Hi, i reguarly go to Chichester Planetarium to watch the night sky shows and they are really spectacular! Iam also a member of the Star Club, this is where we have special shows just for our group and its really fun.
Even though iam not a 100% devoted astronomer, i find the expetience so friendly as the enthusiasts are very friendly and are able to tell us fun facts without using technical jargon which is nice.
Here is a link to Chichester Planetarium (hope iam allowed to post links)
