Messier 57 is is just coming into a position for a decent look around 11 30 pm. IT is a colourful object and I thought it would give me a good target with which to practice my colour developing in PS/Lightroom. I have read so much about how to produce a LRGB image from the four stacked/calibrated luminance, red, blue and green images, a lot seems contradicatory and some, when followed, gave me colour yes, but not as we know it. I am sure a fair chunk must be put down to me. Anyway, I now have a work flow which gives me colour, sometimes resembling what other people have obtained. Progess of s

My first attempt at M57. I attempted to capture the extended halo by gathering some OIII and Ha data and then blending these into Blue and Red channels, respectively of an LRGB image. The image below represents about 21 hours and was taken with my Esprit 150. Alan LIGHTS: L:13, R:13,G:8. B: 10 x 600s; Ha:13, OIII:14 x 1800s. DARKS:30, BIAS:100, FLATS:40 all at -20C.

Tonight was the best night out in a long time. The last couple of days the sky has been crystal clear, and today is friday, which meant nothing was on the schedule for tomorrow. Scope, filters and eyepieces: Today, I was using my one and only Skywatcher 10" dob, with my collection of explorer scientific 82 degree eyepieces. For the first time in a long time, I also used my CLS filter. Targets/observing: Before I headed out, I decided to have a look at skysafari 5 to see what I should have a look at this clear evening. Tonights list ended up including: M13 M92 M57 M27

Evening everyone , Does anyone know the magnitude of the faint star just outside the Smoke Ring of M57 . Before the clouds rolled in tonight I was trying a new ES 8.8mm in the 200P and M57 looked really well at X 136 magnification , then the thought occurred to try it in the X 2 Barlow which gave a magnification of X 273 and , lo and behold , the Nebula was still clear but this time I could detect a faint star just outside it ( about 1 pm position ) Initially , the reason for trying this high magnification was to try and see the faint centre star but this was not possible tonight ..

Hello SGL , this is my first new topic and it is in relation to M57 in Lyra ... I have tried to see this Nebula in different scopes since starting " telescope astronomy " a couple of months ago but to no avail so far ... Might it just be the time of year with no truly dark skies in Midsummer ? I have had much more luck with DSOs in the form of star clusters , like for example the M29 in Cygnus last night while trying to find the Nebula near by ( again to no avail ) ... The equipment used last night was a Meade Infinity refractor 90mm 600mm f/6.7 and a 40mm Plossl for wide field views .

This target is a pain to process. The dynamic range is huge; it has probably more dynamic range than the Orion nebula. I'm still not quite satisfied. Too aggressive deringing during deconvolution made the stars too soft, and they won't reduce properly. This means having to start from almost scratch to get it right. Still, not too bad so far either. Comments welcome. Data from the Liverpool Telescope on La Palma. This is a HaRGB combination with various exposure times for rgb. Ha at 120 sec/sub. Pixelscale 0.28" per pixel; aperture 2 m

More Liverpool Telescope data I am afraid, but what should a Swede do when the sun has decided to make the nights into twilight this time of the year? For those that may have missed it the Liverpool Telescope is a remotely controlled 2 m RC scope on a mountain top on La Palma, Canary Islands. This image contains more Ha data than most of the others I have processed, which helped a lot to reveal the outer shells of this famous planetary nebula. This is a HaRGB image while most of the other high resolution images of the Ring that I have seen are narrow band images, which may make

First attempt at imaging M57 using an entry-level deep space camera (Orion StarShoot Deep Space Video Camera II). Noisy image but I got the ring with color! -
Hello all Just thought I was post a couple of pictures from a complete newbie. Hope you like them. http://www.astrobin.com/users/gerald%40evans/ Kind Regards Gerry -
I imaged Neptune with my C9.25 and when I finished I thought that I would try a little experiment. Using the C9.25 I imaged M57 with my Canon and 90 20sec exposures with no guiding, flats, darks or bias frames just to see how it would work. DSS stacked 72 of my images and this was the result. Not brilliant but not a disaster either. Obviously not as good as stacking long exposures but it's interesting to see what 24 mins total exposure time can produce. Peter

A prime focus RGB image of the ring nebula M57. I had hoped for a better result but I seemed to have focus issues all night. If I really stretched the luminescence sub-frames I started to pickup details of the nearby faint spiral galaxy IC1296. For more detail the astrobin link is: http://www.astrobin.com/267930-

Hi all thoughtt i'd capture the OIII data for my Dumbell image tonight. I was very lucky towards the end of the run as cloud came flooding in but for some strange reason didn't invade my ounce of sky, despite most of the rest of the sky being covered.. Lucky me!! So.. Taken through the 127mm Apo, guided by the 102ED and imaged on the Atik 428EX through an Astronomik 12nm OIII filter. 120min of data in 12 x 600s subs, binned 2x2. I shall be grabbing much more data in all channels, but i think this is a pretty good start for now, albeit slightly out of focus... Not doing

Hello First passage in this section with three nights of test with the QHY5III-178m in deep sky. Target : M57 I made the images and the first treatments but one of my deep sky specialist colleagues Christian Dupriez (http://www.astrosurf.com/chd/) made the most of these images and even colorized. First night : 5 july 2016 bin2 : One of the film : And Christian's treatment : Second night : 29 july 2016 : Bin 2 Christian's treatment at 150% : And his colour version : Last night : 04 august 2016 bin 1 -

The Ring Nebula (Messier 57) is a planetary nebula in the constellation Lyra approximately 2300 Ly from earh. Planetary nebula are formed when ionized gas is expelled by a red giant star, which was passing through the last stage in its evolution before becoming a white dwarf. Taken in narrowband using the California, France, Hawaii Telescope palette (Hα = Red, OIII = Green, SII= Blue) Unfortunately my OIII data was slightly out of focus the the results is not a good as it could be.

Imaging the Ring Nebula was an old dream, so finally being able to do it was a small but significant pleasure! I am glad I even captured a reddish outer rim. This was the last DSO I imaged on 2016-05-04, and for me also the last DSO in this season, as the sky does not get dark anymore until mid-August here (see even the bright background in the picture). I did many experiments trying to find the right combination of sensitivity and exposure. I ended up using all images I took, with a total of 21 lights and 5 darks. Exposure mixture: 13 at 1600 ISO, 8 at 800 ISO; 11 exposures at 10 second

The Ring Nebula in Lyra; one of my favourite celestial objects and one I look forward to every year. Not only is it bright and colourful, this beautiful object is a perfect example of what will happen to our Sun in a about four billion years. If you look closely you can just see the white dwarf in the centre. 12 x 8 minute exposures at 400 ISO 11 x dark frames 10 x flat frames 21 x bias/offset frames (subtracted from flat frames only) Captured with APT Guided with PHD Processed in Nebulosity and Photoshop Equipment: Celestron NexStar 127 SLT GoTo AltAz mount

Firstly Happy New Year everyone! Afraid I'm far from a frequent poster here on the forums, my last deep sky image through a scope was a DSLR image back in March 2012 ... around the time I stopped using film ... better late than never. Since then I have just made the move from DSLR to CCD during Spring 2015 and thought I would share my first finished effort, image files have been in my computer since September ...just a fun experiment to see what could be resolved along with image scale, the image scale is 100% but cropped very slightly due to stack overlap so about 95% of total sensor ar

This is a reprocessing of data taken on 1st August 2015 in order to try out, learn to use, and see if Maxim DL is any better than Nebulosity. It's hard to say for sure which is the best at this stage as both have their pros and cons but I quite like the result of this test on a nice easy target. 17 x 4 minute subs at 800 ISO 9 x dark frames 11 x flat frames 24 x bias/offset frames Post processed in Photoshop

One of my favorite planetary nebulae is rising in the northeastern sky (above that big oak tree)! The ghostly M57, the Ring Nebula, approx. 2300 light-years away and between 6,000 and 8,000 years old (when the outer layers of the parent star exploded), shot on the Orion Starshoot Deep Space Camera II (at maximum sensitivity setting in color) through the Orion StarMax 127. Original music: "Apochromatic (dub version)". Enjoy! Reggie

Hi all! Yesterday good weather, so had my first go at drift alignment with my new reticulated eyepiece. I took my time to figure out well the various steps in the right order, etc... At one time, pointing a star in the east, I think I overdid the correction on the Altitude, because the star started drifting a lot, so I started again from the beginning... As always a learning curve! :-) But I had fun doing it. It took me a lot of time, but finally I got to shooting some subs, and these are the results: M57 @ 38 second subs: M13 @ 63 second subs: The usual coma problem is visible, but I am nev
