Can I use this helical focuser with the ZWO 60280 Finder and Guide Scope? I bought this focuser with the intent of using it with this guide scope, but it does not seem to easily attach. Any suggestions? I am trying to avoid rotating the camera while focusing.
Support@ZWO – January 26, 2021:
It is designed to fit with OAG. There is no need to add this focuser to guide scope.
Mark – January 14, 2021:
Is this a non-rotating focusser?
Also, can I put this between the ASI120MM-S and 30F4 mini scope? The focusser on the guide scope rotates the image when it is rotated which makes it tricky to get right.
Support@ZWO – January 14, 2021:
This can only be used with our mini camera.

Would this helical focuser work with the 462MC fitted with the 1.25″ nose piece adaptor & OAG to provide easier focusing when using the OAG? Or will the focuser make the gap from the sensor to prisum too big to focus properly?
sara.liu – November 2, 2020:
Sorry that the HF1.25 only can work with MIni cameras. If you have one ASI462MC camera, OAG can be worked with ASI462MC directly.

How much does this weigh? It is listed as 80-100gm. How can it weight two different weights? Is it 80gm or 100gm? Need this information to determine balance and mount loading. Thanks.
ZWO.Moson – October 9, 2020:
The weight of this Helical Focuser is about 100g.

Can it be used in the main focus for planetary photograph with asi120mc/asi290mc?
Just use the main telescope (127mm MAK) to focus, and then then fine focussing with the helicoidal focuser?
The bottom female thread and top male thread are both M42*0.75. It requires your telescope has M42*0.75 male thread.

would it be possible to get the CAD file for this part? STEP file? greatly appreciated.

Sorry we do not provide this.
does this fit into an EFWmini?
It is designed to fit with OAG.

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.
sebastain – November 23, 2019:
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.
