Need to change the eyepiece?  The Half Hitch's caliper disc altitude brake will accurately and securely hold your telescope's position during the changeover.  Since a disc brake does not apply torque to the shaft or bearings, the telescope will not be turned inadvertently by braking.  Your scope stays on target!

The Half Hitch's adjustable zenith stop prevents your telescope from accidentally bumping the tripod or mount when turned to the zenith.  The horizon stop prevents accidental bumps in the other direction.

Do I Have To Rebalance After Every Eyepiece Change?

Of course not!  Unless you have an eyepiece that is dramatically different in weight from the others, just set the balance for a middleweight eyepiece.  The Half Hitch's drive system has a generous positive grip that will easily overcome moderate balance shifts.  But if you switch between eyepieces that differ significantly in weight, you can easily and quickly neutralize the balance using the Half Hitch's Balance Trimmer.  You will quickly learn where to preset the trim weight for perfect balance of each eyepiece.

The caliper disc brake provides a convenient means of momentarily dealing with the extreme imbalance that occurs when changing out heavy eyepieces.  The caliper disc brake should not be confused with a clutch or a drive lock.  The Half Hitch's drive system is always engaged and has no clutches to adjust.
