The Trifid Nebula is a combined emission and reflection nebula that is divided into multiple lobes by dark dust clouds. The open star cluster M21 also makes an appearance near the upper left corner of this image.

Photographed on the morning of June 12, 2012 from a moderately dark-sky location using an Astro-Tech AT72ED telescope (prime focus at 430mm, f/6, 72mm/2.8" aperture) and a Sony NEX-5N digital camera (ISO 3200, a stack of ninety-five images each exposed for 30 seconds, producing a total exposure integration time of 47.5 minutes). Tracking for each of the 30 second exposures was performed by a Celestron CGEM mount (no manual or auto guiding, standard sidereal rate after one star polar align).

Image registration, integration, and adjustments done with PixInsight v01.07.06.0793 with final tweaks in Photoshop CS5.

It's the cop nebula!!

Not that great, but OK considering it's only 20min worth of exposure (4x300s) taken from my severely light-polluted back yard. Clouds rolled in and had to get ready for classes too ;) Will have better results to post the weekend after next! Needs dark skies as well as a lot longer exposure and time spent on this object to bring out the blues, obviously!

A Nebulosa Trífida está localizada na constelação de Sagitário e seu nome significa "dividido em três lóbulos". O objeto é uma combinação incomum de um aglomerado aberto de estrelas, uma nebulosa de emissão (a parte em vermelho), uma nebulosa de reflexão (a parte em azul) e uma nebulosa escura (aparentes "lacunas" na nebulosa de emissão, que causam a aparência trifurcarda, estes são também designados como Barnard 85).

A nebulosa foi descoberta pelo astrônomo francês Charles Messier em 5 de junho de 1764, listando-o em seu catálogo como sua vigésima entrada.

É uma região HII, ou seja uma região composta de gás estelar e poeira onde recentemente, em termos astronômicos, começou formar novas estrelas.

Taken on a really good night at Robert Moses State Park. The camera was piggybacked on my 127mm Mak. Unfortunately I set the f-stop on the camera lens to f/1.4. That caused a significant amount of coma in the images. You can see the effect in the stars, particularly near the edges of the images. Rather than nice round circles, the stars look like triangles. I should have made the f-stop f/2 or higher.

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.

What can you learn in your first year of astrophotography .... well, a picture (in this case 6) is worth a 1000 words .... Here is a comparison of my very first astrophotos, fully processed to my abilities when I took them on the left one year ago to the ones I took over the past month and fully processed.

Make sure you view a Larger Version so you can see just how awful my first ones were :-) (though at the time I was happy that I was getting anything)

Yes, I have upgraded equipment, which definitely helps, but technique and processing skills have greatly increased as well.

I have cropped and adjusted the scale so they are comparable in size for comparison purposes, otherwise, no additional editing was done on the photos from my processing a year ago (ugh!)

This comparison just goes to show what a learning curve this hobby has and how much progress you can make in just one year if you keep at it!

Como é bom fugir da poluição luminosa! Nebulosa Trífida (M20). Acho que esta é minha melhor captura de nebulosa até o momento. É uma região formadora de estrelas que mistura uma nebulosa de reflexão e uma nebulosa de emissão, misturando o azul e o vermelho. A foto foi tirada a partir de um local bortle 1/2, o @campingecachoeiradoscristais sem a necessidade de uso de filtros.

It's great to do astrophotography away from the light pollution! Trifid Nebula (M20). I think this is the best capture of a nebula that I made so far. This is a forming star region that mixes reflection and emission nebulae, with the blue and red colors. The picture was taken from a bortle 1/2 site, the @campingecachoeiradoscristais , without any filter.

The Lagoon Nebula and the Trifid Nebula (upper) are found in the Sagittarius Constellation of the Milky Way. The Lagoon Nebula (M8) is mainly hydrogen gas left over from the formation of a star cluster in the middle of the Lagoon. The Trifid Nebula is composed of dust and gas, ingredients for the formation of new stars.

I pushed this pretty hard to get the detail in the dust lanes; also, the banding removal in Aperture's Nik Dfine plugin created some weird little artifacts around bright stars.

The 50mm isn't sharp at all wide open, and worse, it's got some coma. That's why you're looking at a 4:1 reduction of the actual image. Reduces some of the blemishes a bit. Makes me pine for my 85mm ƒ/1.2L, though. Sometimes I'm quite sorry I traded that lens off!

Perhaps when the 60D comes out, they'll have dealt with some of the 50D's noise problems and we won't need banding processing; maybe we'll even have higher ISOs to play with and be able to use tighter ƒ-stops, and consequently get sharper images. Here's hoping. I note Canon rumors posted some tidbits yesterday about the 60D with an air of reasonable authority. So it begins! :o)

This is the "Teapot" area of Sagittarius showing the Milky Way star clouds and dust lanes among the millions of stars and many clusters and nebulae around that region.

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764.[3] Its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.

North on top.

This shows the center of the galaxy near Sagittarius. You should see the Lagoon and Trifid Nebulas at the bottom of the image.

Omega Nebula is at the top.

I shot this image from a dark sky location in the California Bay Area called the Dinosaur Point within the Pacheco State Park. Temperature at night was 77 degrees! Vultures, Skunks and Coyotes kept me company throughout this night of imaging.

This is one of the best locations I have imaged at. Dark Skies, (south, north and west, east is a bit washed out because of city lights from the nearby town (20 miles away) of Los Banos.

Not to mention fantastic weather only possible in California!

Watch out for windy conditions though at Dino point. It was a fantastic day on 7/3 (though unfortunately I wasn't that fortunate on 7/4.

Here is a quick edit of my image of the Trifid Nebula (M20) from the early morning of June 1. This is 7 images at 5 minutes a piece, ISO 800. I only had 6 dark frames, and used no flat frames (made artificial flat within photoshop).

I took these images while at a small "party" with a few friends. I brought the scope because they wanted to see Saturn and anything else I wanted to point at. Finally around 1:30am I decided to attach the camera and show them what a 5 minute exposure of this object looked like. Shortly after my secondary mirror on my scope started to fog up, so I ended at only a few total images to stack.

Will be revisiting this object in the near future for more data.

each astro-pic has its story :

for this one, it was the first time I had a usable horizon for this target, but my tracking system was at home, so I only picked the tripod and made many 2 seconds subs ... other troubles my laptop didn't have enough memory for the D7000 subpics, so I batch-mogrified them all in order to get an idea of the result. there it is :

- 142 x 2s pics at 180mm f2.8

I like this one the best. The Levels and Curves adjustment in PS hasn't blown out the cores in the Nebulas, and by un-checking the "Re-move Hot/Cold Pixels" under the Cosmetic tab in DeepSkyStacker has made the stars better.

A single 30-second exposure was all that was needed to show the dominant features in these two bright nebulae that are located in the constellation Sagittarius. The open star cluster M21 also makes an appearance near to the center left edge of the image.

Photographed on the morning of July 8, 2013 from a moderately dark-sky location using a five-inch aperture, f/4.2 telescope and a Sony NEX-5N digital camera (ISO 3200, 30 second exposure). Image processing performed in Aperture 3.2.4 and Photoshop CS5.

I've now posted an IMPROVED IMAGE that was taken with this same setup, but with image stacking to produce an integrated exposure time of just under 40 minutes.

The centre of our galaxy (the Milky Way), as seen from Sutherland, South Africa.

Edited European Southern Observatory image of an infrared view of the Trifid Nebula.

Original caption: This small extract from the VISTA VVV survey of the central parts of the Milky Way shows the famous Trifid Nebula to the right of centre. It appears as faint and ghostly at these infrared wavelengths when compared to the familiar view at visible wavelengths. This transparency has brought its own benefits — many previously hidden background objects can now be seen clearly. Among these are two newly discovered Cepheid variable stars, the first ever spotted on the far side of the galaxy near its central plane.

A zoomed in look at the Milky Way around Sagittarius.

The "Teapot" of Sagittarius is large in the lower left corner.

The M7 cluster is to the lower right with the smaller Butterfly Cluster (M6) above.

The Lagoon Nebula (M8) is bright to the above left of center.

The dense Sagittarius Star Cloud (M24) is near the upper left corner.

Stacked in DSS with a few darks.

Processed in pixinsight and tweaked in Lightroom.

Taken with my 6D on a regular tripod, 2 second exposures.

This is a selection from a larger image which includes M8 as well. Wanted to feature this picture as a contribution to the Cloudy Nights DSLR astrophoto forum competition for July 2014 for the M20 subject.

Taken with the Pentax K10D (modified and cooled) DSLR on the Stellarvue SV4 telescope. Guided with Orion SSAG on the Stellarvue SV70ED. IDAS HEUIB II filter was used along with the SSF6 flattener.

Stack of 19 subexposures of 1200 seconds each for a total of 6 hours and 20 minutes of integration over 3 nights (July 23, 29, 30). Calibrated with Maxim 5.25 with 64 bias, 9-18 darks (depending on temperature), and 24-64 flats (depending on date). Stacked in DSS with custom rectangle and 2x drizzle stacked. Processed in PixInsight.

Steps in PI were:

Crop to remove ragged edge, Masked stretch script, Histogram stretch to reset black point, Luminance masked noise reduction with the Denoise tool, Masked curves to darken and desaturate the background, and Unsharp mask on the brightest parts.

Exported to Lightroom for final touch (desaturate blue and red a little) and upload.

Note the rings around the brighter stars. The offset rings are from reflections inside the coverglass on the CCD. Because the larger image was framed to balance M8 and M20, the crop is not centered. Thus, the reflections are not centered.

I'm happy enough with this image, I'll revisit it with the whole frame and possibly tone down the blues a bit.

The night started off hazy with a light cloud cover. I was convinced that any observation of deep sky objects was not going to happen, so I covered the scope and got a few hours of sleep. After midnight the improvement in the sky once again enticed me to leave the bedroom and move to the deck to uncover the telescope. The teapot asterism in Sagittarius could easily be seen, even from my suburban house. That was good since my object of interest was the Trifid Nebula, a marvelous bright nebula cut into irregular pieces by channels of dark nebulae, which was located just northwest of the asterism. With the name of “Trifid” one would suspect that the nebula was cut into three pieces, but with the help of nebula filters (a must from my yard), the nebula appeared to be in four sections. M20 is both the Trifid Nebula and an open cluster. The collection of stars makes the nebula sparkle and adds a pleasing dimension to the observation.

Sagittarius (el arquero, símbolo Sagittarius.svg, Unicode ♐) es una constelación del zodíaco, generalmente representada como un centauro sosteniendo un arco. Sagittarius se encuentra entre Scorpius al oeste y Capricornus al este.

Las estrellas más brillantes forman un asterismo fácilmente reconocible, «la Tetera», cuya asa está formada por las estrellas ζ Sagittarii, τ Sagittarii, σ Sagittarii y φ Sagittarii, la tapadera por φ Sagittarii, λ Sagittarii y δ Sagittarii, el cuerpo de la Tetera lo forman ζ Sagittarii, φ Sagittarii, δ Sagittarii y ε Sagittarii, siendo el «pitorro» las estrellas δ Sagittarii, ε Sagittarii —la estrella más brillante de la constelación— y γ Sagittarii.

Sagittarius is a constellation of the zodiac, the one containing the galactic center. Its name is Latin for the archer, and its symbol is Sagittarius.svg (Unicode U+2650 ♐), a stylized arrow. Sagittarius is commonly represented as a centaur drawing a bow. It lies between Ophiuchus to the west and Capricornus to the east.

The constellation's brighter stars (from left to right on the map: τ, ζ, σ, φ, λ, ε, δ, and γ2 Sagittarii) form an easily recognizable asterism known as 'the Teapot'. The stars δ Sgr (Kaus Media), ε Sgr (Kaus Australis), ζ Sgr (Ascella), and φ Sgr form the body of the pot; λ Sgr (Kaus Borealis) is the point of the lid; γ2 Sgr (Alnasl) is the tip of the spout; and σ Sgr (Nunki) and τ Sgr the handle.[1][2]

The constellation as a whole is often depicted as having the rough appearance of a stick-figure archer drawing its bow, with the fainter stars providing its horse body.

Detail of M20 from this shot. I think it came out nicer than M8--being a little higher in the sky helped a bit.
