• Global Shutter: High frame rate of 120 frames per second;
• Large Pixel: SC432M pixels are 9μm x 9μm for more detailed images;
• 1.1-inch Frame: Larger shooting area for less post-processing;
• Fan Cooling: Longer exposures reduce noise for better image quality;
• HCG: Turning on the HCG mode at a gain value of 140 dramatically lowers the readout noise while maintaining high dynamic range, avoiding celestial drag.

This telescope bundle set includes SVBONY refractor OTA and the SV229 solar eclipse filter metal cap. The SV229 is an ideal choice for viewing the sun, and it conforms the standard ISO 12312-2: 2015. You can use it with confidence. It is also suitable for daily solar observations. It is worth to mention that, the SV229 solar filter metal cap is compatible with most of our telescopes and other brand refractors. 

• The SV216 Barlow lens adopts a 4-piece telecentric design, which effectively prolongs the focal length of the primary mirror without introducing chromatic aberration and vignetting problems that bother users. Offers excellent spherical aberration control, resulting in a flatter field of view than standard Barlow lens;
• The magnification of the SV216 Barlow lens is constant at 2 times. the 4-piece design of the Barlow lens and the optimized optical structure ensure that the magnification factor of the Barlow lens remains unchanged no matter where the Barlow lens is installed in the optical system;
• SV216 2x Barlow lens adopts 3 screws design and coaxial locking device. Improving the concentricity of the optical axis of the system can significantly improve the quality of captured images;
• The 4 lenses of the SV216 Barlow lens are fully multi-layer enhanced coating, which makes the picture bright and sharp. The edges of the lens are blackened to eliminate internal light scatter to maximize image contrast;
• The low magnification eyepiece is matched with the SV216 telecentric 2x 4-element Barlow lens, which can enjoy the magnification effect of the high magnification eyepiece while the eye relief distance is still within the comfortable observation range of the human eye.

When total solar or partial eclipse happening, it can greatly shorten the searching time using this solar finder scope, you can observe the real-time location of it when the sun moving.
