The L-eNhance is a tri band filter and the ideal choice for enhanced light pollution suppression. It allows astrophotos to be taken of narroband emission objects in O-III, H-Beta and H-Alpha lines out of the city.
- Professional photographic filter for astronomy
- Improves deep sky emission nebula photography
- Best choice for enhanced light pollution suppression
- For taking pictures also from highly lightpolluted areas
- High Transmission for O-III, H-Beta and H-Alpha lines
- Doesn't require very large or extremely expensive telescopes
- CMOS cameras can deliver images like monochrome cameras
- Balanced colour for a natural image result
- Filter DIA: 1.25inch/31.7mm, Connecting tread: M28x0.6mm
- Multi-layer anti-reflection coatings for highest image contrast

Product information "EXPLORE SCIENTIFIC OPTOLONG 1.25'' L-eNhance Deep-Sky Light Pollution Filter"
The relentless spread or urbanization and its associated light pollution have become a growing problem for all amateur astro photographers. The current solutions to the problem can be expensive and might include the purchase of a monochrome camera, several types of narrowband filters and a filter wheel. Especially with inexpensive newtonian telescopes, double-lens ED refractors or even achromats, the L-eNhance filters open up completely new possibilities for the capture of high-class astronomical images even out of the light polluted city. CMOS cameras can deliver images like monochrome cameras. This new generation of filters makes it possible to take amazing astrophotos directly from the light-polluted city with all its artificial light sources. The narrow bandpass for the wavelengths of O-III, H-Beta and H-Alpha and the almost complete attenuation of the interfering light sources of these new filters make this an ideal solution.

- General safety instructions DANGER Risk of eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device especially the lenses to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
- Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
- Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
- Do not expose the device to high temperatures.
