Description

The Heart Nebula (IC 1805, Sharpless 2-190) subs were imaged back in late September on the same week as my previous image on the Pacman nebula. While guiding was smooth and there were plenty of good subs, for some strange reason this one proved to be surprisingly challenging to process and hence took ages to get around finishing it.

Not sure what caused the processing snags, bortle 8 skies or nearly full moon, but only recently learned few new GIMP processing tricks so gave it another try. While it's far from perfect I'm reasonably happy with the outcome. At least now I can move on to the next one :-) Any suggestions on how to improve the image are very welcome!

Modified Canon 1100d @ ISO 1600, ToupTek Toupcam G-1200KPB mono guidecamera. Lights: 90x180". Calibration: 40 flats, 20x180" darks, 20 dark flats, 20 bias.

Thanks for watching and clear skies!
