Unveil the Cosmos with the Askar 130PHQ Astrograph A Superior Long-Focal-Ratio Imaging Powerhouse Optimized Optical System: The Askar 130PHQ, a continuation of the esteemed PHQ series, offers a long focal ratio of f/7.7 and a focal length of 1000mm. It is engineered with a self-flattening quadruplet lens that includes two ED glasses, effectively controlling chromatic and other aberrations to deliver crystal-clear celestial images. Enhanced Aperture: With an aperture that is 23mm larger than its predecessor, the 107PHQ, the 130PHQ boasts improved light-gathering capabilities, ensuring brighter and more detailed astrophotographic outputs. Perfect Focus with Ease: Designed to simplify the imaging setup, the 130PHQ eliminates the need for additional field flatteners. Astrophotographers can effortlessly achieve perfect focus with any compatible imaging device without the hassle of backfocus calculations. Advanced Imaging Support: The astrograph supports a medium frame 60mm image circle and maintains a central RMS radius of less than 2 microns, minimizing distortion at the edges and ensuring a fine spot diagram across the field. Versatile Reducer Compatibility: The optional 3" 0.7x flat field reducer allows the 130PHQ to reach an impressive focal ratio of f/5.4 and a focal length of 700mm, significantly reducing exposure times for faster and more efficient imaging sessions. Robust Mechanical Construction: The telescope features a high-quality CNC machined and painted tube, complemented by aesthetically pleasing decorative parts. The sturdy 3.4" rigid focuser is equipped with M68, M54, and M48 adapters, enhancing connectivity and flexibility. Multifunctional Handling and Mounting: Includes a multifunctional handle with a central slot for an M6 screw, facilitating easy accessory attachment. The standard Losmandy dovetail plate, coupled with robust double tube rings, ensures stable mounting suitable for both observation and extensive astrophotography. Tailored for Enthusiasts and Professionals: Whether starting in astrophotography or seeking a high-grade instrument, the 130PHQ stands out as a functional and attractive choice, designed to handle diverse observational challenges with ease. Explore the universe with precision and ease with the Askar 130PHQ, where advanced optical technology meets user-friendly design, making it a top choice for both amateur and experienced astronomers.
