Moon testing *A bit of an Update*

You'd need to convert the image to an equirectangular projection.... there's plenty of free panoramic software that could help, although you may need to break up the image into 6 separate cube faces. HDRShopis the only app I know that converts a cross to equirectangular but it works with HDR images. Not sure if it would work with 8-bit.

Well I've spent the last week/week and a half doing studies in ZBrush 3.1 and I've yet to find a way to transfer the sculpt of the obj to another so I've taken a little break and tried starting from scratch and made this (look below) though I can't seem to get to sit right on the TG planet. Any suggestions I've tried my usual spherical project ticks but to no avail.

Note The actual image I'm using for these tests is 2048x2048

I'm not too sure what kind of effect your after but I was able to use spherical mapping with your image to achieve the result below.
The displacement here by the way is set 1,000,000. By the way normally spherical maps are set at a 1:2 proportion (ie: 1600px by 800px) rather than a 1:1 as yours is although this may be due to zbrush, I wouldn't know.

Well done, thats the effect I'm looking for. did you get any stretching around the pole though because thats what I've been getting.

You'll always get some distortion about the poles, its just a matter of limiting it as much as possible, or just not looking at it.
