essentially yes... Its a canon tele-extender that has a male bayonet mount on the back to attach to the camera like a lense, and at the front it has female bayonet mount to attach either a lens, or T-ring for astrophotography. The one in question, the TE1.4x multiplies the lenses focal length by 1.4, so a 200mm F/4 becomes a 280mm F/5.6 or a 8" F/8 telescope @ 1624mm becomes 2273mm F/~11.7 or there abouts. Would be very useful in some situations to gain the nesscasary magnification on some targets like M104...
