Moonrise behind the Sacré Cœur basilica in Paris

IG :

Hello here is a timelapse I made of the full moon rising behind the Sacré Cœur basilica in Paris.

The Moon looks particularly big because the picture was taken at 11km distance with a 600mm lens. You can see the turbulence of the air due to this distance. I had to stabilize the timelapse because the turbulences were so important that the image was shifted by 30% in all directions...

I used the same settings from the beginning to the end because I was too afraid to touch the camera and completely off center the sacred heart. The pictures were taken on November 9th.

Settings : ISO-800 - F/6.3 - 1/30 sec
Equipment : Canon 750D - Tamron 150-600mm

Timelape: The Exploding Crab Nebula
Timelapse video URL:

It is rare and exciting to see any changes in astronomical objects outside of our solar system. However, incredibly, this time lapse animation is two images taken exactly 13 years apart. Clearly visible is the expansion of the red glowing filaments of ionized helium and hydrogen, as well as the swirling blue-white cloudy material illuminated by synchrotron radiation. Also note the proper motion movement of the yellow-orange star in the lower left corner of the image. Many more details including animations and annotations available here.
