Sensor Tilt: The Problem
Introducing the Wanderer Astro Electronic Tilt Adjuster, or ETA for short! Astrophotographers know how frustrating sensor tilt can be. When heavy cameras and filter wheels sag under their own weight, the sensor may no longer sit perfectly parallel to the focal plane, resulting in distorted stars across parts of the image. Correcting this traditionally requires adjusting push/pull screws one at a time, capturing test images, and repeatedly checking the results—a time-consuming process that can take hours or even multiple nights. The unit features an M54 female telescope-side connection and a native screw connection on the camera side, which can be converted to M54 female threads with an optional adapter (sold separately).

How Does the Wanderer ETA Work?
The Wanderer ETA features M54 threads and permanently inserts into your image train near the focuser. The ETA features three motors that are evenly spaced 120º apart, and each one can independently move each part of the image train outward or inward. When paired with software like NINA that can measure star shapes and Wanderer's own software, the ETA can make micro adjustments as small as 0.3 microns to precisely correct for tilt.
Unique Patented Structural Design
With an ultra-thin thickness, the Wanderer ETA occupies only 5mm of back focus or focuser travel when directly connected to the OAG or camera using screws. It weighs just 470g. Additionally, it features a dual-layer nested structure that eliminates any light leakage.
55mm Back Focus Possible!
The Wanderer ETA can be directly mounted in front of an OAG or camera using screws and, in most cases, still maintain a 55mm back focus. For detailed installation instructions and device compatibility, please refer to the user manual.
Three-Point Electronic Tilt Adjustment
The Wanderer ETA features three independent adjustment motors and three high-precision encoders, offering an adjustment range of 1.2mm with a motor resolution of 0.3 micron per step and a positioning accuracy of up to 2 microns. Compared to traditional manual tilters, this achieves a precision several orders of magnitude higher, fully meeting the demanding tilt and back focus adjustment requirements of fast focal ratio systems and large-format cameras.
Low Temperature Resistant Design
Tested under extreme conditions, the Wanderer ETA remains fully operational even at -20°C (-4℉), making it resilient against harsh winter environments.
Professional Design
The Wanderer ETA is composed of nearly 1,000 curved surfaces and over 50 components. Every detail has undergone professional analysis, precise calculations, and countless optimizations to ensure the highest level of rigidity.
Unparalleled Aesthetic Design
WandererAstro's aesthetic design never disappoints. Every rounded corner and every carefully sculpted curve make the Wanderer ETA not just a precision instrument but also a beautifully crafted piece of art.
Software Support
The WandererEmpire software provides an excellent control and visualization interface for the Wanderer ETA. Note: The camera, OAG, and other equipment shown in this page are for installation demonstration purposes only and are not included with the Wanderer ETA.
