Professional 150 mm motorized flat panel for telescopes, ASIAIR/StellaVita, ASCOM and INDI compatible. Built-in dew heater, precise ±0.25° encoder, and reliable remote control, operating down to –25 °C for demanding astrophotography.
The WandererCover V4-EC 150 mm is a premium motorized flat panel designed for serious astrophotographers. Compatible with ASIAIR, StellaVita, ASCOM and INDI, it mounts easily on most telescopes. Its upgraded motor provides over 50 % more load capacity for enhanced durability and quieter operation.
The built-in encoder delivers accurate position feedback with ±0.25° repeatability for remote monitoring. Integrated heating keeps the panel dry all night or quickly evaporates dew at dawn. The doubled PWM dimming frequency ensures uniform illumination without banding, even at 0.1 s exposures. Tested for over 3 000 open/close cycles, it performs reliably down to –25 °C.
Package includes a 1 m USB 2.0 cable, a 1 m DC5521 power cable, and four nylon cable ties for effective cable management.

Exclusive cable management solution prevents damage to power cables during operation; Soft cushioning pads protect your telescope from scratches; Includes cable ties for universal installation

Built-in micro-encoder provides real-time, accurate feedback on cover position, allowing users to remotely check the angle status without opening the monitoring camera. Repeat positioning accuracy of up to ±0.25 degrees ensures precise open/close operations every time. Customizable opening/closing at any angle.

Features a brand-new motor with over 50% increased load capacity, ensuring durability and preventing gear box failure. Designed to withstand low temperatures, it operates reliably even in winter conditions as low as -20°C! After testing, the life of WandererCover V4-EC exceeds 3,000 opening and closing cycles.


Thanks to the encoder, V4-EC provides automatic detection of the open and closed position*. If your device is not around and manual setting is not possible, WandererCover can automatically detect obstacles and set the open and closed position.
*It is always recommended to set the open and closed angles manually! Use automatic detection as the last option only when the flat panel angle cannot be observed. It is normal for the motorbox to heat up during automatic detection. The angle detected is affected by many factors and success is not guaranteed. Do not try multiple times if unsuccessful.

The new ASCOM driver makes use easier. It also supports automatic or manual port selection and connection of up to 6 devices simultaneously.

The new dimming controller boosts PWM dimming frequency by 100%, effectively reducing the occurrence of banding and ensuring no banding during exposures of 0.1 seconds or longer. 255-level dimming meets the flat-field shooting needs, from color cameras to narrowband imaging. At maximum brightness, capturing 3nm narrowband only takes around 1 second!

Low temperature resistant design, able to work normally in environment as low as -25℃ (-13℉).

With the latest firmware, it supports control via ZWO ASIAIR Plus, ToupTek StellaVita, and any device capable of controlling the DC switch. Please refer to user manual to check it out!
