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 platesolving (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 the default, for example, the model of the telescope and camera.
It is also worth setting the step size and the 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 “Platesolve” tab, you can set the default platesolve 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.

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 (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.

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, and 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. has 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 (ThreePointPolarAlignment) and an event reporting tool for the GroundStation sequencer.
Connection and operation
To turn on the AstroPC PRO II, 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 tim,e the green LED of the AstroPC PRO II panel should light up. The power-on and boot process takes approximately 30 seconds. After that, AstroPC PRO II is ready to work and now you can connect to a remote working AstroPC PRO II. 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.
Below, for example, are screenshots of using AstroPC PRO II with a SkyWatcher equatorial mount, Canon 600D SLR camera, and ASI120MMMini guide camera. The following applications and drivers are used to work with this equipment:
- Planetrium Cartes du Ciel (“CDC” , “SkyChart”)
- ASCOM 6.5SP1 platform
- EQmod for Sky-Watcher and Orion Mounts ASCOM telescope driver
- AWO ASI Camera Driver
- Canon EOS Utility Software
- PHD2 telescope guiding software
- N.I.N.A. astrophotography automation software
An Android smartphone is used to connect to the remote desktop.
