How to Use Star Focus Filter(video)
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
-
Mount the Star Focus Filter onto your camera.
-
Adjust the focus rings to get an infinity focus
-
Set the high ISO and short exposure (several seconds), and take one testing shot
-
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.
-
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

I bought the star focus filter. The product is very well made and is very helpful to focus on the stars. It is a must for astrophotography. Customer support is very prompt and helpful. I highly recommend this product and this company. I will be looking at other items they make and I'm sure I'll buy more from them.
The filter worked exactly as I had seen on various YouTube videos. Really helped with stars in the deep sky. If you want to make manual focusing a cinch, then get these filters. They are especially helpful if you’re farsighted and have to wear corrective lenses to see objects up close like on a live view screen if a DSLR. This filter will take the guesswork out of whether you’re seeing a truly sharp object or not. Great product and I would certainly but it again.
The Star Focus Filter is really a help whilst focussing on the stars. Not an almost but a yes sharp result 👍
Seems to me Move-Shoot-Move always get the point:
Very easy to use and high quality per price product.
This is one example, easy to use, very sharp focus in 99% of focal leghts!
So I bought the 100x100mm filter to use on multiple lenses with a filter holder. It worked so well. I was using it to find the E3 Comet and focused on the stars around it and it worked out great! Easy to use but make sure you digital zoom for focus magnifier so you can see it better. Really good buy for my gear.

This filter works really well. Bright stars show up in live view nicely. Dimmer stars you will need to take a test shot and view the photo. Great addition to my setup.
Works great on my 200mm telephoto lens. Quality on these are nice too. The adopters fit my lenses perfectly.
