The WandererAstro WandererRotator Mini is a lightweight and ultra low-profile M54 motorized rotator. It is capable of high speed and precision, at up to 4.5 degrees/second with better than 0.1 degree accuracy*. At only 10mm thick, the Mini rotator is ideal for setups where backfocus is limited.
The Mini rotator is capable of holding a payload of up to 5Kg with a centre of gravity 10cm away from the rotator. WandererAstro's patented magnetic structure design guarantees zero flexure at any altitude. For users of alt-azimuth mounts and Dobsonians, field de-rotation is supported.
The Mini rotator is entirely powered and controlled from a single USB 2.0 type B port that can supply at least 5V at 1A. The Mini rotator is ASCOM compatible and can be controlled by modern astrophotography software such as N.I.N.A.
*Accuracy can reach a maximum of 0.1 degrees after two attempts and after backlash compensation has been correctly set.
Note: If you want to connect the ZWO EFW 2" filter wheels to the Wanderer Rotator Mini, you will require an extra 1mm M54 spacer for clearance (even when using the ZWO M54 male to male adapter). Without this, there will not be enough clearance between the rotator body and filter wheel.
||USB 2.0 type B (5V 1A minimum)
|Optical thickness||10 mm (between M54 threads)

||Torque generated by imaging train to rotator must be less than 5 Nm
||M54 x 0.75 female on both ends|
Folks, personally spend a bit extra and get a tested and proven unit. The Rotator itself is not too bad from a construction perspective. What is evident though are bugs in the driver that have been confirmed by the manufacturer where by the feedback from the servos may go haywire and present an output that does not represent the actual positioning of the rotator. If this happens when you are imaging you have lost the nights effort.
The big issue with the version that I purchased ( and current version available ) is that there is a design flaw whereby there is 5 volts present on the USB interface and also 5 volts present on the 12 volt input plug. Because of this one needs to be very conscious of having active voltage on the plug to the rotator. The manufacturer has stated they are putting a diode on the next version to counter this back voltage on the USB side but have not confirmed the positive voltage on the 12 volt input terminal if plugged into an USB powered hub or control unit. I was told by the manufacturer if I was using a controller such as the Wanderer or Pegasus units to turn off the USB interface via the software before unpluging.
Personally if you can afford it, buy something of better quality. The unit does rotate and has next to no backlash so I cannot complain re the mechanical aspects of it but be aware that if the driver has issues, getting a zero degree position will mean starting from scratch.. Overall reliability is probably what you would expect for the cost.
