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.

How to Use Star Focus Filter

Method 1

  1. Mount the Star Focus Filter onto your camera.
  1. Turn on the live view mode, adjust the ISO to the biggest (ISO 1600 or above), snd set the shutter speed to be 10s or more.
  1. 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.
  1. Magnify the frame and adjust focusing rings at the same time until three fine spike lines show out in the frame.
  1. Rotate the focusing ring to make the three spikes intersect at one point. This the when 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.
  1. Mount the Star Focus Filter onto your camera.
  1. Adjust the focus rings to get an infinity focus
  1. Set the high ISO and short exposure (several seconds), and take one testing shot
  1. Check 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.
  1. 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 


  1. 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
  1. For the wide lenses, please turn the aperture to the biggest
  1. 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
  1. Do not place it in high temperature environment

Star Focus Filter

I tried this at 14mm - 24mm and did not see the pattern, but have heard other brands generally have this problems also.
at 70mm and above worked great, did not have lens handy to determine where it started working between 24 and 70mm

Pierre Bouvier (Québec, CA)

I have always struggled to achieve accurate focusing when taking photos of the night sky. So I decided to purchase the Move-Shoot-Move Star Focus Filter and give it a try.
Without doubt, I am delighted how this filter has helped me achieve super fast, precisely accurate star focusing.
The Move-Shoot-Move Star Focus Filter is truly amazing !

If you are an astrophotographer and want the fastest ‘Star Focusing’ method or technique, go ahead and treat yourself, you will be surprised how easy it is to get pin sharp star focusing, using this awesome devise.

It is worth every penny !

Bathinov mask & adapter

The mask is working very well.
I ordered it with the complete set of adapter rings because my lenses have different diameters.
I cannot give 5⭐ because I think one fundamental ring is missing: the 2"; the mask is more and more important with longer FL and one of the most common long lens for MSM is the OPT TPO ultrawide (or the Askar version) and this lens is 2".

Stephen Pidgeon (Perth, AU)
New Star focus filter

Way more accurate than focus on a bright star. Would definitely recommend it.

bryan dillon (Wrexham, GB)
Star focus filter

Item made it in good time through the post. Already fitted to the resize adaptor.
Screwed onto my lens for the first outing whilst under darkness and the stars. Focused was really easy down to 24mm. Below that I struggled to see the Bahtinov effect on the live view. Wanting to focus at 24mm it was super easy.
Especially when you remember to remove it afterwards. Would recommend to anyone struggling to focus at night.
