Preguntas Frecuentes
What is the best exit pupil for stargazing?
About 5-7 mm provides the brightest images. For deep-sky objects, 4-5 mm is ideal as it darkens the sky background slightly while keeping objects bright.
Do 7×50 or 10×50 binoculars have a bigger exit pupil?
7×50 = 7.1 mm exit pupil; 10×50 = 5.0 mm. The 7×50 gives a brighter image but less magnification.
How do I measure exit pupil?
Hold binoculars at arm's length aimed at a bright surface. The bright disc floating above each eyepiece is the exit pupil. Measure with a ruler.
