Electronic Focus Accessory (EFA) Kit
$920.00 – $1,150.00
- The EFA kit automates focusing on the optional Hedrick Focuser, or IRF90 rotating focuser.
- Monitors temperature (primary-mirror and OTA back-plate).
- Controls the fans built into CDK telescopes.
- Ensure you have the proper EFA kit selected for your telescope below.
- 125901-Kit is for all 12.5″ OTAs (CDK/ IRDK).
- 240901-Kit is for all 14-24″ OTAs (CDK/ IRDK/ RC) and CDK700s.
*If the EFA is not purchased, the ability to automate temperature regulation for the primary mirror will be lost. This is especially significant when using a third-party focuser, as the EFA is required for full automation.
