This flexure is is no problem if you observe only visual, but for photography or spectroscopy any deficiencies will make your results unusable. So, you do not only need a sturdy mount with a robust connection to the telescope, but also a very good focusser – with a sturdy connection to equipment like cameras or others sensors, especially if they are used with long accessories like telecentric systems. Usually, these accessories are only attached with a simple plug-in connection. Even with good, self-centering eyepiece-holders with brass clamping ring long accessories can tilt because of the long lever. This tilt will impair professional operation.

Once you try one, you'll never go back to simple set screw or even captive brass clamp rings again!  With a gentle twist of the outer ring, two special non-marring rollers cam into contact with the eyepiece and firmly lock it into the holder.  The 3-point clamp action guarantees none of the eyepiece wobble common in all single screw clamps or Takahashi lockring style holders.  The lack of a protruding lock screw also eliminates one of the annoying hassles of standard holders - no more contortions trying to trying to work your nose around an  inconveniently positioned screw.\u003c\/span\u003e\u003c\/p\u003e\u003cp class=\"MsoBodyText\" align=\"justify\" style=\"background-color: rgb(255, 255, 255);\"\u003e\u003cspan style=\"font-size: 10pt;\"\u003eThe holder is precisely machined to fit your eyepieces with a minimum of slop, resulting in a close accurate fit that keeps your eyepiece properly centered on the optical axis.

On the output, Baader has added two additional unique and useful features.  The top of the holder is actually an adjustable micro-focusing collar, with 6.5mm of travel.  It allows you to precisely vary and set the overall clamp's height to allow fine adjustment of focus or height for matching other accessories.  Furthermore, this ring is removable, which exposes an external T-2 thread.
