Introduction

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 Choose a Suitable Adapter ?

 

How to Use Star Focus Filter(video)?

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), and set the shutter speed to 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 the 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 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.
  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 

 Tips:

  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

Good tool for focus for the price

It’s a little bit tricky to use with short lens but for the price it’s a must have for your night astrophoto sessions…

Great filters

Perfect fit, nice quality and very fine openings so it works on shorter focal length lenses very well. Best way to focus!

Easy and perfect Tool

I´m happy that I have found this Easy Focus - Star Focus Filter.
Very easy to use und helps tremendously to find the right focus for your star shots.

Star focus filter highly recommended!

I picked this up as I'd been having trouble getting pin sharp stars, particularly with longer lenses - might be my eyesight. Either way, once you find a star to focus on, this worked fantastically well and removed any doubt that I'd focused correctly. I've ruined a few Milk Way shots in the past because of slightly out of focus shots, even though I was certain they were sharp at the time. Less guess work with the manual fine tuning = peace of mind. Highly recommended.

Makes focusing an absolute breeze!

One of the trickiest aspects of astrophotography is focusing. Due to the low light we work in, getting perfect focus on every shot can be very hit and miss if you’re relying on your camera’s viewfinder or ‘live view’ display. Certainly for me, I really struggled to get perfect focus, often resulting in out of focus blurred shots.

Having read a number of articles about the so-called 'Bahtinov Mask’ which uses optical diffraction to align three ‘spike’ lines to achieve perfect focus. Using your camera’s ‘live view’ display to zoom in on a star, all you have to do is to adjust your focus until the central ‘spike’ sits perfectly between the two outer spikes. It really is that easy! I personally then lock down the zoom ring on my lens using sticky tape before removing the filter. You’re now ready to start shooting beautiful sharp images :-)

The MoveShootMove Star Focus filter fits to any lens with a 82mm screw thread. I purchased mine with an additional 77mm adaptor which comes in very handy if you want to use the filter with lenses like the 70-200mm, 24-70mm or 16-35mm wide angle. Surprisingly, MoveShootMove don’t offer a 95mm adaptor but I managed to pick one of these up on Amazon.

All in all, I would not hesitate to recommend the Star Focus Filter. If you struggle to achieve perfect focus then buy one today - this thing is a must.

Star Focus Filter

I received my Star Focus Filter several weeks ago. I found it to be be excellent on zoom lenses but not so good on wide angle lenses. Wide angle lenses the image star is too small to get an accurate focus. If there is something else in the sky, eg a bigger object it would pay to focus on that then go to your subject.

Super useful filter

This star focus filter makes focus on stars a breeze. Super useful. Everything this company makes are well thought out designs.

It fits the lens with the adaptor, quality seems good. Looking forward to try it.
