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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe IMP85 System: Switch Between 3 Instruments Instantly\u003c\/h3\u003e\n\u003cp\u003eDeveloped 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.\u003c\/p\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eThe S120a to M68i Adapter: Your Link to M68 Accessories\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eBy 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.
