Filters & filter wheels

Filters are indispensable in modern astrophotography. Whether you work with a monochrome camera or suffer from light pollution, the right filter makes the difference between a mediocre image and a razor-sharp one. In this category you will find LRGB sets, narrowband filters (such as H-alpha and OIII), UV/IR blockers as well as filter wheels - manual or motorized.

What filters do you find here?

✓ LRGB filters - For natural color reproduction with monochrome cameras
✓ Narrowband filters (Ha, SII, OIII) - For emission nebulae under light-polluted skies
✓ UV/IR-cut filters - Essential in refractors for sharper detail
✓ Filter wheels - For quick filter changes without refocusing

What are you paying attention to?

• Filter size - Usually 1.25″ or 2″, matched to your camera and telescope

• Parfocal design - No refocusing when changing filters

• Filter spacing - The distance from your sensor affects vignetting and sharpness, especially with fast telescopes (f/4 or faster)

✓ Combine with motorized filter wheels for full automation
✓ Our filters are compatible with all ZWO cameras and also usable on other brands via adapters
