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.
Note: Star Focus Filter can work with other lenses with the help of camera adapter rings.
Does it work with zoom lens?
Yes, it's ok for zoom lens. The longer the focus length the better the performance.
What is the shortest, (widest) focal length this will work with? 14 MM, 20MM, 35MM, 50MM?
Yes, this focus filter can work well with all the wide lenses mentioned above, it will perform better on zoom lenses. The longer the focal length, the better the performance.
I have a Nikon 24-70 that has an 82mm thread for filters. Does the 82mm have a thread to fit my lens?
Yes, the filter has the thread to fit into the lenses.
Using the Star Focus Filter:
Method 1
- Mount the Star Focus Filter onto your camera.
- Turn on the live view mode, adjust the ISO to the biggest (ISO 1600 or above), and set the shutter speed to 10s or more.
- Adjust the frame and make sure the bright star or light source is in the middle of the frame. It is recommended that you look for a bright star of magnitude 1 to focus on.
- Magnify the frame and adjust the focusing rings at the same time until three fine spike lines show out in the frame.
- Rotate the focusing ring to make the three spikes intersect at one point. This the when the precise focus is achieved.
Method 2
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.
- 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.
- Adjust the focus rings to get an infinity focus
- Set the high ISO and short exposure (several seconds), and take one testing shot
- heck the three spike lines in the frame, if the central spike is closing to the left, screw the focus ring to the right. If the central spike is closing to the right, screw the focus ring to the left.
- Take a second testing shot, and repeat step 4 until three spikes intersect at one point. Then a precise focus is achieved.
Note: Hand holding the filter, then it can work with the lens without the adapter
Tips:
- 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
- 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
- Do not place it in high temperature environment
