I know that this is not a make or break deal for CIHand typing this out makes me realize more that they all will work fine..but here we go
Ok if I use an ISCO IIIs 1.33x lens and a CIH set up.that's a 2.37?
So no matter the content (assuming I want true CIHno zoom adjustment for each format) I'm physically bound by a 1.78 image chip and a lens that expands 1.33x.
1.78 chip X 1.33 lens = 2.37 projected image
If I'm looking at a 53 tall screen my math tells me this:
2.35 = 124.55 wide
2.37 = 125.60 wide
2.40 = 127.20 wide
So 2.37..or go with a 2.35 and spill .5 on each side?
It seems like a 2.40 screen is just setting up to have very very small black bars on the side or the need to spill a very small bit on top and bottom.
Am I missing anything?
Lastly at a 2.15 TR how much pincushion will I have?
