Meade LX200-ACF Optical Tube Assembly

The ACF design corrects for coma and astigmatism, which are common optical distortions that cause stars at the edge of your frame to look stretched or blurry. This results in a flat, sharp field of view across the entire image, making it ideal for astrophotography.

No, this is an Optical Tube Assembly (OTA) only. You will need to provide your own compatible equatorial or alt-azimuth mount that can support the 35-pound weight of the tube.

During long exposures, the primary mirror can sometimes shift slightly due to gravity as the telescope moves, which ruins your focus. The mirror-locking mechanism physically secures the mirror in place, ensuring your focus remains consistent throughout your entire imaging session.

Yes, this OTA comes equipped with a Losmandy-style dovetail plate, making it compatible with any standard Losmandy-style mounting system.

These specialized coatings are applied to the optical surfaces to maximize light transmission. This results in brighter, higher-contrast images, which is particularly helpful when observing or photographing faint deep-sky objects.

While the single-speed focuser is capable, many serious astrophotographers eventually upgrade to a dual-speed or electronic focuser for finer control. For visual use, the included focuser is generally adequate, but imaging often requires the micro-adjustments that a dual-speed system provides.
