RE: [PSUBS-MAILIST] optronic mast

** My mast camera will not be this fancy but will able to be rotated to

I have also looked into a version using a fixed, vertical mounted video
camera inside a tubular mast, and only rotate the external optics above.

However, this method will produce the exact same effect for the observer
as the Royal Navy submariners had to deal with in World War One: a
periscope image that gradually turned itself upside down as it approached
the aft direction.

The funny thing, though, is that those guys protested when they were first
introduced to a more modern periscope, since they claimed the old system
actually helped them to always know which direction they were looking.

Best regards,
Jens Laland
