The Celestron 8 Newtonian Advanced VX Telescope is an excellent entry-level telescope that can grow with you. Its Newtonian optical design is excellent for visual observing & when combined with the Advanced VX mount you will have all the tools necessary for your hobby. The parabolic primary mirror minimises spherical aberration & produces a sharper image near the edge of the field of view. This scope is great for intermediate visual observers, & beginning astroimagers looking for a large aperture with lots of light-gathering power The Advanced VX mount was designed to provide optimum imaging performance for smaller telescopes. This means the smaller telescope can now take advantage of All-Star Polar Alignment & autoguider support. You will be able to track through long exposures using permanently programmable periodic error correction & image across the meridian without doing a meridian flip. This means you can seamlessly image the best part of night sky. The Advanced VX features significantly larger base castings than the previous design, which improves stability under heavier loads. The enhanced motors offer more torque & can handle slight load imbalances with ease. Features
- 8 (200mm) f/5 optical design gives excellent wide field views
- Parabolic primary mirror minimizes spherical aberration to produce a better image
