Sony Alpha camera
Designed for attaching a Sony Alpha camera to any of the Sky-Watcher 0.85x Focal Reducer/Correctors.
For larger format imaging
M48 rings are used for larger format imaging. These are different than the standard T-Thread and are not suitable for use on our Collapsible Dobsonian line. M48 rings are to be used on the Esprit and ProED series when using the dedicated field correctors.
