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
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
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
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
SV135 7 mm to 21mm adjustable focal length;SV135 7-21mm zoom eyepiece equivalent to multiple eyepieces ;obtain higher magnification with short focal length;It could bring you a better observation experience in a comfortable situation with high-contrast imaging
18mm - 16.3mm comfortable eye relief; especially for eyeglass wearers ;designed primarily for viewing landscapes and astronomical observations of lunar surfaces; planets; nebulae; clusters; and diffuse nebulae
Positive image optical viewfinder provides stargazers with a bright; clear image through the viewfinder for easy aiming anywhere in the sky
The 90% reflectivity flat mirror can reduce light loss and make the field of view clearer and sharper
Standard 1.25 inches diameter can be used with 1.25 inches telescope accessories such as eyepieces and barlow lens
