One of the good things about photos of space is that the subjects normally don't change a lot so reimaging old photos is possible as new techniques are learned. This photo is one of those reimaged pictures. I'm sure there's a lot more I could have done with the photo but I'm going to reshoot this one day.
I included most of the frame I took so it'll include a few more deep space items.
M20, M8, NGC 6544 is on the bottom, M21 is in the upper 11:00 from the Trifid Nebula.
About 20 frames, 30 seconds at f/5.6 ISO 400
This was my first attempt at getting some detail from this target. I've got a long way to go, but it isn't too terrible at this point.

The Lagoon is large and bright, and is one of the few nebulae visible to the naked eye. It appears as a colorless smuge in Saggitarius near the galaxy center. I'm not sure if all the bright stars within the nebula arose from the nebula or if they just shine through. The Trifid is a great example of emission (red) and reflection (blue) nebulae viewed side by side.
The gory details: This was taken with a modified Canon 450D at ISO 1600 and a 500mm lens at f/4 riding piggyback on a Celestron 9.25" scope, which was used as a guidescope. This is 23 images totalling about 51 minutes of exposure. The images were stacked separately into groups of 4, 2, 1, and 0.5 minute exposures, and the 4 stacks were then processed as an HDR image in Photomatix. The image was further processed using DPP and Noel Carboni's tools for Photoshop Elements.

We are looking toward the central region of our galaxy, where the density of stars — as well as of gas and dust clouds — reaches its peak, forming intricate dark structures. This portion of the sky is also rich in emission nebulae, particularly the pairs Eagle–Omega (M16–17) higher up, and Lagoon–Trifid (M8–20) lower down.

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.
Ocasionally I took photo of the Lagoon Nebula, Trifid Nebula, M23 from the window of my apartment, I noticed that there is new star discovered by three Japaneses; Hideo Nishimura (Shizuoka-ken, Japan) - Koichi Nishiyama (Kurume, Japan) and Fujio Kabashima (Miyaki, Japan) in Feb 12th, 2015 now: Nova Sagittarii 2015 = PNV J18142514-2554343
The yellow marker indicate this new star.

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.

Canon EOS 50D, Canon EF 50mm ƒ/1.4 prime @ ƒ/1.4, 3.2 sec. exposure, ISO 3200, 2 sec. shutter holdoff, fixed (non-tracking) tripod, six images, stacked and processed.
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.

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
- tripod
- uglily downsized for laptop memory
- stacked with exposit
- cropped a bit ...

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.

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.
