Moon – Vallis Alpes Comparison 2013-04-21

Comparison of my image of Vallis Alpes taken on 2013-04-21 with an EdgeHD scope vs the Orbiter 4 image from 1967.

The Orbiter 4 altitude varied from 2,100km to 6,000km. The mission cost in 1967 was $163m US, So about $1,2 billion in 2015. My equipment is a little less expensive and i was about 371,000 km way when i took the image.
