Yes, that was the other oddity that I was indicating. The instrument appears to be an octant. And as several people have noticed, it has a binocular scope. As for perspective issues from pointing directions, I am confident that all three navigators are shooting the same body, so you can directly compare the angle. In the marked-up screen capture below, you can see that the frame angles make sense.
By the way, I had posted this first in our Facebook celestial navigation group, and Jackson McDonald also noticed that the instrument is an octant.
PS: You mentioned that you "couldn’t make the media bit work". This can be fixed. You need a proper media player. The best by far is the VLC player which is available for free on many platforms. Download it from videolan.org here (beware alternate sources --you want it from videolan.org). Believe me, it's the best choice: according to its Wikipedia article, "as of 2012 VLC topped the sourceforge.net overall download count; as of 2013 more than 1.3 billion downloads had occurred." A billion here... a billion there...
