Whether you are capturing the vibrant colors of emission nebulae with our narrowband filters or enhancing contrast in light-polluted urban environments with our multiband filters, SVBONY filters are engineered to provide exceptional performance. Our broadband filters allow for versatile usage, making them ideal for general stargazing and imaging across different celestial objects. Read More
Astronomical filters are the preferred method to enhance contrast. These filters work by selectively transmitting light at certain wavelengths while blocking others. There are three main types of telescope filters: nebula filters for deep-sky observation, planetary filters, and solar filters. It's important to note that astronomy filters reduce the amount of light passing through the telescope, resulting in dimmer overall images. Read More
Redshift is an interesting astronomical phenomenon. In the visible light band, it is manifested as the spectral line moving a certain distance toward the red end, that is, the wavelength becomes longer and the frequency decreases. , this is the redshift, and the movement of celestial bodies and the prediction of their patterns are inseparable from the study of the redshift phenomenon.
