HQ Pi Cam Notes

I use a HQ Pi Cam for my Allsky setup. One mod I did was to remove the red filter "infrared". This was a simple to do. Note: this will change the colors of trees to look redish and if you have any infrared camers in view the camrea will pick up the infrared. I had to make a block at the dome as I have 2 camera's in view. After the removal of the filter I can just make out the Milky Way. I am in Bortel 7 skys.

    Turns out that Lightning has alot of infered so strikes are not going to show up.

    My settings on the WEB site /allsky/virtualsky.json

    "I see that the overlay on your web site is displaying some Messier objects positions. How did you achieve that ?"

    Look in the /allsky/virtualsky/virtualsky.js for a list of options you can change just add them to the /allsky/virtualsky.json file. I also listed the options below.

    BEFORE you make any changes to the virtualsky.json file BACK IT UP.
