The Lagoon Nebula ( Messier 8, NGC 6523 ) in the constellation Sagittarius - by Mike O'Day ( https://500px.com/mikeoday ) The Laboon Nebula ( M8 ) is visible to the naked eye under dark skies from most latitudes except the far north. Seemingly covering an area about three times that of the full Moon, M8 actually covers an area somewhat greater than 110 light years and is around 4300 light years from Earth in the Sagittarius-Carina spiral arm of the Milkyway galaxy.

From the album: HEQ5/SW 80ED
I started with these objects almost a year ago. Experience and more equipment make quite a difference. -

Hi all, To date I had been satisfied taking single shots with a DSLR and quickly seeing features of nebulae and fainter stars or moons of planets that I could not see at the eyepiece. Now I wanted to see what I could manage with further processing on a computer, so I took some pictures of M8 with a Canon EOS 700D on a NexStar SLT102 altazimuth refractor. I took about 20 30 second exposures at ISO 1600 and managed to get 6 with reasonably round stars. I then used Siril (because I have Linux on my computer and could not get DSS to run using Wine) to stack these after some issues. Siril appears to need to convert the input files to FITS format and also creates the final stacked image in this same format. It has features to then convert to others like JPEG but I found that the only way I could see the effect of the stacking was to open the final FITS file in KStars' viewer. I used the auto stretch feature of this viewer, then took a screen shot of that to which I applied a Gaussian blur filter and scaled down in size with Gimp. I ended up with mixed feelings at the end of this foray. This work flow is definitely not ideal. The final result reveals more than a single shot from a technical point of view but I do not really like it aesthetically. If the reddish background "speckling" is part of the nebula I would appreciate any advice on how I can get a smoother appearance (or how to remove it if it is noise). Cheers!

I currently am on holiday in my father's hometown, a small island near rhodes called symi.Symj, is a pretty small town,with only about 2000 residents.That means that the light pollution levels must be low. Acknowledging that, i called my friends, grabbed my 10x50 bins(that i got for 20€ from Turkey),and went on my way to find a dark site.About after 20 mins of walking (from the city),i stumbled upon a beach, it was dark, so i went in.There i decided to lay on a sunbed that was there.After looking up(not being dark adapted, my friends just kept turning their flashlights on for some reason), i saw the haze of the milky way stretching from Cassiopeia to cygnus and beyond!I was amazed as i ve never seen the milky way before and smudged it off as clouds until i confirmed it was the milky way from an app! The weird part was that at just straight overhead, was the port ,which had many lights, and as a result the sky appeared half bright and half dark. I turned over at Sagittarius and headed over the lagoon nebula. Brilliant! 3-4 stars in a line surrounded by bright nebulosity.(while still being in the haze!) Afterwards i headed to cygnus,it was a real light show! I saw the milky way layering on top of Cygnus while catching a glimpse of m23 and yet again, failing to see NGC7000 . Then, with the corner of my eye, i detected something moving, then turned over to Cassiopeia to see a shooting stsr!(it was my first time seeing one!!!) Was very brief, yet enjoyable. Right afterwards i turned over at the Perseus double cluster.Magnificent! Appeared as 2 small balls of light , almost connected yo eachother. Finally, i realised that finally, the target i was seeking to observe all year long, M31 was into the area with the light pollution! What a shame! While also being low on the Horizon, I couldnt see it with the naked eye. I observed it with ny binoculars for 10 minutes or so . The core was resolved nicely with some hints of outer nebulosity. Overall a great night and now, i wished i had my 8" dob with me.... (Sorry for any granmar mistakes, im currently typing this at 2 am xD)

Hello Astronomers, As I'm still slowly processing my remaining data captured earlier this year, now I'm sharing with you my image of the Lagoon Nebula exposed in narrowband Hubble palette. To me, the shape of M8 in narrowband resembles the map of Australia... This image was also in the group of captures in exposing the Prawn, Lagoon and Swan nebulae on the night of 5/6 July in OSC natural color. As with the Prawn and Swan nebulae, I decided to spend a few nights capturing SII, HAlpha and OIII data of M8 also, spending 1/3rd of the night imaging time on each of the objects, this way I ended up with data of all three at the end of the imaging sessions. This image was exposed through my Bosma 80mm refractor and the full spectrum modded Canon 40D on nights from 6th till 19th July 2019. The total exposure for all three channels of this image was 1002 minutes. Thanks for looking, Clear skies Mariusz

This led me to wonder if there was a way I could display my images on a single page together with a few notes on the target object as well as few technical details of the capture for those who might be interested. What I came up with a "scrapbook" like page that combines all of these three elements in a single PDF sheet ( or jpeg image) that ultimately I might combine together to form a PDF book that I can share online or send to friends and family. In the meantime, I thought I might post in this thread each page of my work-in-progress towards volume 1 of my Astrophotography Scrapbook. Any and all comments, observations, suggestions and constructive criticisms will be warmly received. Cheers Mike ps. The pages have been sized to fit full screen on an IPAD

Slowly working through my summer crop of data - here's my latest: Please click through on the image for a higher res version. 13x 300s (3 at ISO1600, 9 at ISO800), darks, flats and bias, kit as per sig, DSLR at prime focus, Pixinsight. Conditions weren't ideal hence I only got 13 subs - there were a few scattered fluffy clouds around, though it was clear in between so obvious which subs were affected, and due to time of year and position of an annoying hillside it was setting fairly early for me. Still, as a target it's so bright I don't think it suffered much from lack of data - actually I noticed that after the first 3 subs came in, at ISO1600, that the red channel looked like it was clipping, so dropped it to ISO800 for the rest of the run. The Lagoon Nebula (M8, NGC 6523) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as a H II region. In the foreground is the open cluster NGC 6530. The Lagoon Nebula is estimated to be between 4,000-6,000 light years from the Earth and measures 110 by 50 light years. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued as B88, B89 and B296. It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula. The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (the densest part). In 2006 the first four Herbig–Haro objects were detected within the Hourglass. Just for a laugh, here's the same target I took last year. I guess I'm improving !

Ladies and Gents, may I present.. the Lagoon Nebula Lagoon Nebula (M8) by glowingturnip, on Flickr The Lagoon Nebula (M8, NGC 6523) is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as a H II region. The Lagoon Nebula is estimated to be between 4,000-6,000 light years from the Earth and has an actual dimension of 110 by 50 light years. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material). It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula. The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (brightest part of this image) 12 or so 300s lights (it was setting fairly early for me, would have liked more) at ISO400 (bit of an experiment, think I'll go back to ISO800), flats, darks and bias, equipment as per sig, rubbish unmodded DSLR at prime focus, processed in Pixinsight. I had problems with my red channel with this image which was rather weak, which I put down to the UHC/LP filter I was using (can't remember the make). I didn't really need to use it tbh, I could see the LP dome above the nearest town and was shooting through the top of it, but could have done without really. Fortunately I had some old (out of focus ) data I was able to reinforce that channel with. Hope you enjoy !

Hello Astro people... I'm slowly I'm getting through my captured data from April, June & July as time permits. Now it was the turn to process my Lagoon data... This one is the Lagoon Nebula in natural color.... It's only about 2 hours worth of 2, 3 & 7.5 minute subs at ISO1600 using my Canon 40D. I usually imaged at ISO800, but with is one, and the other two on the same night, I decided to give ISO1600 a go to see whether there will be more noise when comparing to ISO800... The result is that there isn't, it looks every bit as clean as my ISO800 exposures, except with the added benefit of half of the time being spent on exposure... Clear Skies, MG

The Lagoon Nebula ( Messier 8, NGC 6523 ) in the constellation Sagittarious. ( click on image to see larger) The Laboon Nebula ( M8 ) is visible to the naked eye under dark skies from most latitudes except the far north. Seemingly covering an area about three times that of the full Moon, M8 actually covers an area somewhat greater than 110 light years and is around 4300 light years from Earth in the Sagittarius-Carina spiral arm of the Milkyway galaxy. ...... The frames for this image where taken back when I was very new to astrophotography and I was experimenting with camera settings. On this occasion I wanted to see if JPEG images might be easier to process - I was disappointed with the results. Now that I have a bit more knowledge and skill at processing I decided to have another attempt at trying to process the set because I liked the way the JPEG files had retained colour in the stars. I am reasonably pleased with the result; the faint detail in the nebula is not there but I quite like the colours in the centre and in the stars.

Hi all, This is my first post in this forum. I just received a HyperStar for my C14. Weather has natrually not cooperated, but I did manage to get out to take these shots last week. 80 x 20 second subs using a modified Canon T2i 16 flats 16 darks 16 dark flats 16 bias Stacked with ImagesPlus and final tweaking in Photoshop. I still need to work on the collimation for the Hyperstar. I also need to get my polar alignment nailed down so I can increase the exposure times. So far, I really like this f2 imaging! Hope you enjoy the photos. As always, comments and criticisms welcomed. Cheers Tim

Evening SGL, though i would share my first astro mosaic. Taking on this little project was a spur of the moment decision, i made no plans for it until i imaged M8+M20 and thought "hmmmm, a galactic centre mosaic would look pretty tasty!". I then planned to create a 3x5 mosaic of the area totaling in 15 panels. But like i said, without planning it out properly i was left with the Milky Way dropping too low in my sky for me to get anywhere near what i wanted. So i only managed 4 panels... Each panel was around 70-80 minutes exposure time except one which i lost a lot of frames on because of cloud, leaving me with one panel of which the exposure time totaled 45 minutes. The processing and creating a seamless image was hard but this 'dud' panel caused more problems. I had to stretch it first and then bring the rest up to the same levels, if i had managed 70 minutes on this panel, i could of stretched the whole image a bit more without any problems. Each panel was made up of 120 second exposures at f3.2, ISO 800. And here is a couple of the single images... M8+M20, the Lagoon and Trifid And a part of the Pipe nebula, i call this area Barnard City I will be better prepared next year and will hopefully get to finish what i've started! All images were taken with a Canon 1100D and a EF200L on a Astrotrac TT320X-AG Clear skies!
