A confirmation e-mail will be distributed to the sender as soon as humanly possible to describe the dates planned for the future. There are no obligations to these dates! Lastly, dates may change as the weather (As antagonistic as it can be) can alter affecting the possibility of the desired night. Hence why contact details are necessary for such rapid changes.
Thank you all dearly,
PS. Don't hesitate to bring along your own telescope! We love seeing new people interested in Astronomy and all of its wonders, so make us two happy men and come for the experience...
