SCA260 V2

Telescope SCA260 v2 - Astrographe Cassegrain Asphérique

The SCA260 v2 telescope is a state-of-the-art astrograph designed to provide a high-quality observing and imaging experience for amateur and professional astronomers alike. Built around advanced technology, it stands out for its optical performance, durability and elegant design.

Exceptional optical characteristics

• Mirror primary aspherical : Made from PZ33 (similar to Pyrex glass) for superior thermal stability and consistently sharp images.
• Opening diameter : 260 mm
• Focal length / Focal ratio : 1300 mm / f/5
• Corrector : Three-element lens with air space for full field and reduced vignetting.

Performance and precision

The SCA260 v2 features improved aluminum coatings on its primary and secondary mirrors, ensuring a reflectivity level of over 95 %. This high light transmission guarantees bright, high-contrast images. The simplified optical axis requires only adjustment of the secondary mirror tie-rod, optimizing use of the 3" corrector for full-frame imaging and vignetting control.

Robust, lightweight design

• Carbon fiber tube : Lightweight and robust for easy transport and handling.
• Tube weight : 14.5 kg for a diameter of 304 mm, ideal for a personal observatory or on the move.

Focuser and Versatile Accessories

• 3.35-inch focuser: With a 50 mm stroke, it offers maximum flexibility when adding accessories and guarantees smooth, stable operation.
• Multiple threads : M68X1, M54 × 0.75 and M48 × 0.75, as well as an integrated 2" filter thread, for extended compatibility with various accessories.
• Back-focus : Standard 55 mm from the base of the mounting thread for quick and easy connection.

Versatile mounting and accessories

• Versatile handle: Easy handling and mounting on a variety of equatorial mounts.
• Vixen-type dovetail : For easy, safe assembly.

Technical details

• Minor axis of secondary mirror : 120 mm
• Image circle : 80 mm
• Resolution: 0.46 arcseconds
• Limiting visual magnitude : 13.8
• M48 focal length : 70 mm from focal plane

Conclusion

The SCA260 v2 telescope is the fruit of multiple optimizations to offer optimum image quality and ergonomics tailored to the needs of astrophotographers. Its combination of exceptional optical performance, top-of-the-range materials and precision engineering makes it a durable and elegant instrument, capable of satisfying the demands of observation and imaging enthusiasts.
