This component allows you to integrate a versatile instrument-switching system into your PlaneWave telescope, enabling remote, automated changes between your primary camera and two secondary instruments. For remote observatories or complex imaging setups, this adapter is the key to unlocking the full potential of the IMP85 system without compromising the rigidity of the optical train.\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: A Three-Port Instrument Selector for Remote Observatories\u003c\/h3\u003e\n\u003cp\u003eThis adapter is designed for the IMP85, an instrument selector built to eliminate manual reconfiguration. The system allows an observatory to keep a deep-sky astro camera, a high-speed planetary camera, and a spectrograph permanently mounted and ready for use. For public observatories, a camera can remain on the main telescope while an eyepiece is brought into the light path for guests with the push of a button, saving valuable time after events.\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\u003eUnobstructed Main Port and Dual Mirrored Side Ports\u003c\/h3\u003e\n\u003cp\u003eThe IMP85 system's design is distinct from other instrument selectors. The primary optical path, Port 1, is a direct, straight-through connection with no intervening mirror, ensuring no light is lost on the way to your main imaging camera. Two secondary ports are accessed via electronically controlled, 40x40mm fused silica mirrors that can be inserted into the light path with extremely high repeatability, directing the beam to a spectrograph, guide camera, or eyepiece with precision.\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\u003eSeamless Connection to PlaneWave SecureFit Systems\u003c\/h3\u003e\n\u003cp\u003eThe S120a adapter creates the physical, threaded link between the IMP85 body and the PlaneWave SecureFit focuser system. Its purpose is to translate the IMP85's native S120 thread to the PlaneWave standard, maintaining a rigid, flexure-free connection essential for serious imaging. By using this adapter, you ensure that the precision and stability of your PlaneWave telescope are fully preserved when adding the instrument-switching capabilities of the IMP85.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the main purpose of the IMP85 Adapter for PlaneWave SecureFit?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThis adapter's sole function is to physically connect the IMP85 instrument selector to a PlaneWave telescope's SecureFit focuser.

Unlike systems that use a central rotating mirror, the IMP85's main port has no mirror, ensuring the maximum amount of light reaches your primary imaging camera without any degradation.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eCan I use an eyepiece with the IMP85 system on my PlaneWave telescope?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eYes. One of the key applications is mounting an eyepiece on one of the two secondary, mirrored ports.
