Good fit. In the Celestron StarSense Explorer LT 80AZ the Tele Vue 11mm Nagler Type 6 gives 82x with a 1 degree true field and a 1 mm exit pupil, inside the telescope's useful range.

Magnification is the telescope focal length divided by the eyepiece focal length: 900 mm divided by 11 mm is 82x. The true field of view is the eyepiece's 82 degree apparent field divided by that magnification, 1 degrees.

The exit pupil, the width of the light beam leaving the eyepiece, is the aperture divided by the magnification, 80 mm over 82x, which is 1 mm. That makes this a high-power lunar, planetary and double-star setting.
