Last new moon my friend Anthony and I had a great night of observing and imaging, had great seeing and transparency on the same night. It had been a while since I did a star trail image and I had just gotten this lens so I thought I would try it out. I used MaximDL to calibrate the images. 71x180 seconds Canon 5D Mark I @ ISO400 Canon 24mm F1.4 L II Lens @ F1.4 Here is a link to a single daytime image if you are interested. https://c2.staticflickr.com/8/7549/26747446052_90f60e69fd_o.jpg
