Rising moon X20

Image
This is a time lapse of the moon rising up the mountains in Gran Canaria island yesterday.

It has been done with our handmade 16'' telescope equipped with a 38 mm x 70º eyepiece and the Samsung mobile phone of one of the guests.

With this eyepiece, the telescope was magnifying the moon 47 times.

The speed of the moon rising up has been multiplied by a factor of 20.

Enjoy and share with no fear.

Thanks.





Astronomy workshop for everyone

Image
We were happy to welcome Phil and Sue to the astroGC astronomy workshop the day before yesterday.
With their agreement I publish the photo we took of them at the end of the workshop.
We only had to face some problems due to the moon light disturbing the deep sky observation.
The rest was just fine.



Celestial rotation viewed from Gran Canaria

This is a time lapse video of stars apparently rotating around Polaris star.
Polaris, also called the North star, is quite low in the sky due to the video has been done from Gran Canaria at 28 degrees lattitude. This time lapse has been done by Andrew Lockyer during his holidays in Gran Canarias. Andew is deeply concerned about the understanding of the place where mankind is living. He came to the astroGC astronomy workshop during his holidays and also took this video from his resort in South Gran Canaria. Thank you for sharing Andrew, and thank you for participating actively in our astronomy workshop. Gauthier.

A closer shot of the moon

Lastly we had winds from the East in the Canary islands. The East winds bring dust from Sahara desert. This is named "Calima" is Spanish.
For some reasons (we do not know) the atmosphere is particularly quiet when loaded with Sahara dust. There are very few turbulences and we still have sharp images despite of magnifying 225 times.
One this picture, we used our handmade 16'' telescope (1.80m focal length) along with Ethos 8 mm X 100º eyepiece and a decent mobile phone.
Enjoy and share with no fear.
