Featuring a large 310mm aperture and a fast f/3.8 focal ratio, the Sharpstar SCA310 delivers outstanding light-gathering power. This enables much shorter exposure times and higher imaging efficiency in deep-sky astrophotography, revealing intricate structures and rich color even in extremely faint nebulae. As a Cassegrain reflector built around a high-precision parabolic primary mirror. This aspheric surface requires advanced grinding and testing to effectively suppress spherical aberration, producing crisp, pinpoint stars across the field.

Its precisely matched spherical secondary mirror is crafted from fused silica, providing excellent thermal stability. This design allows a long focal length to be folded into a compact optical tube, combining strong performance with convenient portability.

Both primary and secondary mirrors feature enhanced aluminum coatings with over 95% reflectivity, maximizing light throughput and overall optical efficiency.

A built-in 3" triplet coma corrector at the rear of the optical tube, incorporating one ED glass element that effectively corrects coma and field curvature, delivering sharp, round stars from the center to the edges of the image.

Optimized for medium-format imaging, the SCA310 fully illuminates full-frame sensors, achieving near 100% illumination and a flat field even when used with full-frame cameras.

The optical system has been carefully engineered to eliminate the need for additional back focus calculations during imaging, allowing for fast, straightforward focusing and a more streamlined workflow.

The optical tube is constructed from lightweight yet durable carbon fiber, reducing overall weight while offering excellent rigidity and thermal stability. This minimizes focus drift caused by temperature changes, ensuring consistent imaging performance.

A hollow top handle allows for easy transport, while its multi-slot design supports the attachment of various accessories. The bottom is fitted with a 405 mm Losmandy-style dovetail plate, compatible with most equatorial mounts. Fully CNC-machined with a widened, reinforced profile, it provides secure and reliable mounting.

The upgraded 3.5-inch high-rigidity rack-and-pinion focuser offers a 28 mm focusing travel and dual-speed control with a 1:10 fine-focus ratio. Its enhanced load capacity ensures smooth, stable operation even with heavy imaging setups, eliminating slippage.

A front-mounted 360° rotator on the focuser prevents cable tangling during use. At the rear, multiple threaded adapters (M68, M54, and M48) ensure compatibility with a wide range of imaging equipment. The M48 adapter includes an integrated 2-inch filter thread for direct filter installation.

Three integrated cooling fans at the rear of the telescope can be activated before observation to rapidly cool the primary mirror, speeding up thermal stabilization and improving both imaging efficiency and overall user experience.

With the SCA310, you can embark on a deep-sky imaging journey that is efficient, stable, and richly rewarding.
