Fits

Good fit. In the Celestron NexStar 6SE the Tele Vue 41mm Panoptic gives 37x with a 1.86 degree true field and a 4.1 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 41 mm is 37x. The true field of view is the eyepiece's 68 degree apparent field divided by that magnification, 1.86 degrees.

The exit pupil, the width of the light beam leaving the eyepiece, is the aperture divided by the magnification, 150 mm over 37x, which is 4.1 mm. That makes this a low-power, wide-field and deep-sky setting.
