The OG Star Tracker V2 is a 3 lb, portable tracker with 10″-15″ precision, laser/polar alignment, modular upgrades, app control, and a quiet stepper motor. Our OG Star Tracker V2 review explores the power bank it runs on, how it supports dithering, and suits all skill levels, offering pro results with easy setup.
Astrophotography is as much about the gear as it is about the passion for the cosmos. Over the years, tracking mounts have evolved, and the OG Star Tracker V2 Fully Build represents one of the latest products designed to make astrophotography as seamless as possible. For those of us who dream of long-exposure images of star trails, nebulae, and distant galaxies, having a reliable and accurate tracker is a game-changer.
OG star tracker V2 review
The OG Star Tracker V2 comes as a fully built unit, meaning that, right out of the box, you can set it up and start tracking the stars without having to assemble a complex kit. With shipping slated to start at the end of March, this product has already garnered interest for its promise of portability, precision, and customization.
- Weighing in at just 3 lbs, this tracker is designed for portability. For those of us who often travel to remote locations for darker skies, every gram counts. A lightweight design means less strain when trekking to an ideal stargazing spot, yet it doesn’t compromise on stability.
- One of the most exciting specs is its periodic error of only 10″ - 15″. In astrophotography, where even the slightest deviation can blur long-exposure images, this level of precision is critical. It promises the potential to capture long exposures without the need for an auto guider, a feature that can simplify your setup immensely.
- The tracker isn’t a one-size-fits-all solution. Its design allows for customization, swap between a laser and a polar scope, add a ball head, or even upgrade with a manual declination axis. This adaptability means that whether you’re a beginner or a seasoned astrophotographer, you can tailor the tracker to suit your specific needs.
- Traditional polar alignment can be a bit of a challenge, especially when you’re working with limited visibility or under pressure. The OG Star Tracker V2 simplifies this process by offering an easy alignment method: simply aim the laser at Polaris. This innovation is a welcome relief for those who prefer quick setups and minimal hassle.
- For those who love to fine-tune every aspect of their astrophotography, the built-in intervalometer port with dithering support is a huge plus. Dithering is essential for reducing noise in your final image, and having it integrated means one less accessory to worry about.
The tracker uses a high-accuracy 0.9° stepper motor paired with a TMC2209 driver. The TMC2209 is known for its silent operation and precision control, which is essential when you’re in a dark, quiet field trying not to disturb the delicate balance of your setup. This ensures that every slight movement is calculated and smooth, contributing to the overall accuracy of the tracker.
You have the flexibility to control the tracker via an app or a phone web app, providing a modern, user-friendly interface that can be operated remotely. It runs on a modest 5V 1A power bank, which is both convenient and accessible. This means you can keep your setup running even in locations where power outlets are scarce.
Constructed from ABS-GF and ABS, the tracker is both durable and lightweight. These materials are commonly used in high-quality consumer electronics, balancing the need for resilience in the field with the benefit of a lighter overall weight.
You can choose between “Polar scope” and “Laser” methods for alignment. For those who prefer traditional methods, the polar scope option remains available. However, the laser alignment is particularly innovative, streamlining the setup process and minimizing potential alignment errors. The tracker offers options to set for different latitude ranges, “90°-25°” and “25°-0°”. This is crucial for ensuring accurate tracking regardless of your geographic location, making it a versatile tool for astronomers around the globe.
One of the standout features of the OG Star Tracker V2 is its modularity. As an amateur astrophotographer, I often find that the ability to adapt and customize your gear is invaluable. Not everyone’s needs are the same, while a novice might be thrilled with a simple setup, an advanced user may want additional control over declination or the ability to add a ball head for more versatile mounting.
The option to swap between laser and polar scope alignment methods means that you’re not locked into one particular workflow. Traditionalists might prefer the polar scope for its tried-and-true method of alignment, while others may embrace the quick and intuitive laser alignment. This kind of flexibility ensures that the tracker can evolve with your skills and requirements over time.
Comparing the OG Star Tracker V2 with other products
Many entry-level trackers struggle with periodic error, often requiring an auto guider to compensate. With an error margin as low as 10″ - 15″, the OG Star Tracker V2 stands out as a promising tool for those aiming to capture detailed, long-exposure astrophotography without additional equipment.
Other trackers in a similar price range may not offer the same level of customization or the innovative alignment options that the OG Star Tracker V2 provides. The modularity, combined with advanced features like the built-in intervalometer port with dithering support, positions this product as a strong contender for those who want professional-level results without the complexity that usually comes with high-end astrophotography gear.
The low periodic error is a boon for long-exposure photography. This means you could potentially capture the intricate details of star trails, the Milky Way, or even faint deep-sky objects without the blurring that comes from tracking inaccuracies.
Given its lightweight design, this tracker is perfect for astrophotographers who travel. Whether it’s a weekend camping trip or a longer journey to a remote dark sky location, the ease of transport and setup can make a significant difference in your overall experience.
The ability to adjust and upgrade the tracker means it can be as basic or as advanced as your astrophotography style demands. For beginners, the simple laser alignment can reduce the learning curve, while experienced users can tweak the setup to achieve optimal performance for their specific camera systems and lenses. With control options via a dedicated app or a phone web app, setting up and calibrating your tracker becomes a modern, streamlined process. The integrated control system minimizes the need for additional accessories, which is ideal when you’re setting up in the field under less-than-ideal conditions.
