The significance of this differential movement is a function of the focal length and your image scale sure but the degree of flexure and the time period over which this movement takes place will depend strongly on the class and design of your telescope and guide scope interface.

Hence OAG

hehe, really ?
, rivals AO ?, at long FLs?

Oh really ?
And a quote from Steve Cannistra
......we don't even need cameras that can cool to -25 C. And by imposing more aggressive cooling on these chips, it is possible that we are increasing the likelihood of experiencing other side effects such as residual bulk image (RBI)
Its OK Mike, you can be wrong. I understand, it proves you are human, dont be embarrised, I forgive you
. We love you mike, its a momentary lapes of reason thats all.

And you too Alex, behave yourself, stop crawling, its silly
