Dark current

low iron-tempered glass with enhanced stiffness and impact resistance

~95% transmission at 496nm (OIII)

This dramatically improves contrast on emission nebulae while greatly reducing the effects of light pollution and moonlight

We recommend using a 2 inch high anti zenith mirror for maximum light and optical quality, coupled with high quality wide angle eyepieces. When observing conditions permit, the best magnification for observing the moon and planets is within 200 times, which is also impressive.
