 - I first put the cheshire eyepiece and I saw something that was clearly not aligned (that's good, that's why we're here).
   - At first glance I'm unsure if I'm supposed to align first the overall picture (guided by the 'crosshairs' of the secondary mirror I can see) or align the image within the secondary mirror.
