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.

Q:What are the outstanding features of the upgraded sv48p?
A:
Toothed focusing knob
Dual speed still, but this time you will find the toothed knob on the scope just you did on our star product SV503. The touch matters in our opinion. These pairs of toothed focusing knobs would make you feel more pleased when you view the night sky with naked eyes. The targets have been located but somehow we just couldn’t make it clear, that might be the last thing we wish to happen in this hobby. So we keep the dual-speed focusing system which makes the whole process easier and smoother and we truly believe that you would love it.
Comfortable damping
We want to achieve a good balance between damping and smoothness with this tiny brass focus plate. So now, a 13mm brass plate under the focusing tube, provides comfortable damping to secure the process of focusing stable and accurate, which means deviation or shaking of the focusing tube, or the inconsistency of the hand feel during the whole operation of the focusing will not be the pain again.
360 rotatable R&P focuser
A rotatable focuser would greatly help you get just the right position for your camera or diagonal without touching multiple screws which could be pretty annoying to the final image. Just loosen the knob on the tube a little bit then you could just rotate the whole focuser, simple and clean.
Mounting rings with a 130mm dovetail plate
A longer dovetail plate than the original SV48 which has a 100mm dovetail plate gives you more space for the mounting, with the fine-made mounting rings together making sure your telescope is steady.
Q：Hello, does this only bring the telescope or does it have other accessories? Can I use it directly after buying it? Do I need to buy other accessories?
A:Package includes SV48P 90500 Astronomical Telescope OTA,2″ -1.25″ Adapter,Finder Scope Bracket,Lens Cover,1.25″ Dust Cover,130mm Dovetail Mounting Plate with Tube Ring
No included diagonal, eyepieces and a tripod etc.
Q：The description has two different weights how much does it actually weigh？
A：7.73 pounds
Q：What type of glass is used in the objective?
A：Fully multil green coated lens; fitted with achromatic glass for good edge-to-edge viewing; fully multi green coated lens maximize light transmission eliminating false color.
Q：are the rings felt lined?
A：Sorry it doesn’t, the bracket is fixed on the lens barrel with screws and is detachable.
Q：Is the metal loop telescope holder removable, if is is, how do you remove it?
A：Yes, you can remove it by turning the screws on the bottom of the stand.
Q：How to get started with Astrophotography?
A: Firstly, you need choose a telescope.For beginner astronomers, a refractor is the better beginner telescope for astrophotography.
Designed for Camera photography
Loosen the screw that fixes the focuser on the telescope, the focuser can rotate 360 degrees.When you use the camera, you don’t need to unscrew the camera to adjust the angle.You only need to loosen the screws, adjust the camera angle, and then tighten the screws.
