Improved Church's Observation (maybe more realistic mod)

you're right -- the observation periscope is has a larger head, lets in more light (in the usn also known as the night scope), has a wider field of view and can tilt to look higher. the attack scope has a smaller head, narrower profile -- a smaller field of view but also less noticeable.

both scopes, afaik, had rangefinding equipment -- that and bearing (and a stopwatch) is all you need to calculate a firing solution.

Are you shure? O well i guest i was wrong affterall

not 100% sure

i think the extra bulk is due to the fact that the attack periscope is an "all heights" system -- i.e. the eye-piece stays at 1 level regardless of the height of the periscope, unlike the observation scope.

but, you may very well be right -- stadimeter mechanics may not have been attached to obs scope. hard to find details -- unless some has a u-boat technical manual. or works for zeiss.

I found something but not everything a want to

Yes the observation perescope has a ability to rangefinding. Yes the atack scope was smaller in view that the observation periscop.
But i` am not shure about the atachment of both into the targeting bearing system (i hope you understand about what i` am trying to say).
Look how the observation scope is instaled - he is moving by some kind of a wire, very strange and interesting.

Well anyway - i think i will try to find some more info about it and then i will rebild the hole thing all over again in the game.

Why delete the firing solution capabilities / in RL a damaged attack periscope meant the only alternative way to work out a firing solution had to be via the observation scope :hmm:

This is correct O scopes were used in many cases of damage
or malfunctions (not just motor failure but fogging or external
damage from collisions etc.)

both scopes I believe had bearing transmitters in all cases and
I believe that in both German and American cases both
scopes were "combat ready" but with the different properties
described above, larger heads vs. smaller heads etc.
