  • PST Micro Tracker

    The PST Micro Tracker packs a 3 kg (6.6 lbs) payload capacity into a CNC-machined all-metal body that weighs a mere 390 gm. Its internal Li-Poly battery provides up to 10 hours of silent tracking for capturing sharp, long-exposure images of the night sky, and the entire unit measures a compact 76x63x56 mm for ultimate portability on any adventure.

    3 kg Payload Capacity with a Worm Gear Drive

    Despite its minimal footprint, the PST Micro Tracker supports camera and lens combinations up to 3 kg (6.6 lbs), making it ideal for most mirrorless or DSLR wide-field setups. The internal worm/gear system ensures smooth, consistent tracking to prevent star trails in your images. Four tracking speeds (Solar, Lunar, full-speed 1X Celestial, and 1/2X Celestial) allow you to follow any target or create stunning nightscapes where both the stars and foreground remain sharp.

    Ultra-Portable at 390 g with a 10-Hour Internal Battery

    Engineered for the traveling astrophotographer, the tracker's 390 gm weight and compact 76x63x56 mm body make it virtually unnoticeable in a camera bag. The integrated Li-Poly battery delivers up to 10 hours of continuous operation on a full charge. For extended sessions or multi-night trips, the mount can be powered or recharged in the field via its USB Type-C port from any standard 5V power bank.

    Flexible Mounting with a Vixen Base and 3/8"-16 Threads

    The PST Micro Tracker is designed for universal compatibility. Its base features a Vixen-style dovetail bar with both 3/8”-16 and 1/4”-20 threaded sockets, allowing it to mount securely to any photo tripod or astronomical mount. A Ø48 mm mounting block with a 3/8”-16 post accepts a wide range of camera ball heads for easy framing. For precise polar alignment, the tracker is compatible with optional accessories like an EQ base and either an iPolar or AccuAlign polar scope.

    PST Micro Tracker vs. Larger Trackers: The 390g Portability Advantage

    While larger star trackers may offer higher payload capacities, they often weigh several times more than the PST Micro Tracker's 390 gm. This makes the Micro Tracker the superior choice for situations where every gram counts, such as airline travel, backpacking, or hiking to remote dark-sky sites. You get the core functionality needed for high-quality wide-field astrophotography without the bulk and weight of a traditional equatorial platform.

  • What kind of camera setup can the PST Micro Tracker handle with its 3kg payload?

    The 3 kg (6.6 lbs) payload capacity of the PST Micro Tracker is sufficient for most DSLR or mirrorless cameras equipped with wide-angle to short-telephoto lenses (e.g., 14mm up to 200mm). Always include the weight of the ball head when calculating your total payload.

    How do I polar align the PST Micro Tracker?

    The PST Micro Tracker requires an optional equatorial base and a polar scope for accurate alignment. You can use either the optional iPolar electronic polar scope for a fast, precise digital alignment or a traditional illuminated AccuAlign optical polar scope. Without these, only very short exposures with wide lenses are possible.

    What is the 1/2X tracking speed on the PST Micro Tracker used for?

    The 1/2X Celestial speed tracks the stars at half their normal rate. This is a specialized mode for nightscape photography where you want to capture both a detailed starry sky and a sharp landscape in a single exposure. It splits the difference in apparent motion, reducing star trailing while also minimizing foreground blur.

    Can I use the PST Micro Tracker to image the Andromeda Galaxy (M31) with a 200mm lens?

    Yes, provided your total camera, lens, and ball head weight is under the 3 kg payload limit. A 200mm lens is approaching the practical limit for a tracker of this size, so a very precise polar alignment using an optional iPolar or AccuAlign scope will be critical to achieving sharp, untrailed stars in exposures longer than 30-60 seconds.

    I'm hiking to a dark sky site. How does the PST Micro Tracker's power system support multi-night imaging?

    The PST Micro Tracker is ideal for this scenario. Its internal battery lasts for up to 10 hours, covering a full night of imaging. For subsequent nights, you can recharge it during the day or run it continuously from a small, portable 5V USB power bank via the USB-C port, ensuring you never run out of power.

    Can I use the PST Micro Tracker in the Southern Hemisphere?

    Yes. The PST Micro Tracker has a North/South (N/S) switch that reverses the motor direction, making it fully functional for astrophotography in both the Northern and Southern Hemispheres.
