saxon F/5 Coma Corrector for Newtonian Telescope

If you own a fast f/5 Newtonian reflector telescope, you've likely noticed that stars near the edges of your images appear stretched or comet-like rather than perfectly round. This optical issue - called coma aberration - is a common challenge with fast focal ratio telescopes, but it doesn't have to compromise your astrophotography.

Designed exclusively for f/5 Newtonian telescopes, the saxon F/5 Coma Corrector is specifically engineered to eliminate this distortion. Its field-flattening lens works seamlessly with full-frame DSLR and mirrorless cameras without altering your telescope's magnification and ensures your astrophotographs display pin-point star detail from corner to corner. Simply attach it using your camera's T-ring adapter, and you're ready to capture flat-field images that showcase the true beauty of the night sky.

Why This is a Game-Changer:

• True-to-Life Stars: Eliminates the comet-tail distortion (coma) common in fast f/5 optics, delivering a uniform, flat field.

• No Focal Changes: Unlike Barlow lenses or reducers, this corrector works at 1x magnification. You keep your original focal length and light-gathering speed exactly as intended.

• Full-Frame Ready: Designed to illuminate larger sensors, allowing you to take full advantage of DSLR or dedicated astro-cameras without heavy vignetting.

• Visual & Photographic: While it’s a powerhouse for astrophotography, it also works beautifully for visual observers who want edge-to-edge clarity during deep-sky sessions.

What's Included:

• 2" Coma Corrector lens with T-thread (male)
• 2" spacer ring
• 2" eyepiece adapter for visual observations
