Barlow / Powermate to Mirrorless/DLSR question

Sorry if this is a dumb question.  If I place a 2x powermate between my T-ting and scope is it correct to say my image, on camera sensor, will be 2x as big?  I don't expect exactly 2x, but since I'm imaging direct to sensor and not afocally I want to not botch this due to not understanding something.

cheers all and thanks

A Barlow lens is just a teleconverter, but usually too narrow so you get vignetting, because it is designed to put between eyepiece and eyepiece socket of a telescope. You can rather use a teleconverter for a your DSLR camera and mount that between the camera body and the T-ring adapter.
