 +===== How to use a Bahtinov mask to check focus ===== 
 + 
 +If your Bahtinov mask was made for the Seestar then it should fit into the lens opening in the same way as the orange solar filter. 
 +  
 +But before you place it over the lens do two things:
  
-Then read the tutorial section titled "Find & Shoot Objects" and follow the instructions to find a field of view that contains one or more bright stars more or less centered in the field of view.+1. Tap the "Tutorial" icon on the Home screen and then look at the Turn On Manual Focus tutorial.
  
 Then tap the AF icon at the lower right side of the screen. Once auto focus says that it has finished, check on the left, lower side of the screen. You should see the "Manual Focus" panel. Take note of value displayed there. This is the proper focus setting that the Seestar has determine with it's autofocus algorithm. Moon, Solar, Planetary, and Scenery each may have a different focus point. Then tap the AF icon at the lower right side of the screen.

-Next, carefully insert the Bahtinov focus mask in front of the Seestar lens and observe that now the individual stars shown on your phone or tablet will appear to have an X across them. The Bahtinov focus mask causes diffraction spikes to form from the star images. In addition there will be a diffraction spike that splits the X somewhere.+2. Next, carefully insert the Bahtinov focus mask in front of the Seestar lens. Don't get fingerprints on the lens! Once installed observe that the individual stars shown on your phone or tablet will appear to have an X across them. The Bahtinov focus mask causes diffraction spikes to form from the star images. In addition there will be a spike that splits the X somewhere.
  
-The goal is to center the diffraction spike so it crosses exactly in the center of the X. If if it doesn't, use the manual focus panel buttons to adjust the focus so that the spike is perfectly centered across the X.--- //[[murrayfoster3@gmail.com|Murray Foster]] 2024/06/25 10:59//+The goal is to center the diffraction spike so it crosses exactly in the center of the X.

 A typical workflow will start with an overall brightness adjustment perhaps with help from the curve tool to brighten just parts of the image. Gradients, if any, will typically be revealed so fix that and then use the AI Denoise to remove grain. Some images have so many stars they distract from your target, so you can use the AI Star tool to reduce or even remove them. Finally, you may want to tweak the color and saturation before saving your image to the Apple Photos library. A typical workflow will start with an overall brightness adjustment perhaps with help from the curve tool to brighten just parts of the image.
