Photo Adventures with Curiosity and Learning

November 02, 2016: International Space Station

A friend suggested I look for ISS passes. I got an ISS transit forcast for my region, GoISSWatch - and this morning was a pass near 90 degrees (straight up). I set my camera to take sequential 15 sec exposure and started the sequence at 06:14 - just before the predicted pass. I did not see the pass, but my camera caught it - as shown below

I first tested my exposure with bright constellations - here is Orion in the western sky

and the Big dipper in the Northeast sky

Here is a composite of the four 15 sec exposures that captured the transit

After the ISS pass - I explored the region with my UV flashlight. Here I found tree frogs eyes fluoresce

Here, the iris was not totally open - and it appears that something inside the eye - perhaps the retina

Non fluorescence of frog iris - but fluorescence of the frog lens or retina
