• Focal Length: 120mm

  The objective lens diameter is 30mm. The focal length of the scope is 120mm.F4 aperture optics provides a wide field of view which will help to quickly find the target when performing astronomical observations.;

• 1.25-inch & M42*0.75

  The 1.25-inch interface and M42*0.75 male threads allow to connect with SVbony SV305, ZWO, Orion, QYH and other auto guiding cameras.;

• Fully Broadband Multi-Coated

  Fully broadband multi-coated optics means the types of coating on all optical surfaces throughout the entire scope. And fully broadband multi-coated optics decreases surface reflectivity therefore allows greater optical through-put across the entire visible light spectrum, increases the light transmission and delivers bright, clear and high-contrast images.

• Helical Focus Stroke: 45mm

  The 45mm focusing stroke ensures enough focusing range for observing and focus lock ensures a stable focusing. The built-in helical focuser is better for precise focusing of potential guide stars.

• Ultra-mini Optics

  The guide scope is ultra mini and light, and won’t weight your telescope and mount much.;

• High-quality Craftsmanship

  High-level CNC machined & Sandblasting Oxidation

NOTE:

Computer configuration requirements:

1)The configuration of desktop computer is not less than Intel 4 generation i5, and the memory is not less than 4G.
2)Laptop configuration is not less than Intel 6 generation i5, memory is not less than 8g.

2. This SV305 Pro camera is best used with a refractor or reflector telescope mounted on an equatorial mount that can accurately track the motion of the sky. It is not intended for taking images through the eyepiece of a telescope. You may also require additional accessories and filters to get the best results. If you want to use the SV305 pro camera capture images through telescope eyepiece. you need buy an eyepiece projection adapter.

All software and drivers for this camera are available from the manufacturer’s website.

How is SV305 Pro camera?

Here are the testing results from Dr. Steve Wainwright. ( He has been an astronomer since 1967. He taught astronomy at the University of Swansea in D.A.C.E. evening classes for several years, but now, largely retired. For several years he has been working with his partner Nicola on AstroDMx Capture. They do great help for Svbony cameras working with Linux system. Many thanks for Steve and Nicola.)

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.
