I got it Compiled!!! We went to Glen Canyon Dam Overlook in Page Arizona around midnight.With camera on tripod and remote in hand took a 20 second shot repeatedly for 2 hrs. Maybe I didn`t need that many but it was my first try at star trails. Now that I am home and able to work on computer I have removed the airplanes in each shot and blended them together to get this result.
Lovely. The North Star is right over my chimney(!) so I've played star trails - the easy way. My Oly EM10 does it all for me with clever live composite stacking in camera. I applaud your patience.
