Hello Star Forming. I know I'm a bit late in responding to your question but we are a business on the island called Kosmos Lanzarote which is run by a qualified and highly experienced astrophysicist. We have dedicated our activities on the island to the residents for a number of years but this summer we have just started up our own ASTROTours and activities for visitors to the island. You can find out more on our webpage
http://www.kosmos-lanzarote.com
and on Facebook: Kosmos Lanzarote in English.
We run a planetarium, organise guided astronomical walks with binoculars and observation nights with telescopes, courses on astrophotography...
Please feel free to email me, Amanda if you intend visiting Lanzarote again or if you have any questions or need recommendations.
