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 - Iíve 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.
