PRODUCT DESCRIPTION
Celestron 11" EdgeHD OTA is more than just an optical tube — it's a deep-sky imaging powerhouse built for advanced astronomers and astro-imagers who demand perfection.
Who should consider this OTA?
- Astrophotographers: Capture ultra-sharp, coma-free images with pinpoint stars edge-to-edge.
- Experienced Observers: Enjoy stunning planetary detail and deep-sky contrast with zero distortion.
- Intermediate & Advanced Users: Ideal for those ready to step into high-performance optics and precise imaging.
Not recommended for:
- First-time telescope users or beginners.
- Those looking for quick terrestrial viewing setups.
- Budget-restricted entry-level shoppers.
The integrated field flattener ensures every part of your frame is crisp — even at the edges. The aplanatic design removes spherical aberration and coma, so you're not just seeing stars... you're resolving them.
With Celestron’s StarBright XLT coatings, faint galaxies and nebulae come alive. More light. More contrast. More detail. Less time stacking exposures. More time enjoying the night sky.
Advanced Engineering Highlights:
- Mirror Support Knobs: Lock the mirror in place and prevent image shift — perfect for long exposures and slewing.
- Vented Tube Design: Rear vents with 95-micron mesh accelerate cooling and keep dust out.
- Fastar Compatibility: Shoot at an ultra-fast f/2 for deep-sky targets with minimal exposure time.
- Enhanced Brightness: More concentrated, contrast-rich imaging with better signal-to-noise ratio.
- CGE Mount Plate: Easily attaches to CGE-style equatorial mounts — ready for your advanced rig.
Pair with: a high-end equatorial mount, autoguiding system, and dedicated astro camera to unleash its full potential. This is your gateway to producing truly publication-worthy astrophotography.
