N.I.N.A. Application

N.I.N.A. is an all-in-one system that can combine all your astronomical equipment and processes into one easy-to-manage system. It is an astronomical processor that allows you to control the full range of astronomical equipment from mounts, cameras, and focusers to observatory domes.
The N.I.N.A. application provides a full cycle of operations for astrophoto graphic observations. During the shooting of N.I.N.A., it can recognize stars in images and track the quality of images by the size of star images (Half Flux Radius).

Basic Setup for N.I.N.A.

1. Install N.I.N.A. from a USB flash drive.
2. Go to the Settings tab and set the most important basic settings such as telescope parameters (equipment tab) and observation site coordinates (General tab).
3. Specify the name of the profile instead of default, for example, the model of the telescope and camera.
4. Set the step size and focuser backlash in the Autofocus section.
5. If the telescope is installed in a dome, set the basic dome settings in the Dome tab.
6. In the Shooting tab of the program settings, set the format, template and paths for recording files, the parameters for meridian flip, and the parameters of the visible image.
7. In the Plate solve tab, set the default plate solve program.

Sky Atlas

To prepare a program of upcoming observations and quickly walk through the objects, a handy sky atlas is built into the program. Objects in the atlas can be selected by a number of characteristics such as constellation, size, brightness, minimum height above the horizon, or simply by catalog name. In the Sky Atlas, to the right of each object, a graph of its visibility is displayed, taking into account the dark time of the day for planning the time of its observations. On the left in the atlas window, information about the current visibility conditions (moon phases, start and end times of astronomical twilight) is always visible. From the atlas window, you can quickly aim at the selected object, add it as a target for the series, or transfer its coordinates to the crop window.Instructions for using these applications and drivers are available on the developer’s websites. In addition to these applications, you can install any other application easily and simply. The  best way to do this is to install the application from a USB flash drive.
Please take a look at the N.I.N.A.
N.I.N.A is an all-in-one system that can combine all your astronomical equipment and processes into one easy-to-manage system!
The N.I.N.A application is used to automate the processes of controlling astronomical equipment and astrophotography. N.I.N.A is an astronomical processor with great  capabilities. N.I.N.A. allows you to control the full range of astronomical equipment – from  mounts, cameras and focusers, to observatory domes.

A brief overview of the features of the N.I.N.A.

Application N.I.N.A. provides a full cycle of operations for astrophotographic observations:

• search for a subject in a convenient built-in atlas and framing
• turn on/off the equipment and align the polar axis
•  pointing the telescope at the object and plate solving (pointing refinement)
•  interaction with the guide program (PHD Guiding) to control guiding and dithering and dome tracking of the telescope,
• meridian flip
• camera cooling, camera and filter wheel control while shooting an object
•  automatic focusing and refocusing when external conditions change
•  Parking of the telescope at the end of observations.

During the shooting of N.I.N.A. can recognize stars in images and track the quality of images by the size of star images (HalfFluxRadius).

Basic setup
After installing the N.I.N.A., first of all, you should go to the “Settings” tab and set the most important basic settings, such as telescope parameters (“equipment” tab) and observation site  coordinates (“General” tab), which can be taken from the configured program of the Cartes  du Ciel planetarium.  It is worth specifying the name of the profile instead of default, for example, the model of the  telescope and camera.  It is also worth setting the step size and focuser backlash in the “Autofocus” section. If the  telescope is installed in a dome, it is worth setting the basic dome settings in the “Dome” tab.  In the “Shooting” tab of the program settings, you can set the format, template and paths for  recording files, the parameters for meridian flip, the parameters of the visible image (so that it  is not too bright in the shooting window when auto image brightness stretching is enabled),  In the “Plate solve” tab, you can set the default plate solve program.

Hardware setup

The next step, after the basic setup of the program, you can configure the astrophoto equipment in the main tab “Equipment”.  First, set up the camera in the “Camera” tab (hardware drivers must be installed in advance).  Select the desired camera from the list of installed ones, configure its parameters in the  settings window (the “Settings” button to the right of the list of cameras) and you can turn it  on with the “Enable” button on the right.  Next, in a similar way, you need to select and connect all the installed equipment – the  focuser, the filter wheel, the telescope (mount). In the “Guide” section, you can connect to  the external autoguiding program PHD Guiding, which must be installed, enabled and  configured in advance. Interaction N.I.N.A. with PHD Guiding allows you to visually display  the guiding graph in the program’s shooting window and stop / start guiding when dithering.
Shooting window
You can shoot frame-by-frame and control the continuous shooting process in the “Shooting” window. On the Image tab, you see the results of the survey, the Guide panel with the guiding  schedule, and the Shooting panel with manual frame-by-frame controls. The Image panel has  tabs and buttons for manual and automatic focusing, platesolving. Here you can see in the  loop shooting mode how the telescope is pointed at the object, correct the aiming and  focusing, monitor the quality of the received images, and align the polar axis.

Useful Tools

In addition to impressive base features N.I.N.A., there are many additional tools that greatly simplify the observation process. These include the Polar Axis Alignment Assist plug-in, the Bakhtinov mask focus assistant, a panel for quickly navigating through a list of bright stars to focus on, and a powerful assistant to automatically capture optimal flat field shots.
The list of instruments will be updated as the program has, in addition to open source, an API for creating plugins – third-party extensions. At the moment, 6 useful plugins have already been created, including a polar axis alignment helper (Three Point Polar Alignment) and an event reporting tool for the Ground Station sequencer.

Connection and operation

To turn on the AstroPC PRO, you need to connect a 12V power supply to the power input connector. After that, you need to press the power button and at the same time the green LED of the AstroPC PRO panel should light up. The power on and boot process takes approximately 30 seconds. After that AstroPC PRO is ready to work and now you can connect to a remote working AstroPC PRO. To do this, you need to detect the AstroPC WiFi network (SSID “AstroPC”), and connect to it from your device. Then, using the Microsoft Remote Desktop client application, you can connect to the AstroPC remote desktop using the following parameters: Computer name – AstroPC, UserName – AstroPC, password – empty.
