SH3's Binocular zoom and periscopes and others

I have discovered how to add/change/modify zoom levels and was wondering if the binocular on the real german subs was variable power or not? If so, what was the power range of them? Were they different for each sub?
I'm hoping the power range was variable because it's time to implement this!
How about the scopes? Did they only have two power settings? Or did they have more than 2?
Deck gun....what should the zoom levels be for this? And the AA guns?

I believe the German Periscopes (attack scopes) were variable from 1x to 6x optical zoom.

I recall reading somewhere that, In game, 10x is modelled in the attack scope to make up for the drawbacks of computer monitors and clarity vs. the human eye and real-life conditions.

The best WWII German binoculars (i.e. the captains pair) were 10x optical zoom IIRC.

Yes IIRC the 10x zoom was added in TGW from the stock 6x to compensate for the fact tis played on a PC and not using Mk1 eyeballs in RL

Results so far are very positive. Variable power can be modeled for the attack, obs scope, and binoculars. There is one little bug currently but I'm sure I'll find a way to fix it...;)

I think the observation scope wax 1x to 4x in RL but had a much wider viewing area as seen thru the scope.

I would think that the obs periscope had more of a viewing than just 1-6..but thats just me...I would like to see the eyes on the person im about to add to the chum

@ Racerboy: These questions can be answered by Hitman; he really know :know: . Is it possible improve deck gun' gunsight? SH1 style was great!
Cheers!

I'm not familiar with SH1's style of gunsight. Can you show me a screenie? If so I'll see what I can do.

Here's what I've been able to do thus far:
Currently I have the attack scope with a variable power from 1x-6x with 0.1 increments. The obs scope is variable power from 1x-10x with 0.1 increments.
Now how about the UZO? Was it variable power? And from what range?
The binocular?
Hitman, can you give me some of your knowledge please?

oh yeah, anybody want to test what I have so far? Some feedback would be great!

sure ill look at what u got...get your pm?

Of course my friend. Please send me a Dl and i will have an look on it!:up:
Kind regards

Attack scopes: Both old model and Standsehrohr 1.5x and 6x zoom

Observations scopes: There's lots of versions here, monocular, binocular and converted bincoulars. AFAIK mainly also with 1.5x and 6x zoom. Never seen a 1x/4x zoom version, though it probably existed.

UZO and bridge lookouts binoculars: Fixed 7x

Differences between observation and attack scope:

1) Observation scope had larger head, which allowed larger filed of view and better night observing (Captures more light) but in turn was easier detectable.

2) Observation scope tilted till 90º upwards for observing airplanes

Both had otherwise same gadgets (Double image stadimeter, AOB finder by turning 90º right the double image stadimeter, etc.)

Hope that helps

GENERAL NOTES:

A marine binocular is a binocular that is used onboard a ship or boat and as such, it will have some fairly specific features. The vast majority of marine binoculars will be the classic 7x50, although other sizes can be used if they have the necessary features.

MAGNIFICATION - (the first number in a binocular)

- Because the deck of a ship or boat is not a stable observing platform, magnification must be kept low for the sake of steadiness. 7x is by far the most popular magnification in a marine binocular and for good reason. A 7x binocular is easy to hold but also powerful enough to be a serious observation tool. Higher magnifications can be used, but unless they are combined with IS (image stabilization) systems, any gain in image detail may be lost to image unsteadiness. In fact, under marginal conditions, you may see more detail with a steady 7x than a shaky 10x.

OBJECTIVE SIZE - (the second number in a binocular)
- The classic 7x50 marine binocular will have a 50mm lens. This is not just a matter of image brightness, though for night use, the 50mm objective will transmit more light than smaller objective. A 50mm objective, when combined with 7x magnification also produces a large exit pupil - the beam of light that leaves the eyepieces. This large exit pupil is much more forgiving than a smaller exit pupil when the eyes are not lined up precisely on the eyepieces, as might happen when you try to observe form the deck of a moving boat.

PRISM TYPE

- The classic 7x50 marine binocular is a porro prism, though, optically there is no reason a roof prism could not be used. The porro prism body, however, has more room to accommodate extras like a rangefinder and compass that are often found on a marine binocular. The robust body of a porro prism may also provide a firmer grip during inclement weather. The best porro prisms will be made of Bak-4 glass.

FOCUS TYPE

- Both IF (individual eyepiece focus) and CF (center focus) systems are found on marine binoculars.
- IF offers the freedom from focusing when viewing objects at medium and long distances - the usual range for marine use. Once set for your eyes initially, an IF binocular needs no focusing for objects beyond 30 or 40 yd. Just raise the binocular to your eyes and look. The advantage on the deck of a moving boat is obvious here. IF focusing systems are also the easiest to seal and make waterproof and they have fewer moving parts than CF systems. For this reason, they are also popular with the military. (Our military uses a version of the Steiner 7x50)
- Center focus is a more versatile system. If you plan to use a binocular at all ranges, from close-in to far away, say for birding or other applications, this is the system to choose.

I thought the scope in RL could only switch between 1.5X and 6X, not variably adjust between them, but I can't remember where I read that... Hitman?
