  • PrimaLuceLab Adapter ESATTO 2" for Borg 55FL f/3.6

    The PrimaLuceLab Adapter for ESATTO 2" creates a dedicated, secure threaded interface for attaching the robotic focuser directly to the Borg 55FL f/3.6 astrograph, enabling precise and repeatable automated focusing for this premium, wide-field instrument.

    Seamless ESATTO 2" Integration for the Borg 55FL f/3.6

    This adapter allows you to upgrade the exceptional optics of the Borg 55FL f/3.6 astrograph with the advanced capabilities of the ESATTO 2" robotic focuser. By creating a solid, direct-thread connection, it fully integrates the telescope into the PrimaLuceLab ecosystem, allowing you to control focus remotely using PLAY software and take advantage of features like automated focusing routines and temperature compensation.

    A Zero-Flexure Connection for f/3.6 Imaging

    An extremely fast optical system like the f/3.6 Borg 55FL has a razor-thin critical focus zone where any amount of tilt or flexure can ruin an image, causing elongated stars at the edges of the field. This adapter replaces less secure connections, like compression rings or set screws, with a rigid, threaded interface that eliminates a primary source of imaging train tilt.

    For demanding astrophotography applications, this robust mechanical connection is essential. It ensures your camera sensor remains perfectly orthogonal to the optical axis, preserving the flat-field, pinpoint star performance the Borg 55FL is known for, even during long exposures or meridian flips.

  • Why do I need this specific PrimaLuceLab adapter for my Borg 55FL f/3.6 and ESATTO 2"?

    This adapter is engineered to provide a direct-threaded, zero-flexure connection between the ESATTO 2" focuser and the Borg 55FL f/3.6 telescope body. This is critical for fast optical systems where any tilt can degrade image sharpness. It also ensures the correct mechanical spacing and alignment within your imaging train.

    Can I use a generic 2" adapter with my ESATTO 2" and Borg 55FL?

    While a generic adapter might physically fit, it will likely use a compression ring or set screws, which are prone to introducing tilt and flexure. For an f/3.6 astrograph, this is unacceptable for serious imaging. This dedicated adapter provides the rigid, threaded connection required to maintain optical alignment and achieve sharp stars across the entire frame.

    Does this PrimaLuceLab adapter allow me to control my Borg 55FL focuser with PLAY software?

    Yes. By securely connecting the ESATTO 2" focuser to your Borg 55FL, this adapter enables full control of the focusing system through PrimaLuceLab's PLAY software. This unlocks capabilities like remote operation, temperature-compensated focusing, and integration with other PrimaLuceLab devices.

    What is the main benefit of adding an ESATTO 2" to a Borg 55FL astrograph?

    The primary benefit is achieving precise, automated, and repeatable focusing. The ESATTO 2" allows for incredibly fine focus adjustments that are essential for maximizing the performance of the Borg 55FL's fast f/3.6 optics. It eliminates focus shift from temperature changes and allows you to maintain perfect focus throughout an imaging session without touching the telescope.

    Will this adapter maintain the correct back focus for my Borg 55FL f/3.6 imaging train?

    This adapter is designed as a direct mechanical interface between the ESATTO 2" and the Borg 55FL. You will still need to use the appropriate spacers and extenders between the focuser and your camera to achieve the specific back focus distance required by your complete optical configuration (including any flatteners or reducers).

    How does this adapter improve my imaging results on the North American Nebula (NGC 7000) with the Borg 55FL?

    When imaging a large, faint object like the North American Nebula (NGC 7000) with the wide field of the Borg 55FL, edge-to-edge sharpness is critical. This adapter ensures your entire imaging train is rigid, preventing tilt that could make stars in one corner of the nebula appear soft or elongated while others are sharp. This mechanical stability is key to getting the most out of your high-end optics.
