Brian, and planetarium staff, I just stumbled upon your channel and content. I really appreciate your explanation, graphics, annotation and background music. Very well done Such work deserves high praise and certainly more attention by the RU-vid community. I will make reference to your work with others I know who love to gaze at the stars as well as in future Astronomy outreach events, that I hope to once again participate in (later this year with my club, ASEM, in the St. Louis area). Thank you for making such content public. - Tom
