and the rest are completely obscured. You can also see the jet coming off of one of the new stars as a blue line in our image.
I also made an animated gif of the two exactly overlaid so that you can see the few stars poking through the dust morphing into the many many stars in the NIR:
This NASA/ESA Hubble Space Telescope image of the Trifid Nebula reveals a stellar nursery being torn apart by radiation from a nearby, massive star. The picture also provides a peek at embryonic stars forming within an ill-fated cloud of dust and gas, which is destined to be eaten away by the glare from the massive neighbor. This stellar activity is a beautiful example of how the life cycles of stars like our Sun is intimately connected with their more powerful siblings.

The massive star factory known as the Trifid Nebula was captured in all its glory with the Wide-Field Imager camera attached to the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in northern Chile. So named for the dark dust bands that trisect its glowing heart, the Trifid Nebula is a rare combination of three nebulae types that reveal the fury of freshly formed stars and point to more star birth in the future. The field of view of the image is approximately 13 x 17 arcminutes. #L

M20: The Trifid Nebula in the Constellation of Sagittarius.
Continuing on with my imaging series of summer nebulae, this bright object is actually an unusual combination of an open cluster of stars; an emission nebula (the upper red portion), a reflection nebula (the righthand blue portion) and a dark nebula; the dark lanes running through the center.

The Trifid Nebula is a HII star-forming region in the Scutum spiral arm of the Milky Way combining an emission nebula (Red), a reflection nebula (Blue) and an absorption nebula (dark).
It is a tricky target from the UK as due to the latitude and being a southern summer object, even at its highest point, it is only about 15 degrees above the horizon as it passes the meridian during the darkest part of the night. The image looks slightly out of focus due to the seeing being so bad through the thick air at 15 degrees which means over a 3 minute exposure, everything becomes slightly blurred as it bounces around.

M8 is the so-called Lagoon Nebula, a beautiful cloud of gas, dust and young stars. It covers twice the area of the full moon. M20, 2 degrees north of M8 is the Trifid Nebula. Covering an area about the size of the full moon, it contains some very young, hot stars immersed in gas and dust.
