Celestron RASA V2 280 mm (11″)

RASA 11 V2: Revolutionize your approach to Deep Sky astrophotography

Transform your astrophotography experience with Celestron's Rowe-Ackermann Schmidt Astrograph (RASA) 11 V2, an instrument designed to capture awe-inspiring deep-sky images with unprecedented ease. Whether you're using a DSLR or a state-of-the-art astronomical CMOS camera, this telescope offers incredible performance, even for the most demanding astrophotographers.

Exceptional Images in Record Time

• Ultra-fast f/2.2 system: Allows much shorter exposure times than a conventional f/10 system, without compromising resolution.
• Fast system benefits : Fewer equatorial tracking requirements, often without the need for autoguiding.
• Short focal length 620 mm : Ideal for wide-field shots, celestial mosaics or comet hunting. The small pixels of modern cameras make it possible to capture small, distant galaxies.

High Quality Optics

• Optical system with 4 rare-earth glass lenses: Provides sharp images free from aberrations such as coma, field curvature or spurious colors.
• Optimized 43.3 mm image circle: Designed for the widest sensors, with outstanding image quality up to 52 mm diagonal.
• Minimal vintaging : Enjoy uniform images, even with large sensors.

An Ideal Design for Astrophotography

• Multi-coated optical window included: Compatible with imaging filters for optimum results.
• Integrated CGE bars : For attaching accessories such as a fence.

Advanced Technologies for Unmatched Performance

• Ultra-Stable Focus System (USFS): Reduces focus shift and mirror flop, ensuring exceptional stability. Compatible with Celestron focus motor (#94155-A) for precise control.
• Integrated MagLev fan (12V DC) : Accelerates heat-up and ensures optimum ventilation thanks to a dust filter.

An Innovative Heritage

The RASA 11 V2 continues the heritage of Celestron's Schmidt cameras of the 1970s, while incorporating modern technologies to meet the needs of today's astrophotographers. This astrograph is not only ideal for observing, but also for creating celestial mosaics, mapping the sky and carrying out detailed surveys.

Conclusion

The RASA 11 V2 is more than a telescope: it's a revolutionary tool for exploring and capturing the universe with exceptional image quality and simplicity. Take your astrophotography to the next level today.
