Skywatcher Explorer 300P-DS 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.

Specifications

  • Aperture: 305mm
  • Focal Length: 1500mm (f/4.9)
  • Magnifications (with supplied eyepiece): x53.5

  • Please contact us before sending anything back so we can advise on the safest way

What happens if I don't like it?

We always want you to be happy with your purchase — so if you’re unsure, please ask us first. We’re always happy to give honest advice before you buy.

If the product arrives and you simply decide it isn’t for you, you can usually return it within the cooling-off period — as long as it’s unused, in perfect condition, and returned with all original packaging and accessories.

Because telescopes and optical equipment are large, delicate and expensive to ship, you’ll need to cover the cost of sending it back, and if we originally subsidised delivery, we may deduct our outbound shipping costs from your refund.

We’re a small specialist business, and unnecessary returns genuinely hurt us — so if you’re unsure at all, please talk to us first. We’d rather help you choose the right item than process a return.

How fast is shipping?

We aim to ship in-stock items as quickly as possible.

  • Most in-stock orders dispatch within 1–2 working days
  • Delivery usually takes 1–3 working days after dispatch (UK mainland)
  • Heavier / oversized items and special orders may take a little longer

You’ll receive tracking details as soon as your order is on its way.

Astronomy equipment often requires specialist packing and trusted couriers — we do this to keep your gear safe, not to slow things down. If you need something urgently, just ask and we’ll do our best.
