This Apertura 8" Imaging Newtonian is jam packed with features. With its sizable 8" optics, precision-engineered craftsmanship, and thoughtful inclusions, this telescope is an astrophotographer's dream! Read more about this 8" Newtonian telescope below.
8" of Aperture
Housing a large 8” (203 mm) aperture, this Apertura telescope collects a copious amount of light for impressive resolution of detail. An aperture of this size provides excellent illumination across your sensor, making it a choice telescope for those looking to expose faint deep space objects. Also, the speedy f/4 focal ratio is wonderful for capturing photons efficiently, while the 800 mm focal length delivers a moderately wide field of view of the night sky. Large celestial targets fit nicely within your frame, such as the Andromeda Galaxy, the Rosette Nebula, the California Nebula, and plenty more!
Expertly Crafted
In addition to exceptional optical performance, this Apertura 8” Newtonian is built to last. With its rolled steel tube, you can expect high resistance to dents and scratches along with ample support for your imaging gear. The interior of this OTA is painted matte black to put a damper on internal reflections, providing you with the utmost image quality. For easy collimation, the center-spotted primary mirror is secured within an aluminum cell fitted with six "push/pull" collimation knobs. This allows for quick, on the fly mirror alignment without the need for tools! Four ultra-thin spider vanes hold the secondary mirror in place. Though slender, these vanes provide maximum stability for resistance against misalignment and vibrations.
Dual-Speed Crayford Focuser
Helping you dial in the details is a 2” dual-speed Crayford focuser. With two speeds at hand, finding focus is quick and easy! First find rough focus with the large knob, then fine-tune with the smaller, 10:1 micro-focusing knob. A locking knob is included to hold your focus in place. Like the rest of this telescope, this focuser is built with durability in mind, housing a monorail to uphold stability and keep drag to a minimum. A tension knob enables you to adjust any drag on the draw tube to match the weight of your imaging train or eyepiece assembly. Also included is a 35 mm 2” extension tube to help you achieve the correct backspacing required for your specific imaging set-up. If you need a different size of extension tube, be sure to check out the selection of extension tubes we carry here at High Point. Also included is a 2" to 1.25" compression ring adapter.
Tons of Inclusions
In addition to the focuser adapters mentioned above, this Apertura 8” Newtonian comes with even more accessories to help elevate your experience! Securing your OTA in place is a pair of felt-lined tube rings. These rings attach to the included Vixen-style dovetail plate, though can be used with Losmandy-style dovetail plates as well. Atop this OTA is a finder bracket for use with the included 8x50 straight-through finderscope. This accessory makes it easy to quickly locate your targets for a more streamlined viewing experience! For the best performance possible, it’s necessary to allow your telescope to cool to ambient temperature in order to avoid air currents within the optical tube. Speeding up this process is a built-in cooling fan! This low-vibration fan is mounted on the primary mirror cell and is powered by eight AA batteries (not included). Thanks to Apertura, you’re set up for success.
