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!
