Well Made Filter Wheel
Monday, 20 September 2021  | 

Judging by the photographs, I was concerned that this filter wheel might be a little filmy, but in fact it is very sturdy and well made. All parts are aluminium, thick enough to provide a good amount of thread for both the T-2 connectors and the filters themselves. To fit the filters you need to unscrew the front plate of the filter wheel using the supplied screwdriver. The Baader and Astronomik filters that I have fitted perfectly. The wheel rotates smoothly with just the right amount of ‘click’ at each of the five positions. The filter wheel comes with a 1.25” T-2 nosepiece and a 1.25” T2 eyepiece holder with brass compression ring. ZWO also make a T-2 male to T-2 male adapter ring which is useful for fitting the wheel via its T-2 connections rather than the 1.25” barrel.

Feels Expensive, Well Built and Works Great

No need for the ZWO EFW anymore - In my opinion, this works absolutely perfect! It's well built, the filters fit perfectly and it couldn't be any better. Worth every pound!

Very well made filter wheel, it is robust, a bit heavier than I expected for its size and weight, and finely finished. It was a bit gritty when i first received it so I opened it up and re-greased the axle and bearings as well as tuning the locking nut tension slightly. Now it is buttery smooth with a satisfying detent at each position. Very happy with it.

ZWO 5 Position 1.25" Manual Filter Wheel
Friday, 21 February 2020  | 

The ZWO 5 Position Manual Filter Wheel although slightly more expensive than most other products, is well engineered and rotates smoothly. It is smaller and lighter than most other products, weighing approximately just 350 grams, important if your telescope is balance sensitive like my 14in Newtonian. It also has a slightly shorter light path, the thickness of the wheel assembly is just 20mm, but for visual use you need to add on the length of the eyepiece holder which is 24mm making about 44mm in total. However if you have a 2in focuser, the light path can be reduced further if you fit a Tele Vue 2in In Travel adaptor, or replace the T thread to 1.25in nosepiece with a T thread to 2in nosepiece as you then eliminate the light path of the 2in to 1.25in adaptor (about 8mm on average), important if your focuser has limited in travel, which is often the case with Newtonian Reflectors.

If fitting a T thread to 2in nosepiece however, you might also need to add a spacer ring, as otherwise, depending on the length of the thread, it may interfere with rotation of the wheel. Likewise the short (to keep the light path down) 24mm eyepiece tube is shorter than the barrel on some 1.25in eyepieces, and you may need to either not fully insert the eyepiece , or add a parfocal ring, again to prevent possible interference with the rotation of the wheel.

Well constructed Wheel - I’ve moved back to manual for simplicity (and no wiring) after using powered wheel.

This is well made and crucially very soft to operate. i have only had two clear nights to use the scope but all the parts combine well and the subs were in alignment.
