Vai al moduloOptolong L-PRO 2" (50.8 mm) – Light Pollution Filter
The Optolong L-PRO 2" is designed to selectively reduce light pollution caused by artificial lighting while preserving the natural color balance of celestial objects. It is a broadband filter, making it especially suitable for observing and imaging emission nebulae.
Unlike narrowband filters, the L-PRO allows nearly all useful wavelengths to pass through while blocking only the unwanted bands. This design makes it compatible even with smaller telescopes and highly effective in areas affected by light pollution, such as cities, suburbs, or rural locations.
Main Advantages
- Targeted light pollution reduction – improves night sky contrast.
- Ideal for emission nebulae – without unnatural color shifts.
- Compatible with small telescopes thanks to its wide and balanced transmission.
- Perfect for astrophotography – works with DSLR, CCD, and CMOS cameras (color and mono).
- Effective in urban, suburban, and rural skies.
