Hello. For some time I have been unable to use my ZWO EAF with the ZWO OAG-L and ZWO EFW with my 8HD because of the space conflict between the OAG and the ZWO SCT EAF bracket. My solution? The very good Quickswitch EAF SCT Bracket from Starizona https://starizona.co...eaf-sct-bracket.
As you can see in the photo, with the QuickSwitch bracket I was able to move the EAF cube away from the OTA's axis. The QuickSwitch is also an easy solution to have both manual focusing and an EAF installed simultaneously. If you have congestion between the mirror locks, an EAF, and optical gear, this may work for you, too.
