Northern lights Finland

Hi. I have a small group on Fb I am trying to get to try this idea for northern lights . I am new to PI but I am willing to learn. Started to write this project up . From install to being a pi sky cam . Anthony.fi/allsky . I will need help with how to”make” the make file. And I will credit this lounge as the inspiration for the beginning of how to get the PI’s started. I have questions like.. can I get 3 or 10 PI’s sending images to my url.? Security? Ways to speed up the night images? Faster memory cards or usb2 or 3? Thank you all for what I have read and the effort involved so far. It’s been an education and a reason to buy an 8mp cam..
