Starry Night Pro Plus 9: The Definitive Guide to the Ultimate Astrophotography and Astronomy Software For amateur astronomers, educators, and seasoned astrophysicists alike, the software you choose is the lens through which you view the cosmos. While mobile apps like SkyView or Stellarium offer quick glances at the night sky, professionals demand precision, data depth, and simulation accuracy. Enter Starry Night Pro Plus 9 —the newest iteration of what many consider the "Cadillac" of desktop planetarium software. But is it worth the hefty price tag and steep learning curve? In this deep-dive review, we will explore every nebula, spacecraft trajectory, and telescope control feature of Starry Night Pro Plus 9 to help you decide if this is the right observatory companion for you. What is Starry Night Pro Plus 9? Starry Night Pro Plus 9 is the flagship product from Simulation Curriculum Corp. Unlike basic planetarium software that shows stars as static dots, Pro Plus 9 is a dynamic, physics-based 3D simulation of the known universe. The "Pro Plus" distinction is critical: It includes every feature of the standard "Pro" version, but adds professional-grade database expansions, advanced telescope control, and access to 3D models of spacecraft and cometary orbits. This version represents the ninth major iteration of the software, building on two decades of refinement. It is designed not just for looking at the sky, but for interacting with it. You can travel to the surface of Europa, simulate the impact of an asteroid, or plan a year’s worth of astrophotography sessions from your living room. Key Features That Set Version 9 Apart 1. The Deep-Sky Database: Beyond NGC and IC The standard version of Starry Night comes with a solid database of 700,000 stars. Starry Night Pro Plus 9 ups the ante dramatically. It includes the USNO-A2.0 catalog, which contains over 500 million stars, and the Hipparcos catalog with precise astrometric data. More importantly for deep-sky enthusiasts, it integrates the Principal Galaxies Catalogue (PGC) and the Lyon-Meudon Extragalactic Database (LEDA) , allowing you to zoom into galaxies millions of light-years away and resolve individual globular clusters within them. 2. The All-New 3D Spacecraft Engine One of the most celebrated updates in Starry Night Pro Plus 9 is the enhanced 3D spacecraft engine. You can now watch a real-time, textured 3D rendering of the James Webb Space Telescope (JWST) unfolding at L2 Lagrange point, or track Voyager 1 and 2 with their exact trajectory paths derived from NASA JPL data. You can even ride along with these probes, viewing the sky from their perspective—a feature invaluable for mission planning or science communication. 3. Unmatched Telescope Control (ASCOM & INDI) For astrophotographers, the "Plus" in the name means precision. Version 9 supports ASCOM (Windows) and INDI (Mac/Linux) protocols natively. Unlike free software that sometimes loses connection during a meridian flip, Starry Night Pro Plus 9 features "DirectX 3D rendering" that reduces latency. You can create custom observing lists, sync your goto mount to an off-axis guide star, and even automate imaging sequences by scripting dome rotations to follow a moving object like a near-Earth asteroid. 4. Realistic Atmospheric and Light Pollution Modeling One of the software's party tricks is its atmospheric engine. You can enter your exact GPS coordinates and set the "SQM" (Sky Quality Meter) reading for your backyard. Starry Night Pro Plus 9 will render the sky exactly as it looks through your eyepiece—including the effect of a rising moon on contrast, twilight gradients, and even the glow of aurora borealis. Who Is Starry Night Pro Plus 9 For? The Astrophotographer If you own a Paramount or Sky-Watcher mount, you need precise polar alignment tools. Pro Plus 9 includes a "Polar Alignment Tool" that uses plate-solving to tell you exactly how far off your polar axis is. It also features a Field of View (FOV) indicator —you can enter your specific scope and camera (e.g., a Celestron EdgeHD 11" with a ZWO ASI2600) and see exactly what your sensor will capture. The Science Educator For university-level astronomy labs, this software is a game-changer. You can turn off artificial light pollution and travel to a dark sky site in Chile instantly. The "Time Flow" control allows you to show students the precession of the equinoxes over 26,000 years or the proper motion of Barnard’s Star over a human lifetime. The Advanced Amateur You are no longer satisfied with "big dipper" tours. You want to observe colliding galaxies or variable stars. Starry Night Pro Plus 9 includes light curve prediction for thousands of variable stars, synced with the AAVSO (American Association of Variable Star Observers) database. You can literally see a star dimming in real-time simulation. Performance and System Requirements (The Fine Print) Before you purchase, note that Starry Night Pro Plus 9 is a resource hog. To run the 500-million-star database smoothly, you need:
OS: Windows 10/11 or macOS 11+ RAM: 8 GB minimum (16 GB recommended) GPU: Dedicated graphics card with 4GB VRAM (Integrated Intel graphics will struggle with 3D spacecraft mode) Storage: 20 GB for full installation (the high-resolution texture maps take up considerable space)
The software occasionally suffers from "time drag" when you fast-forward time through the year 9999 AD, but for realistic human timescales, performance is fluid on modern gaming-class hardware. How Does It Compare to the Competition? It is impossible to write a review of Starry Night Pro Plus 9 without comparing it to Stellarium (free) and SkySafari 7 Pro (mobile).
vs. Stellarium: Stellarium is prettier out of the box. Its open-source rendering engine is gorgeous. However, Stellarium lacks the deep telescope control and the historical/spacecraft ephemeris data. Pro Plus 9 wins for planning ; Stellarium wins for casual viewing . vs. SkySafari 7 Pro: SkySafari is portable (iPad/iPhone) and excellent for visual observing. But Starry Night Pro Plus 9 is a desktop workhorse. You cannot run a remote observatory with SkySafari; you can with Pro Plus 9 via its advanced scripting (JavaScript and Python support). Starry Night Pro Plus 9
The Pros and Cons Pros:
Database size: 500 million stars means you will never run out of targets. Historical accuracy: Simulate the sky from 99,999 BC to 99,999 AD with correct planetary positions. Visual realism: The new volumetric nebulae rendering makes the Orion Nebula look photographic. Support: Frequent patches and a dedicated user forum for troubleshooting driver issues.
Cons:
Price: At roughly $150-$200 USD, it is expensive compared to free alternatives. Learning Curve: The interface is cluttered. Finding the "observing list" option vs. the "image pipeline" takes time. Mobile Sync: Unlike Starry Night's cheaper versions, Pro Plus 9 does not easily sync observations to a mobile phone companion app.
Setting Up Your First Session: A Quick Guide Let’s walk through a typical use case. You want to photograph the Helix Nebula (NGC 7293).
Location: Enter your exact latitude/longitude or let the software detect your IP location. Equipment: Go to "Setup" > "Telescope" > "ASCOM." Select your mount driver. Enter your scope's focal length (e.g., 1000mm) and camera sensor size. The Search: Type "NGC 7293." The software slews the view. The Plan: Use the "Altitude vs. Time" graph. You see the nebula peaks at 65° altitude at 2:00 AM next Saturday. The moon is waning crescent—perfect. The Capture: Right-click the target and select "Start Imaging Sequence." Starry Night Pro Plus 9 will generate a script that tells your mount to center the nebula, wait for guiding to settle, and take 60x300 second exposures. Post-processing: You export the .FITS file headers for use in PixInsight. Starry Night Pro Plus 9: The Definitive Guide
The Verdict: Is It Worth It? Starry Night Pro Plus 9 is not a product for everyone. If you are a casual observer who steps outside twice a month, buy a pair of binoculars and download Stellarium. You will be happy. However, if you own a permanent pier, a $5,000 imaging rig, or teach astrophysics, Starry Night Pro Plus 9 is the final piece of the puzzle. It is the difference between guessing where an exoplanet transit will occur and predicting it to the second. The ability to control your dome, mount, and camera from a single unified timeline interface removes the friction from astrophotography. Final Thoughts As light pollution worsens and we rely more on screens to find the deep sky, software like Starry Night Pro Plus 9 becomes a necessity rather than a luxury. Version 9 successfully bridges the gap between "cool space visuals" and "legitimate research tool." The spacecraft database alone—allowing you to virtually fly past Pluto with New Horizons—offers an emotional resonance that free software rarely achieves. If you have the budget and the hardware, buy it. Your rig will spend less time slewing and more time imaging. And in astrophotography, time is the only commodity that truly matters.
