Perhaps someone here could put up a screenshot showing the best 'close-up' look at the movie version Main Generator, where it is seen in a 'targeting display' just as General Veers orders "Target, maximum fire-power". I don't know how important it will be to Adywan in the end, but there are some noticeable differences between the movie version and this other image that has been shown on here. Most notably, at the inside areas of the four prominent sections, where the middle horizontal sections join. I don't know how important that is or not, but there are certainly differences.

Adywan - That reminds me. I really like the shape of the excellent existing 'targeting display' graphic, as well as the green 'co-ordinates' around it. If you are planning on changing the image of the Main Generator shown in it in any way, I hope you will choose to keep the actual graphic as it is. And I'd like to vouch for the existing 'macrobinocular' one that the Rebel Trooper first spots the 'AT-AT leg' on, too.
