مُركّز "No-Shift" لتلسكوبات Celestron Schmidt-Cassegrain

Finally got this installed on my C11, and the compression ring holds my heavy camera setup rock-solid with zero image shift. The 1.5-inch draw tube travel gives plenty of room for reaching focus with a focal reducer attached.

The dual-speed knob lets me fine-tune focus precisely, and the compression ring grips my eyepiece securely without any slipping.

Finally, no more image shift when I lock focus. The dual-speed knob lets me fine-tune on Jupiter without jiggling the whole tube, and the brake holds rock-solid. Only wish the adapter was included, but once paired, it transforms the scope.
