Samsung G8 astro camera

The newer smart phones now have greater control over various camera setting, like ISO, EXP, and more importantly duration. These now mega pixel cameras can show wide field views of the sky.
Like these.

These are approximately 70 x 50 degrees FOV, or a 45 degree radial from the center of the field.
So what is it good for, well I can see omega centauri and stars down to mag 6. It should catch bright satellites and perchance a bright meteor.

The second phase of this project, was to boggee into the phone case a Star Analyzer 100 grating.
Like this,
[ phone case]
To do this,

While still working on getting focus, the results look like this,
[acrux spectrum]
[scorpius spectrun]

So the next steps is,
 to refine focus,
 try out on a guided mount for better noise reduction,

A Quick how to here......

Then figure out how many phones it take to cover the whole sky.
An lastly figure out how to make the phone tweet a picture on a detected brightness change in any FOV. As it could be plane, satellite, or meteor.....the tweeteor project ...8)
