Player One IR685 1.25" IR Filter S-series 685nm IR Pass Filter for the Moon and Astrophotography
Description:
The S series filter is developed using the process adopted by large factories. It uses high-quality optical glass substrate and multi-layer composite coating process, so it has an excellent optical performance in astrophotography.
This IR685 infrared filter can filter out most of the visible light. It only allows red light and infrared light with a wavelength greater than 685nm to pass through. It can greatly improve the seeing when you are taking photos (because the atmospheric jitter has a slight effect on the longer wavelength of light ). IR685 can be used to photograph the moon. The upgraded IR685 filter uses a double-sided multi-layer composite coating. It will become a practical tool for astronomical photography in your hand!
After a lot of photography by enthusiasts around the world, it was found that IR685 also played a great role when photographing Uranus. It can be used to photograph distinct cloud bands.
