I’m tired today. With good reason. I was awake for 22 hours yesterday, I got to bed gone 5am this morning and I’ve had 2.5 hours sleep. But it wasn’t all in vain. I decided my target for this month was to photography Pen y Fan at night to show the rotation of the earth in the form of star trails. So, I drove out to the Neuadd Reservoirs and got there at 9:30pm. I walked half a mile up onto the hill, found a suitable spot and settled down. I balanced my 5D Mark II on a bean bag and rock whilst the 5D got the tripod. I waited until 11:30pm when it was dark enough and set about taking a series of 30 minute exposures. The 5D battery lasted for under 1.5 hours of exposure whereas the 5D Mark II battery lasted for over 4 hours! I left the hill at 4am after taking lots of photos, drinking lots of coffe and getting cold knees. I even dozed off to sleep for a few minutes, but fortunately woke up before the 30 minutes of an exposure was over. I stacked the images in Photoshop this morning. This is the result:

Pen y Fan Star Trails (Canon 5D Mark II) 3 hour exposure

Pen y Fan Star Trails (Canon 5D) 1.5 hour exposure
