Svbony SV48P 102mm F6.5 Refractor Telescope with Dual-Speed Focuser - F9341C

• 102mm large aperture; large objective lens refractor telescope; high resolution; good light collecting ability; f/6.5 focal ratio; imaging brighter;
• f/6.5 short focal ratio; larger field of view; can collect more light; the image is brighter; and the observation target is clearer and easier to observe;
• Dual-speed focusing; fast focus allows you to quickly move the focus wheel to roughly focus on your target; while slow focus adjusts focus more finely for optimal image clarity;
• The tube rings make the telescope more stable and avoid wobbling; and provide a stable support to keep the optical components of the telescope stable relative to each other;
• Easy to assemble and use; the telescope is designed to be user-friendly; it can be set up quickly without additional tools; you can find a lot of fun in assembling.

Note: The main lens have been corrected completely.

 

102mm Large Aperture

The SV48P refractor telescopes for astronomy are equipped with a 102mm large aperture. When watchers observe the planet or galaxy, it is helpful to enhance the brightness of observation and increase the observation efficiency. Also, large objective lens refractor telescope is designed with high resolution; good light collecting ability; f/6.5 focal ratio; imaging brighter.

F/6.5 Short Focal Ratio

The focal ratio of the refractor telescope is f/6.5. Compared with the fast f/4 to f/5 ratio, and slow f/11 to f/15, middle f/6.5 can provide larger field of view, collect more light and brighter image. The observation target is clearer and easier to observe; very useful for taking wide-angle celestial photos and is more suitable for observing nebulae and galaxies.

Dual-speed Focusing

The fast focus allows you to quickly move the focus wheel to roughly focus on your target; while slow focus adjusts focus more finely for optimal image clarity. Just to experience the smooth operation and precise adjustability.

Reduce light leakage

This design can reduce light leakage and provide clearer vision.

Fully Multi-coated Lens

The SV48P achromatic telescope uses superior optics to provide clear and realistic views; designed with fully multi-layer coating; more realistic colours for maximum eye protection.

Use with SV231 Chromatic Aberration Correction Filter 

Chromatic aberration control can ensure stunningly sharp and realistic images. 

Visual Observing Combination

You can use the refractor telescope with diagonal, eyepiece and finder scope to observe the planet.

Integral Tube Rings

The tube rings make the astronomical telescope more stable and avoid wobbling; and provide a stable support to keep the optical components of the telescope stable relative to each other.
