1/9/2024 0 Comments Celestron rasa 8 inchThis 8″ model is the most recent addition to the RASA lineup. For a much more affordable cost compared to longer focal length telescopes, the 8″ RASA is capable of capturing spectacular images of deep sky objects without the issues typically encountered with these aforementioned systems. Plus, as it weighs only 17 pounds, transporting your 8″ RASA to distant dark sky locations is easy.ĭelivering a flat field free of optical aberrations, this Celestron 8″ RASA imaging telescope provides razor sharp stars over the entire field of view. This combination of a fast focal ratio and patented optical design generates sharp images with superb detail, and, in many instances, allows you to completely skip the autoguider. The 8″ RASA’s awesomely fast f/2.0 optical system works perfectly in conjunction with modern color astronomical CMOS, smaller CCD, and mirrorless cameras. With this new portable Celestron astrograph, the 8″ RASA (Rowe-Ackermann Schmidt Astrograph), you’ll be able to capture breathtaking wide field views of deep sky objects in a matter of seconds. Although similar in size to the CGEM II, the CGX takes it to the next level in terms of performance and features, particularly where imaging applications are concerned. With the addition of a camera, this kit provides all an imager needs to capture stunning wide-field images of deep sky objects. This package pairs the Celestron 8″ Rowe-Ackermann Schmidt Astrograph (RASA) optical tube with the cutting-edge CGX German equatorial mount. Functions supported by the CGX mount’s proven NexStar+ computerized telescope control technology include All-Star Polar Alignment, Permanent Periodic Error Correction (PPEC), and adjustable tracking through meridian.Celestron PWI software is included for direct computer control using a USB 2.0 connection.With optical limit switches, home sensors, through-mount cabling, and hard stops, this system is fully capable of remote imaging.The drive system utilizes low cog DC Servo motors with integrated optical encoders, belt and pulley motor connection, spring-loaded steel worm gears supported by precision sealed bearings, and brass worm wheels for smooth, accurate slewing and tracking performance with little backlash.payload capacity to provide a solid, robust platform that can easily accept a Celestron 8″ RASA OTA with a fully loaded imaging system. The CGX, Celestron’s most original advanced computerized equatorial mount so far produced, offers a 55 lb.Covers a wider spectral range, 390 nm to 800 nm, allowing a greater amount of sharply focused light to pass through.Using an internal filter mount, a Light Pollution Imaging Filter can be flawlessly accepted into the optical path.A new Ultra-Stable Focus System with six precision sealed ball bearings to basically eradicate image shift is included with the 8″ RASA.Optical blemishes like field curvature, coma, astigmatism, and chromatic aberration are completely missing from the flat field across the entire APS-C sensor.Celestron 8″ RASA Astrograph on CGX Equatorial Mount
