Product Details
This bracket is designed to work directly with current model Celestron 8" and 9.25" SCT and EdgeHD optical tubes*. You can directly connect it to the scopes without using a Feather Touch Microfocuser (FTM) - it will not work with scopes that have the FTM installed.
It is CNC milled from an aircraft graded aluminum block.
Supported Models:
- 8" Rowe-Ackermann Schmidt Astrograph (RASA 8)
- 8" EdgeHD optical tube assembly
- 8" C8 optical tube assembly
- 9.25" EdgeHD optical tube assembly (without reducer; if using the reducer, you will have to sand/shave off a bit of one side of this adapter to make it fit)
- 9.25" C9.25 optical tube assembly
*Rear cell castings must have triangular molding. Not compatible with older OTAs with flat back cells. May have swing through problems with Celestron NexStar Evolution or CPC OTAs. If you are not sure about compatibility for telescopes other than those listed above, please check the detailed adapter specifications provided in the photos above to check this yourself.
Important Notice About EAF Shaft Compatibility:
The ZWO EAF-STD and EAF-5V (both of which have been discontinued) had a 5mm motor shaft that the coupler included with this item is directly compatible with. However, the new EAFN and EAF-PRO models now feature a smaller 4mm diameter shaft. According to ZWO, while testing shows that using a 5mm coupling with the new 4mm shaft still works "within acceptable tolerances" in most cases, it may not be ideal for some users demanding precision.
ZWO will soon begin including an extra 4mm coupling with this bracket to ensure full compatibility with the updated EAF Pro and EAF-N, but users wanting the new 4mm coupler should NOT buy this adapter at this time until the new version is released.
