Usage tips

1. Start at 24 mm. First, focus at the lowest magnification for the brightest, widest image on fainter objects.
2. Zoom in quietly. Slowly turn to shorter focal lengths to increase magnification. Refocus in between if necessary.
3. Maximum achievable magnification. When the seeing or object no longer allows a sharp image, return to a lower magnification.
4. Filters? Rather not. Due to the limited thread, we do not recommend mounting filters on this eyepiece; this may cause damage.

Sample magnification calculation

Magnification = Focal length of telescope ÷ focal length of eyepiece
Thus, for a 1000 mm telescope, this eyepiece results in 1000 mm ÷ 24 mm = 42× to 1000 mm ÷ 8 mm = 125×.
