The Solarcan Puck is a great little reusable solargraphy camera. It has a relatively wide aperture (f/90), so it can create a decent image in a single day. The limitation is that it has (for a camera of this type) a relatively narrow field of view - about 120 degrees. This means that if you have it mounted vertically, you are going to be able to record angles up to 60 degrees above the horizon. This is fine if you are above about 50 degrees latitude. At about 50 degrees, the sun will never be higher than about 60 degrees above the horizon. Why that value? Probably because of where Solarcan are based: in Scotland.

On third thoughts, there could well be justifiable circumstances for #13.
Guess I'll have to hang up my shirt made of wasps. NO DON'T OPEN THAT CUPBOARD!
ReplyDeleteI will add that I already look sideways at people who craft bee-beards.
ReplyDeleteSo I am sorry, but you should hang that up too.
NO! Not in the same cupboard!!!
I'm sure putting it in with the superglue and twigs will be fiiiiiiiiiine.
ReplyDeleteUmmm... just as long as it is not in with the wasp shirt.
