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.

  • Use these instructions Found Here to remove the filter.

    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.
