This dual-functionality operates within a shared total travel range of 4 mm.\u003c\/p\u003e\n\u003cp\u003eThis shared travel is a critical design trade-off. The more tilt you introduce to correct your optical train, the less travel remains available for focusing. The WandererEmpire software clearly displays the available focus travel, allowing you to manage this balance and ensure you have enough range for your autofocus routines.\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\u003e0.2 Micron Accuracy and USB-C Control\u003c\/h3\u003e\n\u003cp\u003eAt the heart of the FETA M92 is a drive system delivering 236,467 steps per millimeter, resulting in an effective positioning accuracy of 0.2 microns. The WandererEmpire software accepts target positions in steps of 0.001 mm. Control is handled through a USB 2.0 Type-C port with screws, and the unit takes 12 V 1 A power through a DC5521 input (10 to 15 V allowed). The operating temperature range is -30 to 50 degrees Celsius.\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\u003eA 15 mm Optical Path in a 20 mm Body\u003c\/h3\u003e\n\u003cp\u003eThe FETA M92 is designed for modern, back-focus-critical imaging trains. While the total body thickness is 20 mm, the M92 mounting surfaces on each side are recessed by 2.5 mm.

The primary interface is an M92x1 female thread with a maximum allowable engagement of 7 mm; if your accessory has longer threads, you must use spacers.

It gives the three points a fixed reference that the device can find again on its own, which is more reliable for unattended and remote operation.

You can connect up to 6 FETA M92 units from a single PC, choosing the COM port manually (Wanderer devices show a CH340 suffix in Device Manager) or letting the software search for it.

After configuring WandererEmpire with your sensor size and the Hocus Focus save path, the software reads the Aberration Inspector results and calculates the necessary corrections. You run Aberration Inspector, let the FETA M92 adjust, then run it again to check, and repeat; a confidence of 90 percent or more is the target before each move. The Adj Microns values at all four corners can typically be brought within 5 to 10 microns. The focuser step size to enter for the FETA M92 is 0.04, without Reverse. It is important to note that this process corrects for sensor tilt only; it cannot fix poor telescope collimation.\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\u003eFirmware Updates and an Open Serial Protocol\u003c\/h3\u003e\n\u003cp\u003eFirmware updates are handled directly within the WandererEmpire software; disconnect the FETA M92 in WandererEmpire before uploading, or the COM port cannot be opened.
