Just a simple poll more out of curiosity than anything.
Which eye dominates your vision and astronomical observing? Which hand do you use to focus?
A simple way to test for eye dominance (and this is how we do it in competition shooting) is to make a tunnel with your outstretched hand (curl fingers to make a tunnel). Now, place the tunnel comfortably as if you were aiming down it, BOTH EYES open. Now shut each eye one at a time. The eye that shows NO shift in the placement of the tunnel is the dominant eye, whilst the submissive eye will seemingly shift the tunnel (for me, my right eye shows a shift to the left of the tunnel by about 3 inches, yet the left eye keeps it centralised).
So, for observing, I use my left eye, and prefer, surprisingly, my left hand for focusing(though write right handed). Using my right eye is awkward (but yet I shoot right handed in competition...after blocking my left eye with a patch). On my telescopes, even though RIGHT handed, I will - when I can - change the dual speed unit over to the left side (easy with Taks and Vixens).
Enough ramble - poll gives the options
