  • IMP85 Adapter S120a to M68i

    This IMP85 Adapter S120a to M68i is the critical link for integrating M68-threaded accessories into the advanced 3-port IMP85 instrument selector system. It provides a secure, precisely machined connection between the selector's S120a interface and the widely used M68i internal thread standard. This adapter is a required component for building a custom, multi-instrument setup around the IMP85 core unit.

    The IMP85 System: Switch Between 3 Instruments Instantly

    Developed for the demands of remote observatories, the IMP85 Instrument Selector (sold separately) allows you to permanently mount three separate optical trains on a single telescope. The primary, non-mirrored Port 1 offers a direct, loss-free light path for your main imaging camera. Two additional ports can be engaged via electronically controlled, high-precision mirrors, allowing you to switch instantly to a planetary camera, spectrograph, or eyepiece without reconfiguring your setup.

    This eliminates the need for manual equipment changes, saving valuable time after public viewing sessions or enabling fully remote operation. With the IMP85, an observatory can transition from deep-sky imaging to planetary observation or spectroscopy at the touch of a button, making it a powerful hub for both amateur and professional astronomy.

    The S120a to M68i Adapter: Your Link to M68 Accessories

    The IMP85 unit is delivered without adapters to ensure maximum modularity. This specific S120a to M68i adapter is designed to connect one of the IMP85's ports to any accessory that uses the M68 internal thread. This is essential for attaching many popular field flatteners, coma correctors, off-axis guiders, and camera systems that rely on the robust M68 standard for a wide, stable image train.

    By choosing the correct adapters like this one, you can ensure all three of your instruments are connected securely and with a defined backfocus, allowing for near-parfocal performance across your entire system. This component is not a generic adapter; it is a purpose-built part of the IMP85 ecosystem, designed for a rigid and reliable connection.

  • What is the purpose of the IMP85 S120a to M68i Adapter?

    This adapter's sole function is to connect an accessory with an M68 internal thread (M68i) to the S120a port of the IMP85 Instrument Selector. It is a necessary component for integrating M68-compatible hardware into your IMP85 setup.

    What kind of M68i equipment can I connect to my IMP85 for imaging the Orion Nebula (M42)?

    For deep-sky targets like the Orion Nebula (M42), you would use this adapter to connect M68-threaded components such as a field flattener, a coma corrector for a Newtonian, or a large-format astronomy camera directly to one of the IMP85's ports. This ensures a wide, stable, and correctly spaced imaging train.

    Is this adapter included with the main IMP85 Instrument Selector?

    No. The IMP85 Instrument Selector is sold as a core unit without any adapters to allow for maximum flexibility. You must purchase the specific adapters, like this S120a to M68i model, that match the connection types of your telescope and camera-side equipment.

    How does the IMP85 system benefit a remote observatory with an SCT?

    For a remote observatory using a Schmidt-Cassegrain Telescope (SCT), the IMP85 system is transformative. You can permanently mount a deep-sky camera on the main port, a high-speed planetary camera on a secondary port, and a spectrograph on the third. You can then switch between these instruments remotely without any physical intervention, maximizing the telescope's uptime and research capability.

    How do I determine the correct adapter, like this S120a to M68i model, for my IMP85 setup?

    You need to identify the thread or flange type on both your telescope side and your instrument side (camera, spectrograph, etc.). The IMP85 system uses a variety of adapters to connect these components. If your instrument has an M68 internal thread, and you are connecting it to the IMP85's S120a port, this is the correct adapter.

    Can this adapter be used without the IMP85 Instrument Selector?

    No, this adapter is specifically designed to bridge the S120a and M68i standards within the IMP85 ecosystem. It is not intended for general use as a standalone M68 adapter in other optical trains.
