Now that it's April, the iconic summertime objects are starting to rise high enough before dawn to photograph for northern hemisphere astrophotographers. The Trifid Nebula (M20) is one of my favorites -- a flower-like emission/reflection nebula in Sagittarius. I took the opportunity of a spectacular night up at Fremont Peak to image it through a 6-inch f/9 Ritchey-Chretien telescope -- my first night using this scope. It was mounted on an Orion Sirius EQ-G mount and guided with a StarShoot AutoGuider and Orion 50mm guidescope.

This is a composite of 25 exposures of 6 minutes each with a modified EOS 500D camera at ISO 1600. Dark and flat frames were applied. Images were stacked in DeepSkyStacker and the composite image processed in Photoshop CC.

M20 The Trifid Nebula is an H II region in the north-west of Sagittarius in a star-forming region in the Milky Way's Scutum-Centaurus Arm. It was discovered by Charles Messier on June 5, 1764. Its name means three-lobe Shot with Canon 60d unmodified and Sky Watcher Quattro 250 F4.My 1st real go with a guide scope and autoguiding. 17 x 180 sec shots at 800 ISO.

Astro-landscape image of the Lagoon and Trifid Nebula over Steens Mountain in SE Oregon. It was meant to be a Deepscape, but life happens..

I didn't think this image was going to come together. The clouds were supposed to dissipate by 8:30pm and then clear skies for the rest of the night so I could collect lots of data on the nebula to make them really stand out. That is NOT what happened.

Not only did the clouds not clear at 8:30pm, but a thunderstorm rolled through to the west. My lightening app showed lightning and rain heading my way, so I covered up my tracker and camera and ducked into the car. Put "Ridin the Storm Out" on the radio and cranked it up. As it turned out, the storm skirted past me to the west and I neither got wet nor electrocuted. The clouds never fully dissipated, but I got enough images of Lagoon and Trifid peaking through to make an image.

My 1st attempt at these 2 beautiful Nebulae , M20 TRIFID NEBULA on the left side and M8 LAGOON Nebula on the right. I was trying for the Lagoon and was lucky with the lens I used that I managed both in 1 x go. 126 x light frames 17 x dark frames and 32 flat frames, lights were 30 secs each so a total of 1 hour 3mins of data captured and stacked in Sequator software. Canon 60D and Asahi Takumar 135mm f 3.5 old mf lens on a Star adventurer 2i tracker. Very damn happy with this 1st attempt.

The bright area left of the center of this image is the Small Sagittarius Star Cloud or M24. It is fairly large on the sky, so I decided to try shooting it with the Nikon D5100 instead of through the telescope. When I realized how many objects were nearby, it seemed like a good idea to expand the field of view.

There are 10 Messier objects present. These include four bright emission nebulae. From top to bottom, those are M16 (Eagle Nebula), M17 (Swan or Omega Nebula), M20 (Trifid Nebula), and M8 (Lagoon Nebula). Star clusters M25 and M23 are to the left and right, respectively, of the star cloud. Star cluster M21 is just above and left of the Trifid Nebula. M18 is a small star cluster between M17 and M24. In the lower left corner, globular cluster M28 is in view. There are many other NGC and IC objects present, along with dark clouds that represent areas dense with dust which blocks the view of background stars.

This is a stack of 47 60s exposures at a focal length of 90 mm and ISO 2000 from Mt. Pinos, CA. Dark, flat, and bias frames were applied in PixInsight, with registration, stacking, and additional processing in that program. Final touches in Photoshop.

I finally managed to finish processing this beauty. This was a complicated capture with wind, gear malfunctions, and of course haze. This area of milky way doesn't stay above the horizon very long either (at least in this part of the world) limiting the exposure time.

I managed to get 23 7 minute frames over two nights totalling to just under 3 hours exposure time - much less than what I was hoping to accomplish. But I was able to extract reasonable amount of data from the stacked image.

You can clearly see the central region of milky way with M8 Lagoon Nebula (purple blob in the left centre), M20 Trifid Nebula just above it (pale blue). In the top left corner you can see M16 Eagle Nebula and M17 Omega Nebula.

Rho Ophiuchi Cloud Complex covers the right hand side of the image. The Dark River Nebula (B44) extendes all the way from Milky Way to this cloud complex.

And finally Saturn shines brightly over the black dust clouds in the centre of the image.

I've reprocessed this image, as I wasn't happy with the other version I posted. It's sharper, larger, and has less color noise. The colors may be more accurate as well. They are still a little purple heavy, but that's how it came out of the camera. (Make sure to view it in the larger size, as flickr oversharpens these thumbnails, which makes the photo look strange.)

Taken at the Tulsa Astronomy Club's Star Party on the 4th of July, though a few of the exposures used were taken on July 5th, technically.

The bright, purplish area at almost the dead center is the Lagoon nebula, and the little nebula right above it is the Trifid nebula.

This is a stack of four, ~250 second, iso 800 exposures taken with a 50mm lens set to f/4 mounted to my Pentax *ist DL, piggybacked on my old 1970's Celestron C8 telescope. I did a pretty rough polar alignment, but the tracking seemed to work out well enough. I was planning on taking several more photos in order to reduce noise and increase detail, but some clouds rolled in and made any more photos impossible.

Regardless, I'm happy with the tracking, focus, definition in the dust lanes, color, and amount of light I was able to collect in relatively short exposures. Very little to no processing was done to this image besides added contrast and cropping, and the colors are just as they came out of the camera (which are probably a little too warm, but I'll go with it). I just need to work on noise now. It has fairly hot and humid when I took this, resulting in the camera becoming pretty damn noisy fairly quickly. Oh well, it's my best for now.

Next, I may work on a larger composite covering a larger portion of the sky, or attempt some higher magnification widefields with my various lenses (or if my polar alignment improves, some prime focus work on the Trifid or Lagoon nebulas).

I imaged over 3 nights in June 2024.

The Lagoon Nebula (M8) and the Trifid Nebula (M20) are in the constellation Sagittarius.

Both nebulae are estimated to be about 5,000 light years away from Earth, but the exact distance is uncertain.

The Lagoon Nebula is about 100 light years in diameter, while the Trifid Nebula is about 15 light years in diameter.

Appearance: The Lagoon Nebula is faintly visible to the naked eye in dark skies. The Trifid Nebula is a bright object that amateur astronomers love.

Composition: The Lagoon Nebula is an emission nebula and an Hydrogen-alpha region. The Trifid Nebula combines an open star cluster, an emission nebula, a reflection nebula, and a dark nebula.

Star formation: Both the Lagoon and Trifid Nebulae are stellar nurseries, where new stars are actively forming.

Discovery: The Trifid Nebula was discovered by French astronomer Charles Messier in 1764.

Saturn stands out in the star field beside the Trifid Nebula. The open cluster of stars just above and slightly to the left of the nebula is identified as Messier 21. My first attempt at deep sky astrophotography. Made from 12 light and 12 black frames using StarStax and Photoshop. Much more practice needed!

Located in the constellation Sagittarius, approximately 4,100 light-years away in the direction of the center of the Milky Way, lies one of the most famous deep-sky objects of the summer night sky: the Trifid Nebula. Its Latin name, trifidus—meaning "split into three parts"—refers to the nebula's striking three-lobed structure. It was discovered and cataloged by Charles Messier in 1764 under the designation Messier 20.

M20 is the famous Trifid Nebula, a bright colourful emission and reflection nebula that's located in the constellation of Sagittarius. At magnitude +6.3, it's visible with binoculars. This remarkable object not only contains an emission and reflection nebula but also a dark nebula and an embedded open star cluster. When photographed or imaged, it looks spectacular with the emission nebula appearing red, the reflection nebula blue and mixed in between numerous dark lanes. The dark lanes appear to cut through the nebula splitting it into three prominent sections hence the popular name Trifid; meaning 'divided into three lobes'.

Here are some galactic fireworks for you on this July 4th night.

It has been a minute since I had free time and clear skies. For my first imaging session of the summer I chose to capture the Lagoon and Trfid Nebula.

The Lagoon (M8) and Trifid Nebula (M20) are located in the Sagittarius region of the Milky Way. The Lagoon Nebula is also one of only two nebula that are visible with the Naked Eye. Both are emission nebula and are literal star factories, with their superheated gasses creating a beautiful glow. The Lagoon Nebula (left) is located approximately 5,200 light years away and the Trifid Nebula is about 9,000 light years away. Also pictured just above the Trifid nebula is M21 (NGC6531) or “Webs Cross”.

About this image:

A widefield mosaic of M8 and M20. This is a dense region of stars, interstellar dust clouds, and dark nebulae, reflection nebulae and emission nebulae.

The Trifid Nebula (M20)

The Trifid Nebula, a star-forming region in the Scutum spiral arm of the Milky Way Galaxy. The Trifid Nebula (M20, Messier 20 or NGC 6514) is an H II region located in Sagittarius. Trifid means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars; an emission nebula (the red portion), a reflection nebula (the blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85).

The Lagoon Nebula (M8)

The Lagoon Nebula (M8, Messier 8 or NGC 6523), a giant interstellar cloud in the constellation Sagittarius. The Lagoon Nebula is estimated to be between 4000 - 6000 light-years from Earth in the Milky Way Galaxy, and is classified as an emission nebula.
