There are a number of free astronomy software products. NINA (Nighttime Imaging ‘N’ Astronomy) is free, open-source astrophotography software designed to help amateur astronomers and astrophotographers capture and analyze astronomical images. Most every aspect of capturing astronomical images can be controlled and even automated by N.I.N.A.
Currently N.I.N.A is only available for Windows operating system. The software is comprised of several modules, including:
• Equipment Control: This module allows you to control your telescope, camera, and other equipment needed for astrophotography. Virtually any equipment that responds to ASCOM standard commands can be controlled.
• Imaging: This module provides tools for capturing complex imaging sequences, including autofocus, framing, and controlling filter wheels.
• Guiding: This module offers guiding tools for precise tracking of objects during long exposures.
• Plate Solving: This module enables you to identify and locate objects in the sky using image analysis algorithms. The module has a framing assistant that can pull images from internet sources to allow the perfect image composition. It will even skew the telescope to the precise chosen spot if the image does not exactly match the desired framing.
N.I.N.A also offers a user-friendly interface that allows users to customize their workflow and automate repetitive tasks. Additionally, the software includes support for several popular astrophotography hardware devices and protocols, such as ASCOM and the most popular guiding software PHD2. From the N.I.N.A website, the software has the following features:

I have been using N.I.N.A for several years now, and it just keeps getting better and better. With the addition of advanced sequencing, customization of a night’s worth of imaging makes it possible to image the entire night with little or no intervention. The learning curve is a bit steep, but there are plenty of helpful instructional videos available on YouTube. Once you get comfortable with the interface, N.I.N.A. is simply excellent.
Overall, N.I.N.A is a powerful and versatile tool for amateur astrophotographers and astronomers, providing them with all the necessary tools for capturing and analyzing astronomical images to achieve a nearly total automation process.
