WOW! Great images! They are all merit an APOD!
I like the movie and the odd clouds in the last image best!
Best wishes,

All images are amazing, but the timelapse is breathtaking, maybe because we're not used to see these things move like that :)

Hi:
The photo of the radiotelescope is excellent, although for my taste the green tone in the terrestrial landscape, leaves exceeding.

Hello,

Just a few comments about the "Making of" the Cotopaxi Time Lapse Movie.

This movie was taken 2 weeks ago in Ecuador.
I spent the day and part of the night at altitude between 3800m (12700 ft) and 4500m (15000 ft) finding the right spots for my three cameras. The weather was partially cloudy that day so I wanted to install all my equipment but at separated locations. One of the camera did not see any stars at all the whole night, the one at 3800 so partially the sky (first part of the movie) while the third camera, placed higher up the volcano was more lucky (end part of the movie).

It is literally "breathtaking" to walk and climb in these beautiful landscapes at such altitude with 21 kg of equipment (cameras, tripods, batteries). Because of this altitude, you MUST have a written check list in order NOT to forget anything, even obvious (because your brain might work slower due to the lack of oxygen) : adjust correctly all the camera parameters, put a memory card in the camera, focus the camera, switch ON the camera also, eventually remove the lens cap .... well in my case I forgot only one thing : to take that checklist along with me :) !

Thanks mexhuunter,

The green in the radio telescope comes from a light at a neighboring ranch -- it really is that green in a long exposure. In fact, this image is one example of light pollution (and clouds) really adding interest. The green light provides key illumination, while the orange light from a nearby town illuminates the clouds : )
