Another great thing .
I've seen pictures of people doing out reach on the street. They have a mini projector pointing to the ground - either on a road or a white sheet. So the live image is about 1or2 sq metres.
It's looks awesome. Saw one of M42. Another of the moon where kids could literally walk on the moon !!
That's outreach
