The Meade ETX-90/EC Maksutov-Cassegrain Optical System | |
In the optical design of the ETX-90EC, light enters from the right through a multi-coated meniscus lens, proceeds to an f/2.2 primary mirror, and then to a convex secondary mirror that multiplies effective focal length by a factor of 6.3. The secondary mirror baffle in combination with the antireflection threads inside the primary mirror baffle, produces extremely high contrast astronomical images at the focal plane. The oversize 96mm diameter primary mirror results in fully-illuminated (unvignetted) fields of view significantly wider than can be obtained with Maksutov optics incorporating primary mirrors of the same aperture as their correcting lenses. |
