Details will be described below.

[Processing means]
[Menu selection means]
When this application is activated, the menu selection means operates to display a selection screen for selecting one of “celestial bean knowledge”, “celestial object list”, and “astronomical event”.
If "Astronomical bean knowledge" is selected, the astronomical telescope guide that provides information such as the type of astronomical telescope and how to use the astronomical telescope, and the astronomical bean knowledge that provides information such as star movement and star type When the guide is displayed and the user selects a necessary item, the corresponding information is displayed.
When “Astronomy Events” is selected, a calendar of celestial events that allow you to enjoy celestial objects throughout the year is displayed. When the user selects an event in the astronomical event, information on the celestial object corresponding to the event is displayed.

[Object information display means]
The celestial information display means displays a list of selectable celestial bodies (object names) when “celestial object list” is selected by the menu selection means, and when a specific celestial object (object name) is selected from the list, Displays information about the object. Specifically, a diagram of the selected celestial body and related information about the celestial body are displayed.

[Authentication processing means]
The authentication processing means inputs an instruction to start astronomical telescope setting guidance (navigation for setting the astronomical telescope at the position of the celestial object) from the operation unit 14 for the celestial object selected and displayed by the astronomical information display means. And an authentication number input screen prompting the input of the authentication number is displayed.
Then, the authentication processing means determines whether or not the input authentication number is appropriate, and if it is appropriate, the navigation function can be used. The authentication process may be performed only at the first use, and once authenticated, it may be omitted thereafter.
The authentication number is printed, for example, in an instruction manual of the astronomical telescope.

[Operation screen display means]
The operation screen display means displays the operation screen of this application when authenticating that the correct authentication number has been input by the authentication processing means.
As the operation screen, a setting method, a direction adjustment method, a tilt adjustment method, and a compass correction method of the terminal 1 are described.
The compass correction method is used when the terminal 1 is correctly attached to the astronomical telescope, but the celestial object to be observed is not captured in the finder of the astronomical telescope even if this application is used. There may be a GPS error. In this case, select the North Star as the celestial object in this application, set the celestial telescope to the orientation and inclination of the North Star, and look into the finder to capture the North Star with the celestial telescope. When the compass correction button is pressed in this state, the current azimuth and inclination are corrected in this application. Compass correction may be performed with a celestial body instead of the North Star.

[Astronomy status display means]
The celestial body status display means displays the azimuth and inclination of the celestial body selected by the celestial information display means when “Start” is selected on the operation screen.
The celestial body status display means also displays information on celestial coordinates, observation points, and observation date and time at the bottom of the screen.
The celestial coordinates are the coordinates of the celestial object to be observed calculated by the astronomical orbit calculation based on the observation date information. Note that parameters and orbital calculation formulas for performing astronomical trajectory calculations for the celestial bodies in the celestial body list are stored in the storage unit 12.
The observation point is position information of the terminal 1 detected using a GPS receiver or the like.
The observation date and time is information on the current date and time acquired using a GPS receiver or the like.

The screen displayed by the celestial object status display means displays a first mark indicating a specific direction of the terminal 1, and a second mark indicating the orientation of the celestial body on a circle drawn inside the first mark. Is displayed.
That is, a double circle is drawn, the first mark is displayed in yellow just above the outer circle (above the front of the terminal 1), and the compass east, west, north and south ( E, W, S, N) are displayed, and the orientation of the celestial body is displayed in yellow as the second mark.

  In addition, two straight lines are drawn in the vertical direction (vertical direction) with respect to the front of the display screen, and the tilt of the celestial object is displayed as a third mark with a red circle therebetween. The upper side of the straight line is (-) and the lower side is (+), and the center position is a position that matches the inclination of the celestial body.

[Direction / tilt adjustment means]
The azimuth / tilt adjustment means moves (changes) the direction of the astronomical telescope (the direction of the terminal 1) with respect to the azimuth and inclination of the celestial object displayed by the astronomical condition display means, thereby azimuth and inclination of the astronomical telescope with respect to the celestial object. Can be adjusted.

Specifically, when the azimuth of the astronomical telescope is moved with respect to the first mark so that the second mark overlaps (the first mark and the second mark face the same direction), the astronomical telescope The azimuth of the astronomical telescope is almost the same as the celestial azimuth, and the tilt of the astronomical telescope is changed so that the third mark is positioned at the center of the straight line. It almost coincides with the slope.
Note that a sound is generated when the third mark falls within an appropriate range.

  Once the azimuth and tilt of the astronomical telescope have been adjusted by the azimuth / tilt adjustment means, confirm the position of the celestial object with a scope and fine-tune the direction of the astronomical telescope to easily set the astronomical telescope for the celestial object to be observed. There is an effect that can be done.

[Process flow of this application: Fig. 3]
The processing of this application will be described with reference to FIG. FIG. 3 is a processing flowchart according to the present application. Note that FIG. 3 shows processing after the celestial body list is selected by the menu selection means.
As shown in FIG. 3, when the celestial list is selected, the celestial information display means displays a list of selectable celestial lists (S1), and determines whether or not the celestial object is selected from the list (S2). If not selected (in the case of No), the process returns to step S1, and if selected (in the case of Yes), the celestial information of the selected celestial body is displayed (S3).

  Next, it is determined whether or not an instruction to start navigation of the celestial body has been input on the screen on which the celestial information is displayed (S4). ), If it is finished (in the case of Yes), the process is finished. If the process is not finished (No), the process returns to S3.

  If the navigation of the celestial body is started (in the case of Yes), the operation screen display means displays the operation screen (S6). If navigation is used for the first time (first time), authentication processing by the authentication processing means may be performed, and if authenticated, the operation screen display means may be activated.

  Thereafter, it is determined whether or not an operation start instruction is input on the operation screen (S7). If the operation is not started (No), the process returns to the process S6. When an instruction to start operation is input (in the case of Yes), the celestial body status display means displays the direction and inclination of the celestial body, and the azimuth / tilt adjustment means adjusts the azimuth (S8), and the inclination is adjusted. As a result (S9), the azimuth and inclination of the astronomical telescope almost coincide with the azimuth and inclination of the observation object.

[Direction adjustment display screen: Fig. 4]
Next, the orientation adjustment display screen will be described with reference to FIG. FIG. 4 is a diagram showing a display screen for orientation adjustment.
Before the orientation adjustment, the white belt-like portion of the outer circle (the first mark: the yellow belt-like portion in the actual display screen) is located directly above the front of the display screen, and usually the inner circle The white belt-like portion (second mark: yellow belt-like portion in the actual display screen) displayed above is in a direction that does not coincide with the first mark.
In FIG. 4, the direction of the astronomical telescope is adjusted to move the position of the second mark to the position of the first mark so that the direction of the astronomical telescope matches the direction of the astronomical object.

[Tilt adjustment display screen: Fig. 5]
Next, a display screen for tilt adjustment will be described with reference to FIG. FIG. 5 is a diagram showing a display screen for tilt adjustment.
In the state of FIG. 4, this time, by adjusting the tilt of the astronomical telescope, as shown in FIG. 5, a white glowing circle between the two straight lines (third mark: glows red on the actual display screen) (Circular shape) is moved to the center position, and the tilt of the astronomical telescope and the tilt of the celestial body are matched.

  When the third mark moves to the vicinity of the center position, a sound indicating that the tilt adjustment has been properly performed is generated. In particular, since astronomical observation is performed in a dark place, notification by sound is effective. The notification sound can be stopped by tapping the “Stop” button at the lower right of FIG.

[Direction / altitude correction]
The preparation work before using this application and the azimuth and altitude correction for properly using this application will be described in detail.
[Finder alignment]
If the orientation of the astronomical telescope body is different from the orientation of the viewfinder, it will be difficult to find the astronomical object.
Therefore, in the daytime, look for landmarks such as telegraph poles and the tops of building antennas, attach an eyepiece with a low magnification to the astronomical telescope, and move and fix the astronomical telescope so that the landmark can be seen in the center.

  Next, while looking through the viewfinder, adjust the orientation and angle of the viewfinder so that the mark is in the center of the viewfinder. If the same mark is visible in the center of the astronomical telescope body and the viewfinder, the viewfinder alignment is complete.

[Advance and altitude pre-correction: Fig. 6]
The compass correction method has been described above, but a more specific description will be given with reference to FIG. FIG. 6 is a diagram showing an azimuth / altitude correction screen.
Sensors such as an electronic compass built in a smartphone are subject to errors due to the surrounding environment and the heat of the smartphone body. The magnitude of the error varies depending on the model and ranges from several degrees to several tens of degrees. If the error is large, it is impossible to search for a celestial body.

Therefore, it is desirable to correct the error when using this application.
Specifically, it finds the North Star by looking at the constellations. Place the North Star in the field of view with the viewfinder of the astronomical telescope. When looking through the astronomical telescope, align the North Star so that it is in the center of the field of view. In this state, fix the astronomical telescope.

Select “Polaris” from the “Star” list on the celestial object list screen of this application (the celestial object list screen), and enter an instruction to start celestial navigation.
The celestial body status display means displays the direction (azimuth) and inclination of the celestial body (north star), but the azimuth and inclination may be shifted.
When the orientation is deviated, the first mark and the second mark are not coincident, and when the inclination is deviated, the third mark is not at the center position.

In this case, when the “compass” mark (compass correction button) at the upper right shown in FIGS. 4 and 5 is tapped, the correction of the electronic compass is started.
As shown in FIG. 6, the electronic compass correction screen stores the current error as a correction value when the “Correction with current direction and altitude” button is tapped, and the first mark and the second mark match. And the third mark is centered. During correction, the compass correction button lights red.

Here, the first mark indicates the direction of the astronomical telescope, the second mark indicates the direction (azimuth) of the astronomical object, and the second mark is referred to as “azimuth light”. It is adjusted to illuminate the mark.
The third mark indicates an inclination and is referred to as a “pointer” and is adjusted so as to be positioned at the center of the screen.

[Release correction]
To cancel the correction, tap the compass correction button on the electronic compass correction screen and tap the “Clear correction value” button to cancel the correction.
“Cancel” in the electronic compass correction screen simply cancels the screen and returns the celestial state display means to the screen displaying the azimuth and inclination of the celestial body.

  The magnitude of the error may change due to the use of the smartphone for a long time or changes in the surrounding magnetic environment. If the position of the celestial object becomes large while using this application, you should correct the electronic compass again. In this case, it is not necessary to perform alignment with the North Star, and correction may be performed based on a star other than the North Star, for example, a star being observed or a nearby star.

[Example of terminal case mounting on a telescope: Fig. 7]
Next, the terminal case and attachment of the terminal case to the telescope body will be described with reference to FIG. FIG. 7 is a diagram showing another example in which a terminal case is attached to the astronomical telescope. FIG. 7A is a diagram showing a part of the telescope tube, FIG. 7B is a diagram showing an outline of the terminal case, and FIG. 7C is a diagram showing the terminal case attached to the astronomical telescope. It is a figure which shows a state.

As shown in FIG. 7A, first, an alignment line 21 longer than the terminal case (terminal case) 3 is formed in the longitudinal direction of the cylinder 2 in the cylinder 2 of the main body of the astronomical telescope.
As shown in FIG. 7B, the terminal case 3 is formed with a window portion 32 made of a transparent member, and includes a band portion 31 attached to the cylinder 2, and a mark line 33 in the center longitudinal direction of the window portion 32. Is formed.

The mark line 33 is formed to extend not only to the window portion 32 but also to a frame portion surrounding the window portion 32, and can be aligned with the alignment line 21 of the cylinder 2.

And the terminal case 3 which accommodated this terminal 1 on the cylinder 2 is installed. The installation is fixed to the tube 2 with the band portion 31.
At the time of installation, the alignment line 21 and the mark line 33 are overlapped. Thereby, the direction of the terminal case 3 can be correctly aligned with the direction of the astronomical telescope.

  Further, in a state where the terminal 1 is correctly stored in the terminal case 3, especially on a screen displaying the azimuth and inclination of the celestial body, the movement of the pointer indicating the inclination overlaps or is parallel to the mark line 33. It is easy to set the correct position of the terminal 1.

Therefore, if the terminal 1 is set so that the movement of the pointer on the screen displaying the azimuth and inclination of the celestial body is parallel to the mark line 33 of the terminal case 3, the direction (azimuth) between the terminal 1 and the terminal case 3 is set. Can be matched.
Furthermore, if the mark line 31 of the terminal case 3 is aligned with the alignment line 21 of the tube 2 of the astronomical telescope, the directions of the terminal case 3 and the astronomical telescope can be matched.
As a result, the direction of the terminal 1 and the direction of the astronomical telescope can be correctly matched.

The terminal case 3 may be formed only on the window 32 without forming the mark line 33 on the frame, or formed only on the frame without forming the mark 33 on the window 32. May be.
When the mark line is formed only on the frame part, it may be formed on both the upper and lower sides of the frame part, or may be formed on either the upper or lower side.
Further, the mark line 33 formed on the window portion 32 or the frame portion is not limited to a colored line, and may be a concavo-convex shape line that can be identified.
