Re: First steps with the LISA: question about the best focus
I expect you are already familiar with the sequence of focusing all three (spectrograph,guide and telescope) focal planes, but in case not, here is my procedure: For my own spectrograph, I focus the camera using either a distributed light source such as the daytime sky (when one can have exactly the...
