Product Description
Skywatcher Explorer 300PDS Optical Tube Assembly – High-Performance Newtonian Reflector Telescope
The Skywatcher Explorer 300PDS Optical Tube Assembly is a high-quality Newtonian reflector designed for serious astronomers and astrophotographers. With an impressive 305mm primary mirror and a focal length of 1500mm (f/4.9), this telescope is perfect for viewing and photographing deep-sky objects such as galaxies, nebulae, and star clusters with stunning detail.
Key Features & Benefits
- Large 305mm Aperture: The 300PDS offers 44% more light-gathering capacity than 250mm models, allowing for bright, high-contrast views of faint deep-sky objects, making it ideal for advanced stargazing and astrophotography.
- High-Quality Parabolic Primary Mirror: The parabolic design reduces optical aberrations, delivering sharp and clear images across the entire field of view.
- Dual-Speed 10:1 Crayford Focuser: The included 1.25"/2" dual-speed Crayford focuser with a 10:1 ratio provides smooth, precise focusing, essential for both visual observation and photography.
- Optimised for Prime-Focus Photography: The slightly shortened tube design improves performance for prime-focus photography, making this model well-suited for capturing images of celestial objects.
- RAQ Mirror Coating: Both the primary and secondary mirrors are coated with Radiant Aluminium Quartz (RAQ), providing up to 94% reflectivity for enhanced brightness and long-term durability.
- Ultra-Thin Secondary Mirror Supports: The 0.5mm secondary mirror supports minimise diffraction spikes, contributing to clearer, crisper images.
