• ① Star Focus Filter is used to work with cameras to achieve precise focus on the stars. Focusing a camera lens in the dark is always a difficult thing in astrophotography. Through the Bahtinov Mask on the filter, Star Focus Filter can help the camera get an accurate focus on stars.
• ② It will need to position the bright star in the middle of the frame, choosing the bright star of magnitude 1 or close to the magnitude 1. For the wide lenses, please turn the aperture to the biggest.
• ③ The filter is not wear-resistant, please store it in a filter case after use. If there is dust or oil, please use an air blower and neutral detergent to remove them. Please do not place it in high temperature environment.
• ④ If you can't find a brighter star or the lens aperture is too small, you can take several testing pictures to get the focus.
