Here is a localization of this image on a broader map, along with names from the official nomenclature. The center of the image is at approx. 30°S, 153°W.

Not close to any toponyms that I have found so far, so the second image places it in an even broader frame, along with the other images we've seen recently, and some of the well known places from 's novels.

@65dBnoise I love that diameter of Cross Crater is 3x larger than the one of Phobos haha

@andrealuck
Yeah, perspective from that orbital altitude far outside Phobos' orbit can create serious misunderstandings, like Phobos' orbit being as far south as 30° (as it appears to be here), which of course it's not.

@65dBnoise yep it took me a while to locate it without any clue in the lbl file

@andrealuck
😮 You located it? I looked for half an hour and I couldn't find a thing, before I realize you did mention Terra Sirenum in your post. But I thought it came from the source of the image. Great job! 👍 !

@65dBnoise Yep on Flickr I also pointed out the Cross Crater and in the ALT text here the Bernard Crater ahah :) Great job to you too!

Excellent presentation!

@65dBnoise I thought about you when I rotated the image to have it with north approx up hahaah

@andrealuck
I noticed! Really, I did notice that you had it turned north, and that you mentioned it. I always read the technical details, but it appears that my brain skipped the first line of the post.

compi,

@65dBnoise @andrealuck Yea, impressive work! Thats so cool!

Yes, @andrealuck shares with us all those beautiful renderings, calling for their integration into the broader universe, real or imagined :-)
