IC 1805 - Heart nebula

One of the strangest things which may happen to you when imging the skies is finding green objects. While Hanny's Voowerp was an example of a big green discovery, under normal circumstances it means that something is wrong. That is why I strongly colour corrected the image below, because the plain raw data show, that one of the most clearly red nebula of our sky is green. And I'm sure, there was no big discovery hidden here.The second image is not to be taken seriously but I want to show, what Theli and Astroart thought would be the right colour.
