    SVBONY SV48P 90mm F5.5 Refractor Telescope RAP Double Speed Focuser 360° Rotator angle

    SV48P 90mm F5.5 Refractor Telescope

    Focal length: 500mm
    Green FMC coated achromatic lens
    2” Rotatable dual speed focuser
    1.71 arc-second resolution
    Compatible with All 1.25”/2” accessories
    Comes with a finderscope base

    Focal Length: 500mm

    SV48P astronomical telescope is of 90mm aperture and 500mm focal length. More lights pass through the 90mm aperture, and you can enjoy a much more clear and bright observation.

    Achromatic Lens

    SV48P fitted with achromatic glass for chromatic correction and good edge-to-edge viewing, offers high transmittance and ensures clear, sharp images.

    Green Fully Multi-coated

    Green FMC lens eliminates false color and increases the light transmission, delivers bright, clears and crisps images even in low-light conditions.

    2” Rotatable Dual Speed Focuser

    The gear ratio of the dual speed 2-inch toothed focuser is 1: 10, which makes it easy to achieve accurate focus. The dual speed focuser can provide two focusing speeds by using a set of co-axial knobs, one for fast focusing and the other for fine focusing.

    Absolute Precision and Smooth Control

    The 90 mm back focus and 360 degree adjustable focuser are sufficient for celestial and terrestrial observations. This focuser offers absolute precision, smooth control and eliminates inherent image-shift and backlash. And it also works well in 90-degree vertical observations .

    1.71 Arc-second Resolution

    The SV48P astronomical telescope can reach 1.71 angular seconds to let you see finer details in observing.

    Compatible with All 1.25”/2” Accessories

    The telescope comes with a 2 inch to 1.25 inch adapter, so that you could also use all your 1.25 or 2 inch accessories with the SV48P telescope.

    Metal Hoop with Dovetail

    SV48P comes with adjustable tube rings and 130mm dovetail which allows it to attach to most telescope mounts and the built-in finders cope bracket allows to attach a finder scope easily.

    General Notes:

    1.Avoid exposing the telescope to sudden temperature changes, as this can result in fogging of the objective lens as moisture condenses on it. If this should happen, place the object lens close, but not too close, to a source of heat and wait for the moisture to evaporate.
    2.Never look directly at the sun with naked eye or with a telescope (unless you have the proper solar filter).
    3.Adult supervision is recommended when it is for use by children younger than 10 years of age.
