ESATTO 3.5" LP (Low Profile) from PrimaLuceLab: Robotic Microfocuser

PrimaLuceLab's ESATTO 3.5" LP (Low Profile) is a robotic microfocuser designed for astrophotographic setups requiring low backfocus. With a thickness of just 32 mm, it combines extreme precision, impressive load capacity and extensive compatibility, making it an essential tool for fast astrographs and telescopes with limited backfocus.

Advanced technical features

  • Exceptional precision: Resolution of 0.01 microns per step, offering ultra-fine adjustment for perfectly sharp images.
  • Load capacity : Supports up to 10 kg, ideal for cooled cameras, filter wheels and heavy accessories.
  • Focal length : 10 mm, allowing precise adjustments in complex optical systems.
  • Open to the public : Internal diameter of 90 mm, optimized for large-format sensors and wide-field instruments.

Optimized backfocus

  • Minimum optical thickness : Only 32 mm, making it one of the slimmest focusers on the market. This design is ideal for telescopes with limited backfocus, such as fast astrographs.
  • Its thinness makes it easy to integrate the focuser in configurations where every millimeter counts, while maintaining optimum mechanical stability.

Mechanical interfaces

Input interface (telescope side) :

  • The ESATTO 3.5" LP uses a customizable interface with specific adapters available to fit a wide range of telescopes, such as refractors, Newtonians or astrographs. If no standard adapter is suitable, PrimaLuceLab offers a custom manufacturing service.

Output interface (accessory side) :

  • Standard M98x1 female thread for direct connection of DSLR/mirrorless or CCD/CMOS cooled cameras.
  • Optional adapters with clamping rings allow the camera to be locked at a precise angle for optimum framing.
  • Native integration with ARCO 3" rotator, enabling field rotation or derotation without additional cables.

Connectivity and control

  • Robust USB-C port : Allows reliable connection to a Windows PC or EAGLE system. Power and control via a single cable.
  • Integrated WiFi : Wireless control via the Virtual HandPad app on smartphone, tablet or computer.
  • Compatible software : Works with PLAY software and ASCOM drivers, enabling centralized, automated management.

Robust, versatile design

  • Made from high-quality materials to guarantee durability and lightness (total weight: 1150 g).
  • Equipped with a temperature sensor port, to automatically adjust focus according to night-time temperature variations.
  • Dimmable LED to avoid light pollution during observation.

In the Box

  • ESATTO 3.5" LP microfocuser
  • A robust USB-C cable
  • Detailed user manual

Specific adapters (telescope or camera) are available separately to meet the particular needs of your configuration.

Distinctive features

  • Ultra-thin profile (32 mm thick), perfect for telescopes with low backfocus.
  • Exceptional micrometric resolution (0.01 micron/step).
  • Heavy-duty payload (10 kg) with 90 mm free opening.
  • Flexible mechanical interfaces: M98x1 female thread on the camera side and customizable adapters on the telescope side.
  • Advanced integration via USB-C, WiFi and ARCO compatibility.

Conclusion

The ESATTO 3.5" LP is the ideal solution for maximizing the performance of instruments requiring low backfocus, while offering unrivalled precision and maximum flexibility for your advanced astrophotography projects.
