tested MD option

Conducted some more trials with SkyTools. I wanted to, once and for all, resolve some unanswered questions about telescope set-up and, in particular, the use of the mirror diagonal option.

I built a new example SCT telescope. I set the view to Mirrored and Flipped, assuming a mirror diagonal was not part of the system. Then, for the associated eyepiece, in the Context Viewer, I activated the Mirror diagonal (MD) option. The views were correct, what they should be.

So, then, I was able to answer the first big question. When I choose the MD option, does it stick? I.e. when I switch away to a different 'scope or different eyepiece within the current 'scope, would the MD option remain active. And it looked like it did stay on. I thought I had noted it switching off before...

The other big question was, would the view be correct now for the camera, with the 'scope configured without a mirror diagonal. Switched to the DSLR view and saw it was normal. So, correct. Simply required rotation of the rectangular field.

It looks like, in the end, it doesn't matter... None of it matters...
