Is anyone using Antlia 1.25 Pro NB filters in a ZWO EFW?

Hi everyone,

I'm interested in the Antlia 1.25 Pro NB filters. Can anyone confirm that they fit in a ZWO EFW and there is enough clearance for the filter wheel to rotate?

I have the 8 X 1.25 ZWO EFW.

Thanks,

Andy

I'm not sure about the Antlia brand but with my astrodon filters they will fit, but I have to turn the faceplate round. Still works perfectly fine.

Interesting as i have good clearance with my 1.25inch Astrodons, What I find is that its not the filter wheel that causes issues its some t2 extenders whos thread is too long and protrudes into the wheel when fully tight. As I generally need 1-2mm of spacers to adjust back focus for the 3mm thick astrodon filters I just place them on that thread and everything is fine.
