SV48 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.SV48 fitted with achromatic glass for chromatic correction and good edge-to-edge viewing, offers high transmittance and ensures clear, sharp images.Green FMC lens eliminates false color and increases the light transmission, delivers bright, clears and crisps images even in low-light conditions.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. Product Description

- There are many 1.25\" star diagonals on the market. Many of them have a mediocre mirror quality with 90% reflectivity (10% loss) and a plastic body. The 1.25\" diagonal by SVBONY stands for a high-quality alternative to those cheap parts. It offers excellent image and mechanical quality. There\'s no vignetting over the full 1.25\" field. SV188P features sophisticated, Multi-layered dielectric coatings that provide an astounding 99% reflectivity for maximum view brightness and sharpness.
- SV188P Diagonals provides a comfortable 90-degree viewing orientation when observing the night sky through a refractor. When use the SV188P with Maksutov-Cassegrain (Mak-Cass) or Schmidt-Cassegrain telescope, you need a special adapter.
- Another advantage is the 1.25\" nosepiece barrel is threaded to accept 1.25-Inch filters. Brass lock Screw and Brass Compression Rings feature more precision and prevent barrels or the surface of eyepieces from marring and scratching.

TipswithSVbony
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 needchoose a telescope.For beginner astronomers, a refractor is the betterbeginner telescope for astrophotography.
Designed for Camera photography
Loosenthe screw that fixes the focuser on the telescope, the focuser canrotate 360 degrees.When you use the camera, you don\'t need to unscrewthe camera to adjust the angle.You only need to loosen the screws,adjust the camera angle, and then tighten the screws.
General Notes:
- 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.
Caution:
- Never look directly at the sun with naked eye or with a telescope (unless you have the proper solar filter)
- Adult supervision is recommended when it is for use by children ages under 10 years old
