At astroGC we use free software for post processing of images. The camera is setup to save a RAW format of each picture. This produces extremely large files as it just save all the infomation from the camera chip. But this format alows to retouch the color balance, exposure and hundreed of more parameters. We do this treatment with RAWTHERAPEE, a free program under GNU licence. Afterwards, a last retouch can be performed with GIMP, also free / GNU licenced program. Thanks to both companies for developing such powerful softwares.

Since mid March, the Canary Islands have been under a very strict lockdown imposed by the Spanish government. The virus was spreading at very high speed in Madrid, Basque country and Catalonia. The central government implemented in whole Spain (including the Canary Islands) one of the strongest lockdown in the world, similar to the one implemented in Wuhan.
In the last few weeks most of Spain is recovering very slowly a kind of "new normality".
astroGC, as a company up in the Outdoor Activity oficial database is allowed to run excursions in the mountains at any time of the day or night from "phase I" lockdown.

But there are no tourists in Gran Canaria right now. Absolute zero. There are some travellers who decided to stay here. They had to leave their hotels to rent an apartment with kitchen to be able to cook. They are somehow some new residents.
This is the case of David and John (fictitious names). D…

Happy to share with you this nice shoots we took during this week:



This one has been taken using a mobile phone and our powerful hand made telescope. The waning moon is rising up the pine trees situated about 15 km away. A few clouds on the horizon give a special interest to this picture.


This one is of our hand made telescope. In the background there are a few pine trees I was lighting with my front headlight during the 30 seconds exposure of the photography. This is a genuine picture. Nevertheless the post treatment of the foreground is slightly different from the post treatment of the background with the starry sky.



This one has been done yesterday. Despite of an apparently clear sky on the picture we actually had troubles with clouds yesterday. We finally had to go up to Roque Nublo (Center of Gran Canaria). The sky was clear there and we enjoyed a very good astronomy observation.

Hydraulic power station in Gran Canaria

Image
The company Red Electrica de España is planning to build a huge hydraulic power station between the dams of Soria and Chira in Gran Canaria.
This is quite near the area where we are going to stargaze at astroGC.
Fortunately the area being protected, the hydraulic power station will be underground.




The plan is to pump the water up when the wind turbines are producing more energy than the consumed energy on the island. And recover this energy when needed.
More info (in Spanish) here: www.soriachira.com
