George Pappayliou – January 28, 2020:
Can I use the ZWO Helical Focuser 1.25” with you ASI120MM-S?
Katherine Tsai – February 5, 2020:
It has M42*0.75 male thread on the top which can match up with the female one in ASI120MM-S, but you need to pay attention to the back focus.
Joe B. – December 7, 2019:
I have an ASI174-mini. Should i be using the m28.5-CS adapter and/or the 1.25″ extender when using OAG, EFW 36mm filter wheel, and the 1600mm-pro camera?
Katherine Tsai – December 12, 2019:
Normally I do not use the 1.25″ entender,but it is depend on whether it will get focus. If it is short then you can add this adapter.

I can use the ZWO 1.25″ Helical Focuser with mini zwo scope ?
Katherine Tsai – November 27, 2019:
Yes you can but I think there is no need to add this focuser to mini guide scope.
Ben Stewart – September 24, 2019:
Does this work with regular non-cooled ASI cameras?
ZWO ASI Camera – September 25, 2019:
Yes,you can think of it that way. Because the Helocal Focuser works with OAG, which the one connect to guide camera. In general the guide camera is non-cooled camera.
