Analemma at 7:00:00 in 2013.

My analemma project started on December solstice in 2012 and finished on December solstice in 2013.
This photo contains the sun images from Jan. 18 to Dec. 22, that is, all the sun images are only in 2013.
Analemma photography requires an astronomical precision alignment, so I used a triple alignment; fixing the mount to the mark on window bar, a rough alignment of the field of view using 2 corner points in the camera view, and a precise alignment of the images using ridge lines of 2 buildings with rotation by 0.01 degrees and magnification by 0.1% on Photoshop. (Each sun imae with ND was taken sequentially with the scene without ND and overlaid for the third alignment)

Nikon COOLPIX P510 digital camera;
ISO 100, F3.0, 1/4s to 1/30s exposure, f=24mm, ND 100000 for the sun, taken at 7:00 am using a radio-clock.
ISO 100, F3.0, 1/2000s exposure, f=24mm for the scene to building alignment (not used in the final image).
ISO 100, F8.3, 1/400s exposure, f=24mm for the background of analemma, taken on Jan. 19, 2013.

Thank you very much, gadieid.
1 year was very long for me to achieve this project.

The alignment method mentioned above is, I think, complicated but safer against image misalignment. And besides, no need to keep a camera on a fixed mount for a year. I wanted to take other photos using my camera, of course, so I fixed only a clamping mount onto a marked window bar and adopted the triple alignment of images using building edges. It is important to take 2 sequential photos of the sun with ND and the scene without ND, carefully, without any displacement of camera or mount.
Thus, I could achieve a precise image alignment, even if every time I removed my camera from the mount.

A few of us, analemma photographers (I made one for Kolozsvár city) know how long a year can be. Great job :)

Thank you very much, dear vnp,
I saw your website with the analemma of Kolozsvár. That is a very excellent article.
I am glad to receive a message from analemma photographer.
