Many highlight the passionate volunteers and the beautiful grounds as major draws. While some note that younger staff may lack in-depth knowledge, the overall experience is described as extraordinary and highly recommended, especially for families and astronomy enthusiasts.

"An important piece of history. We found this by chance while looking at the Atlas Obsura app and we were only 20 mints or so away, so we went to check out out.
Very cool. Very impressive what has been discovered with this very telescope during its career.
Even more impressive it still functions. We're hoping to be able to look through it one day."

Mike T

"Great experience going through this wonderful historical site, we went during the 90th anniversary so everything was free. Went during the day so we didn't look through the scope but it was still fun! Recommend going during night so you can see through the scope itself. Still a nice experience and recommend going before it becomes paid again"

"We had a program with 1st Maple Scouts yesterday! Lots of fun!! Even got to observe Saturn before the clouds came in!"
