[Specific] Can someone please optimize this photo of the Earth rising from the moons surface so I can use it as an aquarium background? More details in thread.

I hope to use a better version of this photo for an aquarium background. Going for a Moon landing/Apollo Program theme. It would be great if it could be optimized for a 24in. width by 18in. 16in. height landscape poster that I intend to print and laminate. But most importantly, If I printed it out now.... my tank's filter would be right in the way of the Earth, so if there's any way that the Earth could somehow be re-positioned to the right 2/3rds of the photo instead, it would end up looking much nicer. Thanks :)

Edit: Feel free to alter the Lunar soil.... brighter/more white, or the Earth brighter/more blue.
