Description
This is the bracket and belt tensioner/focuser adapter to house ZWO EAF onto William Optics Redcat 51 (original version with helical focuser, not the WIFD version). The bracket come with one housing spot for the ZWO EAF, and one additional 32-34mm vixen style dovetail mount for guide scope or other accessories. It clears the original saddle plate of Redcat 51.
The belt tensioner/adapter works with 6mm GT2 belt and the D78mm diameter helical focuser of the Redcat 51. It's a modify from GT2-Belt Tensioner by Create_Tec @Create_Tec_731911 on Printables.
To function properly, you need the following hardwares:
For the bracket:
- One M4 x 40mm normal screw or thumb screw
- One M4 x 8mm thumb screw (for the dovetail)
- Two M4 x 8mm screws (for securing the EAF, comes with the EAF)
- Two M4 nuts
For the belt tensioner/focuser adapter

[Optional] If you want to mount a ASIAIR on the dovetail mount, you may want to print a taller foot for the ASIAIR to clear the belt tensioner/focuser adapter. I made one here: https://makerworld.com/en/models/733411#profileId-665117
