RASA Telescopes
RASA telescopes (Rowe-Ackermann Schmidt Astrograph) are instruments designed exclusively for astrophotography. Thanks to their ultra-fast focal ratios and fully corrected image field, they enable highly detailed deep-sky images with significantly reduced exposure times.
- Ideal for: nebulae, galaxies and wide-field deep-sky imaging
- Main strengths: ultra-fast optics, corrected field, maximum imaging efficiency
- Practical note: not designed for visual observing

What is a RASA telescope?
The RASA (Rowe-Ackermann Schmidt Astrograph) is an astrograph based on a modified Schmidt optical design, optimized specifically for astrophotography. The camera is mounted at the front, and the optical system is engineered to deliver a fully corrected field across large sensors.
What it is best suited for
- Deep-sky astrophotography: extended nebulae, H-alpha regions, galaxies and wide star fields.
- Narrowband imaging: enabled by the extremely fast optical system.
- Advanced setups: intended for experienced imagers with suitable mounts.
Why choose a RASA
- Very low focal ratio: dramatically reduces exposure times.
- Corrected image field: sharp, pinpoint stars across the entire sensor.
- High optical quality: purpose-built for astronomical imaging.
- Camera compatibility: optimized for dedicated astronomy cameras.
Frequently asked questions (FAQ)
Can a RASA be used for visual observing?
No. RASA telescopes are designed exclusively for astrophotography and do not support eyepiece use.
Is a RASA suitable for beginners?
It is recommended for users with prior astrophotography experience and familiarity with cameras, filters and mounts.
What mount is required?
A stable and precise equatorial mount is required, capable of safely supporting the tube and imaging accessories.
