hi! not the first case i find an astrophoto seems to be mirrored if compared to the GSky imagery. check this apod: apod.nasa.gov/apod/ap170202.htmlor same image from original source: www.fourthdimensionastroimaging.com/NGC1316then look up the objects pair on GSky! (paste NGC1316 to search panel then zoom out a bit) if you check surrounding stars and other details you will find that the astrophoto and the GSky imagery are mirror-pairs of each other. now the question: which one is right? what can be seen in real? i do not dare to think Google would do such mistakes, but then what the heck is it good for to mirror a great astrophoto to make it only the mirror pair of reality? -again: it is not the first case i remember. any ideas? thanks, g

I used to have a graphics program that could reverse images; I used it a fewtimes for astronomy images. But y'know, it really doesnt matter if the images are reversed, it doesnt take away from the beauty of the objects, and it would be reversed anyway if we could travel to the opposite side.

...it would be reversed anyway if we could travel to the opposite side. XD bruuhaha! well, really have laughed my brains out,but of course it would be not. even if we neglect the dimension of time we must not forget dimension the 3 rd. there is no such point of space from where a starscape could be viewed reversed. still I am confused, why is it good (even accepted!) to reverse nature photos...):< *** EDIT:.I just cannot believe it is here again! look Porpoise Galaxy or as NGC 2936 on GSky, then check it on this nasa-apod! it is reversed again! please anyone hear my desperate cry: WHY???

okay, it is my last example: it seems that all recent nasa-apods are mirrored images - I am close to the paranoia that all this just for me not to be able to overlay easily...!(: check image on the apod page above and compare with GSky (NGC 6302) imagery or the photo on wikipedia. at least it is proven -by wiki reference- that GSky imagery is OK.

maybe you can find a replacement image on the web images.
