  • Adapter M86i to M68i – for TEC 110FL

    This Baader Planetarium adapter creates a solid, threaded connection between the M86 internal thread of a Telescope Engineering Company (TEC) 110FL focuser and the Baader M68i accessory system. By replacing standard slip-fit or compression-ring holders, this adapter eliminates a primary source of mechanical flexure, ensuring your imaging train remains perfectly orthogonal to the optical axis. It is the essential first component for building a professional, rigid imaging setup with the TEC 110FL telescope.

    Eliminate Focuser Flexure on the TEC 110FL

    For professional-level astrophotography, any amount of mechanical flexure can render results unusable. When heavy accessories like large format cameras, filter wheels, or telecentric systems are attached via simple plug-in connections, the leverage can cause tilting that trails stars and degrades resolution. This adapter solves that problem by providing a direct, large-diameter M86i screw coupling to the TEC 110FL's focuser drawtube.

    Integrating the TEC 110FL into the Baader M68 System

    The Baader M68 system is designed for creating robust, versatile imaging trains without weak links. This adapter is the critical bridge that allows the TEC 110FL to securely interface with the entire M68 ecosystem, including accessories like the Baader M68 Tele-Compendium or Fluorit Flatfield Converter (FFC). By converting the telescope's native thread to the widely supported M68i standard, you gain access to a system built to carry the heaviest loads without compromise.

  • What is the primary purpose of the Baader M86i to M68i adapter for the TEC 110FL?

    Its primary purpose is to provide a rigid, secure, all-threaded connection from the TEC 110FL telescope's focuser to the Baader M68i system. This eliminates the potential for tilt and flexure common with standard 2" compression-ring visual backs, which is critical for astrophotography with heavy equipment.

    Why use this threaded Baader adapter instead of a standard 2" visual back on my TEC 110FL?

    A standard 2" visual back relies on thumbscrews and a compression ring to hold equipment. Heavy imaging trains can cause this connection to sag or tilt, ruining long exposures. The Baader M86i to M68i adapter screws directly and securely onto the focuser, creating a solid metal-on-metal connection that cannot flex or tilt, ensuring perfect alignment.

    Does this Baader M86i to M68i adapter work with any other telescopes?

    No, this adapter is specifically designed to match the M86 internal thread on the focuser of the Telescope Engineering Company (TEC) 110FL refractor. It is not a universal adapter and will not fit other telescopes.

    What kind of imaging accessories can I attach to the M68i side of this TEC 110FL adapter?

    The M68i thread opens up the entire Baader M68 accessory ecosystem. This includes:

    • Baader M68 Tele-Compendium: For a rigid, variable-length extension tube and light shield.
    • Baader M68 Extension Tubes: For achieving precise back focus spacing.
    • Adapters to other standards: Such as M68 to M48 or T-2 for connecting various cameras and correctors.
    • Baader FFC: The Fluorit Flatfield Converter for high-magnification planetary imaging.

    For high-resolution imaging of Jupiter with my TEC 110FL and a telecentric system, is this adapter necessary?

    Yes, it is highly recommended. Telecentric systems can be long and heavy, creating significant leverage on the focuser. Using the Baader M86i to M68i adapter ensures the entire imaging train remains perfectly rigid and collimated, which is absolutely critical for achieving the highest possible resolution on planetary targets like Jupiter or Saturn.

    If I build a heavy imaging train for deep-sky imaging on my TEC 110FL, how does this M86i to M68i adapter prevent ruined subs?

    A heavy deep-sky train (large camera, filter wheel, off-axis guider) will inevitably cause a slip-fit adapter to sag as the telescope tracks across the sky. This sag, or differential flexure, causes trailed stars and loss of focus. By creating a solid threaded connection with the Baader M86i to M68i adapter, the entire train moves as a single rigid unit with the telescope, preserving alignment and focus through the entire exposure.
