from AO to NGAO (part I)

Once again, it has been a long time I did not write anything on this Blog. I am about to fail on my decision to write 2 posts per week in average, so I need to catch up

In January, I mentioned to you that I was involved in a new instrument designed for the Keck telescope called Next Generation Adaptive Optics or NGAO (we love acronyms in our field). What project is all about is the point of this post.
