  1. Hello Astronomers, I got the Topaz Labs Detail and DeNoise PS plugins and I have to say that they are great... noise is literally seek and destroyed without effecting the detail.... After playing with it for a couple of days I say that the plugins are definitely definitely worth getting. I reprocessed my M16 data from July this year and used topaz detail and denoise to try to get some more detail... I also applied the denoise filter to a JPEG image of the horsehead nebula from last year and, well I think the results speak for them selves. Clear skies, MG
  2. Another try from the same night as M8, this time M16 Eagle Nebula in H-alpha, 7nm filter attached. It came out really nice I think.. Scope: Skywatcher EVOSTAR 80ED DS-Pro Mount: HEQ5Pro Camera: QHY168C Filter: Baader H-alpha 7nm Guiding camera: ZWO ASI120MC Guiding scope: Panagor 400mm 16x200s exposure/ 53min total at -10°C binning 1x1 Clear sky! Mariusz
  3. Another gift of a night for us here on the Central West Coast so I didn't waste it. Against the forecast of bad seeing and cloud cover I was treated to pretty steady skies so I jumped at another chance. I had learned quite a bit from shooting the Trifid nebula the night before as to what the rig needed so I shortened the spacing on the corrector lens ( bye bye rotator) and re-shot my flats into the sky at dusk with a white t-shirt wrapped over the end of the scope. As soon as Mars was into view and the sky dark enough I slewed to it, slightly de-focused and re-collimated the C8. Gotta love Bob's Knobs! Ok with that done I refocused and waited for the real Dark to set in.. Around 11p.m. I calibrated and tested the tracking accuracy of PHD2 and focus using tiny M9. 5 minutes was working but to play it safe I decided to go with 3 minute subs and after a bit of tweeking was ready for my real objective for the night... The Pillars of Creation have always fascinated me ever since the stunning Hubble images brought it so close to us and scientists finally had an understanding of what exactly was going on in this beautiful and amazing area of our sky. After that and since getting into AP it's been a goal of mine for quite a few years now. After imaging for over 3 hours total here are the results using my un-modded Canon and humble late 90's USA made Celestron C8. 35-180 second lights @ ISO 800 20 darks and 45 flats stacked and initially tweeked in DSS then into PS for WB and levels and curves and finally into LR for some slight tweeking and final sharpening. Please give me your thoughts on the processing and final image. Hope you get to capture your dreams as well every night...Look up!

  6. In the last few nights I was able to catch more data of M16. I got much better Ha data (better seeing) and also some OIII and SII data, that I had to stretch quite far). In the end I'm happy with the result (it's at only 20 degrees elevation here...). I did some quite extensive processing, also using star masks and the narrowband data to create natural color stars... TEC140 / QSI583ws 6x900s Ha (4,5nm), 4x900s OIII (3nm), 4x900s SII (5nm)
  7. Hi All, Just sharing my latest image... this time it is the M16... I imaged this at F10 on my 8" SCT hoping that with the higher magnification I would get more detail in the pillars of creation... it's better then the one I've taken about 2 years ago using a f6.3 FR but it didn't come out as well as I hoped it would, the OIII and the SII data seemed to be very dim, so I had to push it more to bring out some nebulosity in that spectrum increasing the noise... I'm starting to think I'm reaching the limits of my modded 40D since my deep sky image quality seems to have stagnated... at least in narrow-band imaging. Personally I prefer the look of the natural RGB image, even though the narrow-band data acquisition was much longer. Image tech specs.... H-alpha: ISO400 7 x 1800s Subs 7 x 900s Subs SII: ISO800 12 x 1800s subs 4 x 2700s subs 5 x 2160s subs OIII: ISO640 4 x 1800s subs 6 x 2100s subs 5 x 1500s subs RGB: ISO400 9 x 630s subs 7 x 350s subs 10 x 150s subs Data captured across 7 nights in June and July 2015. Thanks for looking... Criticism welcome... please be gentle...
  8. Hi everyone, As I setup and started imaging the Cat's Paw nebula, when I checked on the system 30 minutes later I was DISSAPONTED to find that clouds rolled in... I waited for the clouds to clear but no luck... While I was waiting for the clouds to clear before packing up I decided to reprocess my M16 data that I captured across 7 nights in June and July. Here are the reprocessed images... I'm quite happy with these seeing that the data was captured through Baader Ha, SII and OIII filters on a full spectrum modded uncooled Canon 40D, nights are quite cool tho, about the 6 degree C mark so I guess that helped. I concentrated on lowering the amount of purple halos around stars and attempted to preserve maximum detail, the purple halos are still there but not as severe as in the first version. I still have a bit of noise/grain in these images, but when I ran the noise reduction filter I started to lose detail, and the level adjustment that the detail wasn't effected too much the amount of noise reduction was not worth changing. I think this was the best balance between noise and detail. I have AstraImage and it's great, but I heard that Topaz Labs Denoise is a good noise removal algorithm... Has any one used it, if so how does it compare to the likes of MoiseWare Pro, Astra Image and photoshop? Clear skies...
  9. Here is one of the images which never really got off the ground last year. I started in July 2012 imaging the Eagle nebula. It is a difficult target, very low from here, and usually in the murk, and I only had opportunity to gather 9 x 20 mins in Ha for it with my C11Edge. However I had previously taken a much wider field picture of this area, and with the magic piece of software that is Registar, I have combined the old colour data with last years Ha data, which has been used here as a Luminance, not ideal, but better than the 3 hours of data never being used at all. So here's the mono Ha picture, and the mashup with the old colour version. C11EdgeHD@2800mm, Atik 428ex binned 2x2, Baader 7nm ha filter - 9 x 20 mins Full size on Astrobin. Cheers Tim http://astrob.in/36472/ http://astrob.in/36473/

    As processing skills improve its fun to go back and work again on last years subjects so this is my reworking of the Eagle Nebula taken August 2012

  14. Observation 25-26 July 2017 Date: 25-26th July 2017 @ 19:50 – 2:30AEST Location: Backyard Equipment: 14” Skywatcher GOTO Dobsonian, Televue 31mm Nagler T5 , Televue 17mm Ethos, Televue 11mm Nagler T6, Televue 2X Powermate, Baader Neodymium, Baader Contrast Booster, Astronomik UHC filter. The first thing I noticed from the beginning is that there was more sky glow than I would like, it was quite obvious that the seeing won't be perfect. I keep hunting for maximum magnification and detail on planets so before observation I re-collimated the Dobsonian from scratch. This time I put a white piece of paper behind the secondary so it was easier to see if the secondary mirror is circular and centered. Second step was to use the laser to collimate but noticed that when I touched or span the laser, its reflection changed, so using it is pointless without first collimating the collimator (what da?) and proceeded to use the Cheshire. As a final step I tweaked the collimation on Saturn and a nearby star. Saturn: Saturn looked soft and fuzzy. The Cassini division was barely hinting itself in and out of a shade like apparition on the outer edges of the rings. There were 5 soft moons around it, but I knew that the seeing was too poor to properly test the collimation tonight. After a disappointing start tonight when comparing to my hope and expectation, while observing Saturn at 150X, at 20:40 (iPhone time, 20:38 "Star Walk" time) a bright satellite flew past and through Saturn. The flyby was not slow but wasn't as fast as a shooting star either. When checking for satellites on the "Star Walk" app, it turned out to be "Envisat". It is rare views like this that make a view memorable and special, by adding a bit of action to the scene. After seeing that Saturn looked quite soft and with the considerable amount of sky glow, I wasn't expecting to get the best views so I took the lazy approach to observing tonight and, after accurately star aligning the scope, selected the objects above 40 degrees in order from the "Deep-Sky Tour" option on the SW14 hand controller. Lagoon Nebula (M8): M8 was visible the same as I saw it last time I was observing and as before the sky glow killed all of the fine detail that I saw back in May. Again the main part of the nebula was visible, the dark lane was there, with a hint of structure with in it, as well as the faint nebulosity around the main “Lagoon” coming into view at 50X and 100X power. During dark nights, there is a lot more visible, especially detail wise within and around the nebula, but unfortunately tonight, that was washed away. As with most nebulae, the best way to view this nebula is by using the UHC filter. Omega Nebula (M17): At 50X and 100X the “Swan” is easily visible, along with some of the outer nebulae coming into view faintly around the “Swan”, particularly behind it. Higher magnification, 200X, the structure and shading was once again very easily visible within the Swan head and body. The use of the UHC filter is a must on this nebula to see all of the details. Still a lot of detail is visible for such a bright sky glow seeing condition. Eagle Nebula (M16): The "E" shape was quite easily visible, not as obvious as during a darker night but still visible among the stars in and around the nebula. I’m very sure that at 200X magnification and using the UHC filter, I saw the “dark pillar”, the middle one out of the “Pillars of creation”, the one with “squiggle” at the bottom of it in the photographs. At 100X there was a quite obvious dark shading where the dark pillar is situated. At first I thought it might be wishful thinking and talking myself into believing that I’m seeing hints of one of the pillars, as the seeing and transparency conditions are not the best, but the more I looked in the area, the more I was seeing a distinct elongated darkening at the correct spot, just under the two brighter stars within the nebula. Pavo Globular Cluster: The Pavo Globular is a very nice looking Globular cluster. At 200X it looked like a typical globular except that it has, what looks like, more brighter individual stars sprinkled at the foreground with the Globular shimmering behind it, a few scattered stars at the edges and one particularly bright star toward edge at the top left. This Globular is not as big as 47Tuc or the Omega Cluster but at higher power, it looks just as nice and interesting. This Globular is definitely in my top 3 Globular Clusters to view to date and I will make the effort to image it hopefully in the not too distant future. Butterfly Cluster: An open star cluster with a bright orange star within that drew attention to itself. At 50-100X magnification it sits nicely within the FOV of both the 31mm Nagler and 17mm Ethos. The Butterfly Cluster is a medium sized open star cluster and with the orange star glowing within it reminds me of two other objects, it sort of resembles the cluster within the center of the Rosette nebula with a touch of the orange jewel from the Jewel Box cluster in Crux. Trifid Nebula (M20): The nebula was surprisingly easy to see tonight considering the glow, but the dark lanes are easily visible, within the easy to see with direct vision, “Trifid”, the double star in the center is easily split and the blue nebula haze is quite easily visible to the right of the “Trifid”. The best way to see M20 was at 100X and 200X magnification and using the UHC filter, although the wide angle view with the 31mm Nagler did give a nice contrasty view of the nebula floating in space, with the wide angle, it was like looking out of a space craft port hole. Comparing the view of the Trifid Nebula to how I saw it from a dark location through the 8", it looked about the same, so not bad for seeing the same view but from a much brighter and worse seeing condition sky. Globular (M4): M4 is quite a small Globular cluster in Scorpius near Antares on the eastern side. This globular needed 200X magnification to resolve its core into granulated stars. Globular (M5): Another Globular Cluster picked from the SW14 deep sky tour hand controller. This Globular is quite bright and looks quite nice in the eyepiece, definitely a considerable amount brighter than, for example, M4 and M80. This Globular looks tightly packed at the core, where the granulation is visible at 100X very easily, and less dense sprinkling of stars at the edges. This Globular Cluster is a worthwhile object to observe during a night of observation. Wild Duck Cluster: This cluster is something different, heaps of stars quite tightly packed, looking almost like fireflies rather than wild ducks. There was the shimmer visible through it which gave it a “being alive effect", it is a good sight at 50X and 100X magnifications. As most objects, this one would really benefit from a dark transparent sky to have the "fireflies" as sharp pin points of light since tonight it sort of looked soft focused. Globular (M2): Another small globular needing 200X to resolve stars at the core, this one seemed tightly packed. I just had a quick look and moved on. Maybe I should have studied it a bit longer but initially it resembled M4 and other small globulars. Globular (M22): M22 is a bright Globular Cluster in Sagittarius. The Sagittarius and Scorpio constellations have, by the look of it, a lot of different types of Globular Clusters. M22 is almost as impressive as the Pavo Globular cluster, it is almost as bright and big as the one in Pavo which places it in close position four of my favorite globulars to date. At 100X I saw a dense core with less dense randomly sprinkled brighter stars at the outer edges. Definitely worth a visit. Globular (M28): M28 is another smallish Globular, not too dim, and a bit bigger than and not as faint as M4. This Globular looks good at 200X. Southern Pinwheel Galaxy (M83): Tonight the view of the galaxy was disappointing at best, all that was visible tonight was the glow of the core, no spiral arms were visible at all at any magnification, 50X-200X. Not even the “S” shape coming through, simply the sky was not transparent enough and I guess it didn't help for it to be getting quite low toward the west. Saturn Nebula: As the last time I looked at this planetary Nebula, it was a fuzzy greenish oval, looking almost as if it's always out of focus, only knowing I was focused by the stars near it. 300X needed to see a decent size, but still looking like a featureless oval that is poorly focused, UHC filter didn't help either. Looking at the Hubble image is obvious why it is looking out of focus. It is a planetary nebula within a fainter more diffuse nebula with a bar structure flowing through it, so at a lower resolution, fainter monochromatic view, the more diffuse nebula flows into the central nebula resulting with a fuzz oval view. Helix Nebula: The "Eye of God" initially looked like a smokey oval which was quite hard to see with no central star and initially only showed dimmer fuzzy center. I stopped observing at about 23:00 because I wanted to see the Helix Nebula higher up in the sky so I decided to comeback to the Helix later. I left the scope tracking on the Helix Nebula for almost 2 hours, and returning at 01:30 when it was much higher in the sky, I was pleasantly surprised that it was still in the FOV... not center any more but still in the 100X magnified Ethos eyepiece FOV. Using the UHC filter the smokey ring was much easier to see than before, when it was lower in the eastern horizon. The smoke ring was defined with a dimmer center, the top and bottom parts of the ring were noticeably brighter with the central neutron star visible when using averted vision. Some of the main stars that I remember in the image I took a while ago were also visible there around the smoke ring. The view in the 8" did not reveal as much detail even though I tried to observe it in a darker sky condition. Not bad for what I saw during a milky bright sky. I was under the impression that there was little or no difference between the 14" and the 8", but after seeing the difference in the Helix Nebula, perhaps I was wrong, and just have the wrong idea of what 3X light gathering power really means. I wonder how it will look under a dark, crystal clear sky. The view without the UHC filter made the central neutron star just barely visible with direct vision, along with the stars around the nebula but the nebula was a lot less obvious, still hinted at some nebulosity, but the structure was not discernible. Under a darker sky I'm sure the view will be staggering. M80: Much like M4 except a little bit fainter. M80 is near Antares on the other, western side. This Globular Cluster needed 200X to resolve the sprinkling of stars that seem to be more sparse at the edges. M9: This is a small and faint Globular cluster that needed to be magnified 200X to see any granulation through it but it is still small when comparing to The Pavo Globular Cluster, M22 or even M4 or M80. 300X was needed to see it at a decent scale where it was still a fair bit fainter than the other globs I observed tonight but at this power it had quite obvious star separation visible in the form of granulation all the way into the core. Neptune: At 150X Neptune was a tiny, pale blue disc not much bigger than the bright stars near it. There is no hope to see any detail in the atmosphere of Neptune so any more magnification is pointless, plus the atmospheric conditions wouldn't allow for it anyway, but it was a tighter point of light than last time I targeted it. It also was a lot higher in the sky. Seeing was quite poor tonight coupled with a lot of obvious sky glow visible to a level where the sky looked milky when dark adapted, resulting in loss of contrast and transparency causing fuzzy views and lack of details. The poor transparency was particularly visible on the brighter nebulae such as M8. The poor seeing also made it impossible to tell whether tonights careful collimation helped the ability to get crisp detail at above 400X magnification. As night went on, the condition improved slightly but still nowhere near the best seeing conditions which I experienced in May. The slight improvement in seeing conditions, along with being higher in the sky, might have been the reason for the increased details and features that I saw on the Helix Nebula after coming back to it 2 hours later. Looking at the objects I bagged tonight, most of the them, by far, were Globular Clusters so I guess tonight was a "night of the Globular". After not expecting too much due to the seeing and taking the lazy Deep-Sky Tour option tonight, I did get a few nice surprises, namely the Helix Nebula, a possible pillar of creation in the eagle and a few nice and bright Globular Clusters, few of which I saw for the first time. I noticed Pegasus/Andromeda at 02:30 as I was packing up and so I tried to find M31 with the binoculars but it was too low in the north, in the direction of many street lights that washed any hint of it away... I guess I'm situated to far south. If you read this novel of ramblings of a astro-nut to the end, thank you and congratulations. Clear skies.
  15. Here's my latest, hope you like it ! 17x 300s lights at ISO1600, darks, flats and bias, equipment as per sig, modded DSLR at prime focus, Pixinsight processing. I actually took this back in July, but had a frustrating gap in processing when my laptop broke and had to be sent to Germany for repair - I had all the raw files backed up, but not the interim processed files nor the calibration files. There's a bit of coma still showing on this, but I think I've managed to get my spacings right now for some later runs still in my processing queue. The Eagle Nebula (M16, NGC 6611) is a young open cluster of stars in the constellation Serpens. Its name derives from its shape that is thought to resemble an eagle. It contains several active star-forming gas and dust regions, including the famous "Pillars of Creation", photographed by the Hubble Space Telescope (and by me). The Eagle Nebula is part of a diffuse emission nebula, or H II region, which is catalogued as IC 4703. This region of active current star formation is about 7000 light-years distant. A spire of gas that can be seen coming off the nebula in the northeastern part is approximately 9.5 light-years or about 90 trillion kilometers long. The cluster associated with the nebula has approximately 460 stars, the brightest of spectral class O, a mass of roughly 80 solar masses, and a luminosity up to 1 million times that of the Sun. Its age has been estimated to be 1–2 million years. C & CC welcome, hope you enjoy !

    Imaged F10 on a 8" SCT. OIII and the SII data was very dim and I had to push it more to bring out some nebulosity in that spectrum increasing the noise... Hence the purple halos on the NB image. I'll reprocess the narrowband image and attempt to remove the purple by tightening stars in the SII and OIII channels. Image tech specs....
