The graticle in DGUI uses milliradians but the graticle in DGUI Hardcore uses angular radians (16 per degree instead of 17.45) as in real life. I even included real life tables that you can use to convert to distance.

there is no way to change the vignette when you change the zoom

Out of curiosity, I can't wait to see how "Crush Depth" will handle this.

I don't know which eyepieces were placed on the Uboote.
But I am almost convinced that the engineers of ZEISS, have placed "wide angle".
I use a terrestrial telescope to watch the birds, and I use an eyepiece of this type (for the same zoom level, the panorama can be seen better)
On our French forum, a member with a refracting telescope has also just confirmed his change from the inexpensive eyepiece to a wide-angle eyepiece.

Well, "wrong" is not subjective here since we're talking about a game of the simulation genre. The game is either "right" (historically accurate), or it is not.

The magnification I'm talking about in my table is only related to the field of view (the one restricted by the vignette effect, not the in-game FOV), it is not related to the player screen size. There is no way for the devs to control that (unless they add a slider in the setting screen for a kind of "magnifying glass" effect). About that 10x magnification in GWX, I don't see how it could have been computed given what I just said, but I agree that the bigger the ship on screen the better the gameplay: I did the math and found out that for the magnification to be optically accurate, I had to stand as close as 38 cm from my 27" display! And Wolfpack devs actually did an amazing job at that by having chosen to ditch the upper and lower parts of the image circle so it can appear bigger.

Considering your expressed concerns, I haven't found how those modifications would break any current gameplay mechanics. Did you have something specific in mind?

My comments were general nature, not at your examples. I'm of the opinion that "historically accurate" does not necessarily need, demand, nor require verbatim "historically accurate" figures, specs, etc. to be used, for "historically accurate" and "right" results to occur.

Your mileage may differ. :)

Well, if a model produces "right" results, by that very action it is then "right".
After all, that's the end result desired or should be. I.e., better to have that vs. a "right" model that produces "wrong" results.
But I understand what you're saying. Interesting work and effort you've done, thanks ! :salute:

In Sh3 it works like you say, there is a direct and inverse relationship between zoom and field of view. However, it is not like that in real life, it depends on the construction of the optical device.

In this particular case, the zoom ratio was 4 ( 1.5 to 6 ) but the field of view ratio was 4.22 ( 38 to 9 ). Since the graticle is just a 2d overlay it can't be accurate for both.

To give more examples, the field of view for the 7x50 binoculars was 7.1 but some 10x80 binoculars had a field of view of 7.25 even though they had 10x zoom. The field of view was different even between different models of the 10x80 binoculars.

What I did for DGUI was to use a 36 degree field of view for the low power, this way the periscopes can be calibrated at both magnifications. This is not historically accurate but I think it is more useful.
