Svbony sv10 is a fixed-focus binoculars of 8x25 ,no need to focus and easy to carry ,  Just take it to view whatever you like!

This SV503 telescope combination set includes a 102mm ED F7 refractor telescope, a SV223 90 degree diagonal mirror, a SV182 6x30 right-angle correct-image optical finder scope, a SV211 203mm saddle handle bar and a universal dovetail base. It is a suitable telescope visual set for astronomy.

This SV503 Telescope Set is suitable for astronomical visual observation.

• 90 mm aperture; 500mm focal length; compared with 70mm and 80mm; 90mm telescope has more light input and a wider field of view; observe the moon and deep space; which is very suitable for astronomy beginners
• Double speed focuser; the 2 inches rotatable double speed focuser; gear ratio of 1:10; precise adjustability for smooth operation
• The focusing mount with metal interface has higher interface accuracy; guarantees the parallelism of the optical axis; and enhances the observation experience
• 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
• 360 degrees rotation; convenient for photographic composition and visual observation; loosen the screw; the focus can be rotated 360 degrees; you can achieve astronomical shooting

• SV209 0.8X focal reducer/field flattener is designed specifically for prime focus astrophotography with the SVBONY SV550 122mm f/7 apo refractor;
• It can correct the defect of field curvature of the user's shooting target; improve the imaging quality and shooting efficiency of the edge of the field of view;
• It converts the 854mm focal length f/7 refractor into a 683.2mm f/5.6 system for faster and wider field astronomical and terrestrial photography;
• In addition to reducing the focal length of the telescope and thereby increasing the photographic speed, the flattens the normal field curvature inherent in refractors. This provides images that are sharply focused out to the corners of DSLR and CCD imaging chips;
• SV209 0.8x reducer has a metric 63x1 thread; the telescope reducer flattener screws into the focuser to ensure a secure connection.

Set Includes:

• SV503 70ED F6 refractor, SKU: F9359A
• SV182 6x30 Straight-Through Metal Finderscope, SKU: W9141A
• SV158 75mm Extension Tube 2 inch, SKU: W9119A
• Universal Dovetail Slots, SKU: W2370A

Note: The SV503 70ed is designed with f/6 focus ratio. When reducing the focus further, the image quality will not be guaranteed. This is why 0.8x flat field is not available. If you need flat field for telescope, we suggest choosing SV503 80 f/7 refractor.

• Svbony SV410 is very small, only one palm size, so you can put it in your backpack, pockets, wherever you want, it's very convenient;
• Svbony 9-27x56mm has ED glass, which can provide exceptional clarity, decreases glare and ghosting effectively.
• Comfortable 45° viewing angle allows you to watch both the sky and the earth;
  Includes soft carrying case, lens cloth, and lens covers, which can protect your spotting scope and achieve a long-term use;
• Suitable for birding, view target shooting and sporting event.

Note: Act20 HD action camera and SV410 mini telescope are independent devices, and it is more affordable to buy them together.

• 102mm large aperture; large objective lens refractor telescope; high resolution; good light collecting ability; f/6.5 focal ratio; imaging brighter;
• 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;
• 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;
• Integral hoopd; the tube rings make the telescope more stable and avoid wobbling; and provide a stable support to keep the optical components of the telescope stable relative to each other;
• Easy to assemble and use; the telescope is designed to be user-friendly; it can be set up quickly without additional tools; you can find a lot of fun in assembling.
