Good fit. In the Celestron C6 optical tube the Tele Vue 24mm Panoptic gives 62x with a 1.09 degree true field and a 2.4 mm exit pupil, inside the telescope's useful range.

Magnification is the telescope focal length divided by the eyepiece focal length: 1500 mm divided by 24 mm is 62x. The true field of view is the eyepiece's 68 degree apparent field divided by that magnification, 1.09 degrees.

The exit pupil, the width of the light beam leaving the eyepiece, is the aperture divided by the magnification, 150 mm over 62x, which is 2.4 mm. That makes this a medium-power general setting.
