Product Description

The new 36mm EFW (Electronic Filter Wheel) independently developed by ZWO for astronomical mono cameras. With the larger body and the newly-added screw holes on the covers, it will give a much easier and more fixable way to connect to ASI cameras.

There are 7 slots inside the EFW and we recommend you use the ZWO 36mm LRGB and SHO filter set with it.

01

The body is CNC milled from an aircraft graded aluminum block. It is made with high quality and thin with the thickness of only 20mm. The heart of the EFW uses the quality stepmotors produced by NPM, Japan, which can be very trustworthy. When photographing, you can rotate the EFW in both counter clockwise or clockwise direction for filter selection. The whole operation process is rather convenient and efficient.

06

Comparing to the original 36mm EFW, you may find the new EFW has a bigger size. The screw holes on the front and back covers shall not only allow us directly connecting the 36mm EFW to the camera and bringing the filters closer to the camera sensor, also making the it possible to match it with M68 OAG.

There are no need for multiple cables to power this filter wheel up, just one USB cable does the trick. The power consumption of this EFW is approximately 120mAh @5V, which can be operated from the Cooled CMOS’s USB hub.

01

All ZWO 36mm filters can be perfectly supported by this EFW. But if you use filters from third party, then please make sure the thickness of the filter should be between 1.5mm and 3.0mm (the thickness of the filter frame is 1.8mm).

    Will this come with screws for new bolt-on connection? I will have the ASI2600MM but I don’t intend to use OAG. So I would bolt on the M42 tilt adapter from the camera to the telescope side of the EFW. New bolts would be needed for this. Then to get 55mm to my telescope flattener, I would add the 2mm T2-T2 adapter that comes with the EFW and the 16.5mm T2-M48 adapter that comes with the camera. This would actually be 56mm, but I have an adjustable flattener.

    If these bolts are not included, can you tell me the thread and length needed?

    Thanks
