This is a like new ZWO 7x2" filter wheel - it is completely unmarked and pristine, in perfect condition. This is not the newer 2025 version; this is the previous version, now discontinued. The previous owner brought in a number of "used" items that turned out not to be used at all, and we think that he never used this one either.
However, there are a number of ancillary parts that normally come with this EFW - screws, filter masks, adapters - that are not included. See the third photo, which shows all of these items. This includes the USB cables, and will still work without these other accessories, but these items are necessary if you have special circumstances. Because you will need to procure these items yourself, we have heavily discounted this item from its new price: save TWO HUNDRED DOLLARS off of a brand new one.
Description:
The filter wheel body is CNC milled from an aircraft graded aluminum block.
Excellent craftsmanship, very thin and light with only 20mm thickness.
The core part of our EFW is the stepper motor which has reliable performance and quality that comes from NPM, Japan.
2″ Thread-In Filters or 50.4mm ±0.5mm Unmounted Filters can be used
The 2” Electronic Filter Wheel can be rotated in both counter clockwise and clockwise direction for filter selection.
There is no need of multiple cables to power this wheel up, just one USB cable does the trick. The maximum power supply of this EFW is approximately 120mAh @ 5V, which can be operated from the Cooled CCD’s USB2.0 port.
When connected to ASI6200, the distance from the filter to the sensor is about 18mm
Our 2″ RGBL filters are recommended to work with ASI6200MM Pro camera, it will offer nearly 1:1:1 RGB color balance.
