Portable Triplet Refractor Telescope for Deep Sky Astrophotography and Visual, Adults

The SV550 APO Triplet refractor, with its 80mm aperture and fast f/6 focal ratio, is a great travel telescope for both observation and astrophotography. The telescope features a triplet apochromatic optics structure, which includes one piece of S-FPL51 low-dispersion ED glass and two pieces of correction glass. This design significantly improves the image quality, reducing the blue-edge chromatic aberration problem often seen in single-ED structure imaging.

The air-spaced triple optical design virtually eliminates chromatic aberration, resulting in bright, high-contrast images that are perfect for exploring galaxies with improved graphic clarity. The telescope also includes a 2.5-inch magnesium alloy dual-speed toothed focus mount (1:10), which reduces vignetting on full-frame cameras and decreases the weight of the support platform.

To achieve the ultimate pursuit of extinction, the SV550 APO Triplet employs extreme extinction measures. Multiple light barriers are designed inside the focusing seat and the inner wall of the lens barrel, with four extinction bars specifically engineered to eliminate any stray light interference.

In terms of accessories, the SV209 Field Flattener, SV210 Camera Angle Adjust, SV405CC Telescope Camera, SV198 Guide Scope, SV211 Dovetail Base, SV212 Telescope Bag, and 2-inch CLS Filter are available for purchase. These accessories can further enhance the telescope's capabilities for both visual and astrophotography applications.

The SV550 APO Triplet refractor is suitable for beginner and intermediate astronomy enthusiasts, allowing them to observe and photograph the lunar surface, as well as deep-sky objects. With a resolution of 1.45 arc seconds, this telescope is a powerful tool for exploring the wonders of the night sky.
