Star trails around Polaris (Alpha Ursae Minoris) – A picture that says the Earth still rotates on an imaginary axis that points nearly towards Polaris - This final picture is the result of 126 clicks @ 24mm-f4.0, ISO2500, Exp:10 to 11 sec in manual mode, focus on near infinity on a full frame each stacked together that spanned 30 minutes of star trails. The intervalometer was simulated using the Eos Remote Android app by clicking the shutter release button on the app screen and holding it till the screen counts 10 or 11 secs and then repeating the whole thing for the next 30 minutes. These clicks are captured from a spot near the road R251 that leads to Mt. Errigal from Gleanveagh National Park.
A time lapse video with these 126 clicks is uploaded onto YouTube - https://youtu.be/Le5U4xgacPA
The temperature was around 10 degree Celsius outside the car at that time (12:15 am to 12:45 am) , so I kept the camera as close as possible to my car's radiator to prevent lens fogging, and now I feel that I should have a 12V hair dryer handy for any future attempts.
