Another IC 1805

Hi all!

I wanted to revisit the Heart Nebula after imaging it last back in 2009 when I was just starting out with astro imaging. Back then I was shooting RGB with a Vixen R200SS. Since then I've been using an Epsilon 180ed but added a TOA-130nfb to the observatory last winter. What joy this refractor is to use and the data I gather with it is super fun to process. The data was drizzled to double the resolution as I found this worked really well with BlurX. After removing the stars I used LinearFit on the SII and OIII starless masters with Ha as reference before combining the channels, doing a histogram stretch and then a round of NarrowbandNormalization with Ha selected for the lightness parameter. I also blended the image with itself using SoftLight as blending mode in the Imageblend script. I'd highly recommend following the link below where you can chose between several resolutions, - the highest being 19044x12500 pixels.


Clear skies!
