Actually, I shot the footage of this timelapse more than 3 years ago. Though I kindof “lost” the images on my backup storage and forgot about it. A couple of days ago, I stumbled upon the files…
I sent a few days at a farm in northern Sardegna, Italy during a late August full moon. The terrace of the main building offered this splendid veiw of the countryside and pigs enclosure (you may see a few pigs running around at the end of the video). The full moon cast a shadow all night long, while the stars pass around Polaris.
The timelapse was shot between 19:44 and 08:53, covering 13 hours with 777 single exposures.
Post processing in Lightroom and LRTimelapse
The following timelapses show, how much angular distance the comet 46/P Wirtanen makes, when closest to earth. From my data I see approximately a stunning 1° during 4 hours!
85mm photo lens with 1.5x crop sensor
93 exposures, each 60 seconds long (93 min total)
200mm photo lens with full frame sensor
160 exposures, each 90 seconds long (240 min total)
715mm/f7 APO with 1.5x crop sensor
71 exposures, 30 and 60 seconds over 80 min
I went to the observatory (see previous post) to capturing some deep sky photos. When the camera was capturing in the meantime I set up my slider. The slider was configured to travel an inclined track with 6m length. The plan was to show the milky way above the observatory, travelling away from the dome.
This is the 3 hour hyperlapse:
At night, with long(er) exposures, the slider concept to stop for each frame, proofs to be perfect!
A test at night with 10 second single exposures:
Crisp and clear images due to stop-motion. But not yet fluid motion (there seems to be a bug in the motor control).
To be continued 🙂
After several days of building and coding, the slider was ready to perform a first real world test. Even if the electronics have not yet been encased (all the wires are going wild around the platform), this was proof of concept…
After working through all the data collected from the solar eclipse in August, I combined the wide angle images (8mm lens) and the images captured through my 600mm travel telescope to timelapses. The wide-angle video is the result of more than 800 single exposures, covering the day from around 6am till 5pm. The most interresting part around totality is significantly slowed down, as totality would be over in a blink. During partial phase, I was so busy trying to fix my automated triggering system, that I did not realize the clouds until post processing. So it was really pleasing to see all the clouds above my site vanish moments before totality began. On the other hand, the remaining clouds increased the view of the shadow of the moon passing over, which is just amazing!
The inlay in the wide angle video is derived from the high res video.
I am really pleased with the results, but check for yourself!
I condensed in this video the first 18 days on the road to a 5 minute movie. A lot of countryside besides the roads may be seen, but the video gives just a hint of all the beauty lying beyond, when you get out of the car an make a few paces. So, get out of the car and enjoy the places you would otherwise rush by 😉
The following map (generated in google maps with a few marker points along the route; the full path would exceed the maximum allowed waypoints) shows the coarse path we went:
About the video:
– 4K action cam attached to the upper right corner of the windscreen with a suction cup mount
– camera captured a still image every 3 seconds
– covering 19 days (18 on the road)
– almost 80 hours driving
– more than 3500 miles covered in the video
– 94500 images in 257GB data
In the night of 2017-08-14 I created a timelapse with the milky way travelling above Monument Valley. Clouds and the crescent moon did interfere the beautiful sight of the millions of stars above one of the most impressive sights in the US. On the other hand, an amazing sunrise compensated for the second half of the night 🙂
