Some high cloud, but we had a close pass of the ISS to the moon this evening.

Using a Solarcan Puck at lower lattitudes
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. What do the the rest of the world have to do then? You can restrict yourself to winter months - but that is not much fun. The other alternative is to angle your Puck upwards. But how far? In the worst case, on the Equator, the sun will be directly overhead at Solstice. This means that the Puck will have to be angled upwards at least 30 degrees - but this would mean tha
Tell the moon to stop hogging the Pong.
ReplyDeleteAlicia Smith I can see we're this going lol
ReplyDeleteI didn't take pic of pass but moon was nice tonight through scope https://lh3.googleusercontent.com/XEgD_kyM7vgzznzCuC2HpIE3JssZK4l5ICC-uRx5yieXBhIC3KWB1Pt_oWsfnqaGJikZu7tYcK2oAqSUI6rAMv9GiLAlzxZpJmc=s0
ReplyDeleteThat gif looks a bit like ISS slowing down to yield to Moon, then speeding through the intersection.
ReplyDeleteNice shot Elaine Walker!
