Celestron 7mm 1.25" 82º Luminos Eyepiece

This sharp 7mm Celestron Luminos eyepiece has a wide and flat 82° field of view for "picture window" views, even at very high powers .

This exceptional Celestron 7mm Luminos short focal length ultra wide field eyepiece uses seven optical elements for optimized performance across a very wide 82° field of view. The Celestron Luminos is a good choice for flat field fast focal ratio refractors. With these scopes, it combines a reasonably high magnification with a very wide field of view for observing globular clusters and the more compact open clusters and nebulas. With long focal length flat field scopes, such as the Celestron EdgeHD models, it provides high magnification for splitting closely spaced binaries, along with a dark sky background to help compact galaxies and nebular remnants reveal themselves.

For example, it will give you a 0.71° field (nearly one and a half lunar diameters) at 116x with a 4" f/8 refractor like the Takahashi TSA-102S triplet apo. With an 8" f/10 Celestron EdgeHD scope, it will give you a 0.28° field (still over half the diameter of the full moon) at a stout 286x magnification.
