Must be disconnected to adjust

I thought the tube extended while installed. But it's just another tube that must be adjusted before attaching camera or filter wheel. Then alignment and calibration gets out of wack. My off axis camera needs variable focusing depending on primary mirror adjustment. Can't do it with this tube. Disappointing
