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

Great filter kit

This is the Bahtinov focus filter with several adapters for different lens. It works great the the selection for different lens sizes is perfect for me to focus then remove to take star photos

Star Focus Filter

Works well and makes manual focusing easy. The only problem I have is that the stepping rings (I bought the complete set) are prone to ‘bind’. Hence knocking off one star in the rating. A box to put it all in would be very useful.

Useful stuff

Easy focus star filter

The filter arrived in good time & looks good quality although I havent used it yet. My only complaint is it isn't supplied in a box to store it in, fortunately I had a spare Nisi filter box.

MSM Bahtinov Masks for camera are a game changer for focusing at night!

We have Bahtinov masks for our telescopes but when I saw this for a camera with adapters for different size lenses I knew they would be the perfect gift for my husband. He struggles to get the stars in focus for Milky Way and Comet photos but these do a wonderful job of making them look crisp and clean! Well worth the money. I bought the variant with a full set of adapters and it works with all types of lenses. Wonderful product and well executed.

Star Focus Filter

So happy I bought this, at my age the eyesight isn't that good even using the live screen but with the Star Focus Filter I can easily adjust focus now.

Easy focus star filter - really is

Move Shoot Move have brought long exposure Astro photography to a much wider audience thanks to their combination of excellent value products and for their ease of use. As someone who now uses the Shoot Move Shoot Nomad all the time the acquiring of the Easy Focus filter was a great addition to speed up focusing of stars. It is very straightforward to use and works brilliantly on longer focal length lenses. Being a screw on filter it can be quickly attached and then removed. If you struggle to focus on stars and are using longer focal lengths then this is a great purchase. Highly recommended.
