Heart Nebula - IC1805 Bi-Colour in Narrowband

Recommended Posts

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.

I really like this. The colour palette looks so natural and the image quality looks great. Well done!

Thanks Rico. I think the palette works. This is part of the bi-colour process I did not realise was so flexible. It became apparent early on that does need some testing before committing to a blend or else alot of work can be wasted. My first attempt at this was not very satisfactory.

Terrific..  Good resolution of the core and I love the way you have handled the brightness of the core compared with the fainter outer regions.  Has a great 3d look to it.  Good job!

      Slowly dabbling with narrow band and the processing that is becoming more like art than science 🙂
      I really am enjoying it though, Imaged this in my red zone back garden last night, it's 10 x  300 secs each of Ha Oiii and Sii ( no darks as they looked weird )
      Thanks for looking / feedback.

      I scrapped all the Oiii and Sii data I previously took during a full moon (about 15 hours worth) and retook it all when the moon was a bit smaller at 76%.  Ha was taken during 98% and 67% moon.  All the lights were taken on the following nights: 12th, 19th and 20th September 2019.
      Integration times, all in 600s subs unbinned:
      Ha = 28.33 hours
      Oiii= = 5.67 hours
      Sii = 5.67 hours
       
      The Ha data is really nice, and unsurprisingly the Oiii and Sii is not as strong (or nice).
      I'm missing that (vital) step in my processing routine of getting the Sii and Oiii properly stretched to match the Ha, before combining.  I dont really know how to deal with the weaker data properly.  Any pointers would be appreciated.
      What I do currently:
      All the data is loaded into APP into separate channels/sessions.
      The data is stacked and registered against the best Ha sub
      This produces individual stacks of Ha, Sii and Oiii that are all registered
      Each channel is processed with DPP in APP and then saved as a 16bit TIFF
      Each is opened in PS
      Stars removed with AA and any remnants removed and tidied up
      I then open a blank RGB document in PS
      I paste Ha into Green, Sii into Red and Oiii into Blue
      Adjust the selective colour settings to get 'Hubble palette'
      Adjust levels, curves, saturation until looks ok
      All the Ha Sii Oiii data is then combined together in a single 'super' stack in APP using quality weighted algorithm to create a 'luminance'
      That luminance layer is adjusted using levels, curves, and NC tools such as local contrast enhancement and deep space noise reduction (using masks to apply as required)
      The luminance is pasted onto the above colour layer, and incrementally added using gaussian blur
      Cropped and saved.
       
       
      Here it is anyway   I haven't intended on any more exposure time for this one, but will consider it, if the expert opinion dictates otherwise!

      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.
