Collimating Baby

 Collimating a Newtonian is the most important part of getting it able to show sharp images.  I was a little unsure how this was going to work on Baby.  

You need to get the diagonal exactly square to the optical axis before using the screws on the mirror cell.  I was waiting for a long socket head wrench to arrive for adjusting the diagonal, the first step in the process.  (I already bought this wrench; it disappeared in the move.)  I was thrilled to get perfect collimation almost immediately!
