I was going to put this on my HVL Photography club Facebook page, but they all follow me, so putting it on my main feed so others can see this tip as well.  And also including here on my blog.

For the Christmas Star photo opportunity on 12/21 when Juniper and Saturn are lined up there is a setting you will want on your camera to accentuate the star pattern.  You can search the Internet or just follow this link to read more.

 Set your camera on Aperture Priority or Manual Mode and ensure the F-Stop of 8.0 or higher. If you see photos that have star patterns from the lights it is because the F-Stop is at 8.0 or higher.

 Take some practice night shots with a high F-Stop and you will see what I mean.
