The Sky-Watcher S20301 M48 Camera Adaptor enables you to attach a Nikon DSLR camera to a Sky-Watcher 0.85x Focal Reducer/Corrector. This is a larger ring than standard T2 size, and it is designed to accommodate larger format imaging systems to ensure maximum light throughput and complete coverage of the imaging sensor. This M48 ring can be used on the Esprit and ProED series with the dedicated field correctors and should not be used on their collapsible Dobsonians.
