2SVBONYSVBONY SV48P Telescope for Adults High Powered, 102mm Large Aperture F6.5 Refractor OTA for Adults Beginner Astronomer, Astronomical Telescope for Observation of Deep Space Celestial Objective
Main highlights- 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; very useful for taking wide-angle celestial photos
- Widely used; the refractor telescope can be used in multiple scenarios; such as observinging the moon; nebulae; celestial bodies; etc; the excellent optical performance of the telescope can produce clear images
- The SVBONY SV48P is a 102mm f/6.5 achromatic refractor with fully multi-coated optics; a 2.5-inch dual-speed focuser and a 360-degree rotatable design; weighing just 7 lbs, it’s a great option for wide-field astrophotography; especially with a field flattener
- Objective lens cleanliness; dust on the objective lens will cause reflection of light; thereby reducing transmittance; maintaining cleanliness minimizes these interferences and improves the brightness and clarity of the image
- Integral hoopd; 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
- Fully multi-coated lens; uses superior optics to provide clear and realistic views; designed with fully multi-layer coating; more realistic colours for maximum eye protection
- 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
- 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; product does not include field rotator, good astronomical observations can be achieved by choosing the right eyepiece; effective tracking, and post-processing
- Combinations; the refractor telescope can be used with SV705CC planetary camera to assist photography; and can be used with SV231 chromatic aberration correction filters to control chromatic aberration levels
- AR anti-reflective coating; it can reduce reflection and increase transmittance; improving the brightness; clarity and contrast of images; thereby providing a better visual experience
