[QUOTE=Antar;1554693]1) For polar star the latitude should be = sextant meter.
For sun it should be 90-sextant meter.

(At north pole the polar star should be 90, sun 0)

But... looking on your screen I'm not sure that "0" at sextant meter is on horizon. It looks like "0" is at bottom on screen...

The "0" is always at bottom of screen--so I just look up until 0 is lined up with horizon. Is there another way to move/scroll the sextant?

[QUOTE=brandtryan;1554716]put your mouse in the middle of it (on the tape), left click and hold and move to new position. Click on the sextant image to rotate horizontally/vertically

[QUOTE=TheDarkWraith;1554717] thanks!

To be at all accurate it needs to be able to measure at least to within 0.1 of a degree. ideally even more precision is required - 0.01

It would obviously need an optic zoom function to achieve this, although having to maintain the horizon in view would further limit the observable altitude.

So, aswell as a optic function, a vertical moving scale that indicates the angle (of your eye as it were) in degrees is also needed - this would negate the need to keep the horizon in view.

The vertical scale could work like the stadimeter, only returning the angle instead of calculating range with it. Any idea if this is possible?

When game start (3 IX 1939, Kiel, little cloud) I check the latitude at 55° N at midnight.

In my opinion the polar star should be visible at 55°, but it was at 72°...
:doh:

But wait a moment... there are different resolution of game. All menus are in this same resolution, with the sextant scale. Only "view" is represented in higher or smaller area.
Now I check latitude for:
1280x1024 (my default) - polar star was at 72° - ab UMa dist - 94.03px
1024x768 (windowed) - polar star was at 53° - ab UMa dist - 65.10px
In real - 55°

BTW. because the scale was too small ta catch the polar star or catch the horizon line and polar star at the same time I used screenshots and put the sextant scale to screenshot with stars. So is possible that my conclusions are incorrect.

@TDW:
NAV order bar does not work with 5.7.0.

I don't know why your nav order bar doesn't work. I can't duplicate the problem no matter what I try. Have you tried disabling all mods except the core UIs mod and seeing if you still have the problem? :hmmm:

Have an idea on how we can make the sextant accurate. Instead of the sextant tape as it is now I could make it a small, thin line across the screen. You 'zero' the line with the horizon then move it up until it's centered on the item you want the reading for (if you use external camera then the horizon will be stable). As you move it up and down I show you the angle in degrees. If we think of it as a triangle (viewed from side):


z (line on screen)
|
|
|___________________________________x (viewer position)
fixed length y

The angle I'd be displaying is tan-1(z distance/ fixed length y). The only variable is z distance and that is changed by moving the line up and down on the screen. We make the fixed length y a value of 250 (meaning 250 pixels). z distance would be measured in screen pixels. In essence this would be like using the real sextant :DL Or am I totally hosed in my thinking here :06:

You are genius - you gave me extra idea (obs periscope used):

:D

not following you here. Are you saying to use my line idea :06:

It is not a bad idea with the line...

I wrote before that ideally we should have a stadimeter with high zoom (modded UZO, for example), with stabilized view (just look at the deck gun always stabilized at horizont) and with the ability to tilt stadimeter ghost picture up to 90 degrees (up to the zenith). I.e. you will have two pictures on the same screen, one of those pictures is stabilized with horizont in the middle and the other can be tilted up up to 90 degrees. Precise tilt angle and bearing should be indicated as well. Then all that you will need to do is make the sun lower limb in the ghost picture touch the horizon in the 'real' picture at 12:00PM and take angle and bearing readings. Then you just look up those numbers in tables and you're done basically. And that will be full simultation of sextant and readings taking.

As you see on the screenshot I used the observation periscope.

So is possible find horizontal line by periscope... and the polar star too.
But question is how to read angle between these two views of periscope.

I think that is possible. If you have "bearing scale" in periscope eye maybe is possible put the "angle scale" ?
This works similar to stadimeter: 1st line (periscope head) and 2nd line (periscope head). After that read the angle with six points accuracy.

The big problem I have is I can't hold and use one (Sextant). It's hard to model something you don't understand and can't use to see how it works.
I won't be able to do a split image. The best I can do is the current tape or a line on the screen that you move up and down. It seems like screen resolution would play a part in the line one but I'm not grasping how....or would it? :hmmm:

Tried this does not have any affect also seems now there are others folks meeting up with the same problem refer to the following

When firing deckgun at night, explosions have "box" graphics

TWD please can you take a look into this

R

I don't do anything with event graphics (particles). I'm strictly 2D with the UIs mod. It's more than likely the environment mod or some other mod causing the problem. Any mod that modifies the particles.dat file, materials.dat file, or includes new .dds files located in \data\Textures\TNormal\tex are suspect.

For the Sextant you need the zoom and precision of the obs or uzo scope.
But you dont need a split screen or double image.

If you can click the horizontal scope line on horizon to start reading the angle and then tilt up to north star and click again. Read the angle.

what is the max angle we'd be looking for? I think I just had a euraka moment :rock:

EDIT: eueka moment shattered :wah: I thought the solution box could be the answer:

I was thinking about grabbing the angle (marks) but it's not correct (angle too small). Though it does make me think that there is a game dial associated with this. It has to be getting and determining the angle from some kind of dial (hopefully) :hmmm:
