Meade LX200-ACF Optical Tube Assembly

Advanced Coma-Free (ACF) optics are designed to eliminate coma, a common aberration where stars at the edge of the frame look like little comets. This results in a flat field of view with pinpoint stars across the entire image, which is essential for high-quality deep-sky imaging.

No, this is strictly an optical tube assembly (OTA). You will need to provide your own compatible equatorial or alt-azimuth mount capable of supporting the 57-pound weight of the tube.

During long exposures, the primary mirror can shift slightly due to gravity as the telescope tracks across the sky, which ruins focus. The mirror lock mechanism physically secures the mirror in place, ensuring your focus remains rock-solid throughout your entire imaging session.

The telescope comes with a single-speed focuser, which is functional for general observation. However, serious astrophotographers often choose to upgrade to a dual-speed or electronic focuser to achieve the micro-adjustments necessary for perfect focus on small sensors.

Borosilicate glass is highly resistant to thermal expansion and contraction. This means the mirror maintains its precise shape even as the ambient temperature drops throughout the night, preventing focus drift and image distortion.

This OTA is equipped with a Losmandy-style dovetail plate. This is a heavy-duty mounting standard that provides a secure, stable connection to your mount, which is critical given the 14-inch aperture and overall weight of the instrument.
