The Meade Instruments 12-inch LX200-ACF 10-inch f/10 LX90-ACF Advanced Coma-Free Telescope is an impressive astronomical instrument designed for serious observers and astrophotographers. This Ritchey-Chr tien type telescope boasts an advanced coma-free optics system, which effectively eliminates coma and other optical aberrations, ensuring sharp and crisp images across the entire field of view.
The 12-inch primary mirror, made of high-quality borosilicate glass, delivers an impressive light-gathering ability, making it an excellent choice for observing faint deep-sky objects. The 10-inch f/10 secondary mirror provides an ample focal length of 120 inches, offering a wide field of view and a high-resolution imaging capability.
The Advanced Coma-Free (ACF) system utilizes a unique mirror design, which includes an integral corrector plate at the primary mirror's focus, correcting for optical aberrations that can degrade image quality. The system is further enhanced by Meade's AutoStar II computerized control system, which offers a database of over 100,000 celestial objects, and can guide the telescope to the desired target with remarkable precision.
The LX200-ACF telescope comes with a robust and sturdy mount, capable of supporting the weight of the telescope and providing accurate tracking. The mount features dual fork arms, which reduce flexure and improve stability, making it an ideal choice for long exposure astrophotography.
Additionally, the telescope comes with a number of convenient features, such as a built-in hand controller, a dual-speed 30,000-step-per-revolution (2 per step) Altazimuth drive system, and a removable dew heater, which helps prevent dew build-up on the telescope's optics, allowing for extended observing sessions.
The Meade 12-inch LX200-ACF 10-inch f/10 LX90-ACF Advanced Coma-Free Telescope is a versatile and powerful astronomical instrument, suitable for a wide range of observing and imaging applications. Its advanced optics system, robust mount, and user-friendly features make it an excellent investment for astronomers and astrophotographers looking to explore the wonders of the night sky.

Still works perfect. This is used and as is, workers perfectly. See picture comes with everything you in picture, lenses, laser climate, power supply and a cell phone adapter to take pics tripod. Electronics include the advanced Meade 497 Audio Star computer system with over 30,000 object library, multiple guided tours, High Precision Pointing capability, and Smart Drive Permanent Periodic Error Correction.
The cord for the audio star cable is missing its clip in. To buy this now new is 4k. USA shipping only. Precise and quick star alignment is done near effortlessly with an incorporated 16 channel genuine Sony GPS receiver.
There is something small on lens has been there since I purchased, don't know if its a particle or defect. This system also reduces the astigmatism and eliminates diffraction spikes found in classical Richer-Chretien designs. No competing Schmidt-Grosgrain Telescope can make those claims. The mount also has mechanical locks in both axis allowing adjustment even without power.
The 10 LX90-ACF has a diameter f/10 ACF optical system focal length 2500mm and Ultra-High Transmission Coatings UHTC for maximum image brightness contrast. See pictures before purchase.
