    IC1805 Heart Nebula

    From the album: HEQ5 and Atik 460ex

    My first CCD image My first narrowband image Hubble pallet using Ha, OIII, and SII filters each frame is 20 mins exposure at -10 degs 10 x Ha 14 x OIII 16 x SII
  2. Here is my second submission to the competition. After previously trying to image the Heart Nebula in Broadband it was great to get a chance to have a go in Narrowband. Image details are: Scope: William Optics Star 71 Mount: Celestron AVX Camera: Moravian G2-8300 – Mono Filter: Chroma Ha 3nm 18x1500s exposures (7.5 hours) at -25c 30x Flats & BIAS (SuperBIAS) Imaged over August and October 2017 Processed in PixInsight & Photoshop Thanks for looking.
  3. Here's another wide field Hubble palette nebula, this time the Heart Nebula taken with an FSQ and ASI 1600MM Cool, All images unguided on a 10 mincron GM2000

    The Heart Nebula

    From the album: Deep Sky

    Ha: 66x600s ISO-800 Colour: 23x240s ISO-800 Extra star colour: 18x120s ISO-400 Camera: Canon 450D, modded Scope: Skywatcher 150PDS Mount: Vixen GP Guiding: Orion mini finderguider + SPC900 webcam (unmodded)
  5. My first bi-colour narrowband image with my new OIII Chroma filter. Managed to add 4 hours of OIII to the existing 7 hours of Ha. As always I wanted more OIII data but I think I am done with the Heart Nebula for the moment. Having just processed Ha images for the last half of the year it took alot of extra time and effort to get back into processing colour images, just trying to keep that colour noise under control was a battle! I decided to go with a moody copper colour palette as I have imaged in LRGB previously and fancied a complete change of direction. Scope: William Optics Star 71 Mount: Celestron AVX Camera: Moravian G2-8300 – Mono Filters: Chroma 3nm 18x1500s Ha exposures (7.5 hours) @ -25c 9x1500s OIII exposures (3.75 hours) @ -25c Flats & BIAS Total: 11 hours Processed in PixInsight and PS.
  6. Put together with a collection of Ha subs from the last couple of months of varying quality plus some OIII taken on a couple of hazy nights last week. A fairly quick process with a bit of a half-hearted attempt at rescuing the stars at the end. As ever c and c's very welcome! Paul Tak E130D, G3-16200, chroma 3nm filters on Avalon Linear FR. Ha 20x 1800s OIII 9x 1800s
  7. I had another go at a monochrome Ha presentation - I do like it, you can do a lot more with the tones and textures than you can get away with if it was coloured. Mind you, I don't think I've managed to do a properly decent blend of Ha with LRGB yet... What do you think of these ? (looks like a snake about to strike, don't you think ?) 27x600s Ha, darks flats and bias, equipment as per sig, Pixinsight. This tortured vortex of hot gas is a detail from the centre of the Heart Nebula (IC 1805), which lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. It is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes. This photograph is taken at the wavelength of the glowing hydrogen. The nebula's intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula's centre. This open cluster of stars known as Melotte 15 contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass. And just for fun, here's my first attempt at this target from a few years back (that's not nebulosity in the top corners, it's amp-glow): Hope you enjoy ! Comments and cc welcome, Cheers,

    The Heart Nebula

    From the album: Deep Sky

    Ha: 66x600s ISO-800 Colour: 23x240s ISO-800 Extra star colour: 18x120s ISO-400 Camera: Canon 450D, modded Scope: Skywatcher 150PDS Mount: Vixen GP Guiding: Orion mini finderguider + SPC900 webcam (unmodded)
  9. A couple of clear nights around new moon. That's a while ago! Suddenly both eyes are pointed upwards and this beautiful hobby fires up again (remember; 4 clear nights a month is sort of common in Holland)! Got 2 setups running for 3 nights so lot's of data to be processed. Details: 12inch Ritchey Chretien, operating at f5.5, 1600 mm. of focal length. QSI583WSG, SXV-AOL. Exposures: Halpha: 4h20m., red: 1h30m, green: 1h30m., blue: 2h., luminance: 2h., so over 11h total exposure time, during multiple nights. Red & halpha are mixed, with a touch of halpha in luminance too.

    IC1805 Heart Nebula

    From the album: Messier and NGC Objects

    IC1805 Skwatcher 130pds ASI1600mm-c (-15) 7nm Baader Ha 10x5min lights No darks, flats or bias
  11. I wasn't very impressed with my first attempt at IC1805 with my colour Trius SX26C camera (see my gallery if your interested), I decided it was a bit "flat". So, here's my second attempt, this time with H alpha on a different camera (Trius SX814) and a bit more post processing knowledge. Since the Ha is strong, I decided to blend via PS screen a small proportion of this into both the Luminescence and RED channels. I quite like the variety of star colours within the nebula, so I decided not to push them into the background too much. The final LRGB +Ha image represents about 10 hours of integration time. Alan H alpha LRGB + Ha Lights: L:10; R:10: G:14; B:9 X 600s. Ha: 10 x 1800s. BIAS: 100; FLATS:40; DARKS: 30 all at -20C.
  12. Hi still learning the ropes with my new Hypercam 183c pro i took this image of the heart nebula the other evening, and now I realise I want a scope with a shorter focal length haha. 22x 240s stacked and calibrated in PI. Final touch up in PS 2018 SW ED80 DS pro with Altair light wave 0.8 reducer. Heq5 pro, Altair astro hypercam 183c pro. Guided.

    IC1805

    From the album: Deep Sky II

    Another attempt at the Heart nebula, this time with my Trius 814 camera using a 3nm Ha filter. The Ha was blended into both the L and Red channels via PS screen. I also decided to correct the star colours stars by taking the RGB layer and PS screening this with the LRGB + Ha. I quite like the variety of stars colours, so I decided not to push these into the background too much.

  15. The Heart Nebula - Ha, Oct/Nov 2012 WIP A mere 14x 600 sec exposures This was never intended to be a 'project' as such - I was using it to Beta test the cameras and software.... As I was using the Ha filter, I just happened upon this target as a rich source of Ha data. Taken on/off over three sessions it occurred to me later to try and process what I had - was pleasantly surprised at the results (despite stretching it to the limits!) Give it another 2-4 hours and it should be quite respectable.... pity that I did not take more care in the framing though over the sessions as I have had to crop the top and more noticeably the left edge, thereby loosing some of the subtle edge detail in the outer wall.... never mind though, two hours in, so might just as well add this to the library of ongoing projects! Takahashi FSQ106-ED + dedicated F/R @f/3.6 SBIG STF8300M + Baader 7nm Ha filter. Guided with SBIG ST-i via ST-80 via MicroProjects Equinox Image (beta test) 'Scopebuggied' Takahashi EM400 mount - controlled via MicroProjects Equinox Pro (all on a 17" MacBook Pro) Preprocessed (Darks and Flat frames), aligned and stacked in Nebulosity 3. Processed in Adobe Photoshop CS5 with 'Noel's Actions' The Heart Nebula, IC 1805, Sh2-190, lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula showing glowing gas and darker dust lanes. The nebula is formed by plasma of ionized hydrogen and free electrons. The very brightest part of this nebula (the knot at the right) is separately classified as NGC 896, because it was the first part of this nebula to be discovered. The nebula's intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars known as Melotte 15 contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass. The cluster used to contain a microquasar that was expelled millions of years ago. (Wili) Full Res picture here: http://astrob.in/full/24911/ Thanks for looking as always... Clear skies, Damian
  16. Nice, clear and moon-free last night so I was looking forward to getting some colour subs for various targets, in particular this one! To add to my existing Ha for IC 1805, I gathered some 4min & 2min (lower ISO) subs; the idea of these being to try and maintain star colour on the brighter stars. I combined this colour data with the Ha and came up with the following. This nebula is almost entirely Ha it seems, and it's suprising how little colour data is needed when you have a decent Ha layer for it! (I say this because it works pretty well when only comined with a few of these colour subs) Still, it takes the total integration time over 13 hours which is by far my record! All comments & suggestiong are, as always, very welcome. I'm rather tired today so not sure my eyes are working properly!

  18. It seems that none of my glass optics doesn't want to play nice anymore. I started this 2 panel mosaic while shooting for the bubble area, on Ha, with the Canon 300 F4 L lens. In the beginning it went better, but at some point the IS elements decolimated and I just couldn't luckily align it ok again (by attaching back to the camera and focusing with the IS on and then detaching it). I tried one round with the O3, but then I switched to the Tair 3s. The total on this target is like this: 6 h of Ha on each panel, 1:x h of Canon O3 + 1:15 of Tair O3 on each panel. That means ~17h in total. I might want to try to add more O3, but it's only a hope. The moon comes again and the forecast doesn't seem nice the next days. I need a proper scope. I think now that the Soul is stretched more than the Heart, it didn't seem last night. Full res here: https://drive.google.com/open?id=0ByhJ_xuQxcnjZlQ2Rkw3NUR2S0U Thoughts welcomed. Clear skies, Alex
  19. Here is the Heart Nebula (IC1805) taken in using my William Optics Star 71 f/4.9 refractor, Atik One 6.0 with Baader NB filters. Ha on Friday 2/10/2015 - 8 x 15 minutes. OIII on Saturday 3/10/2015 - 7 x 20 minutes. SII on Friday 9/10/2015 - 8 x 20 minutes. All binned 1x1. All processing done using PI. For some reason I am struggling to get PI to work with batch processing, so no Bias or Flats applied, and it is very clear from the image that it needs the Bias applying, so I hope that at some time I can work out what I am doing wrong and reprocess . Attached is an image and as I have just tried using Astrobin for the first time, also a link to that. All comments welcome http://www.astrobin.com/218344/0/
