One of the main viewing objects of the August 24th session was the Ring Nebula. It’s an object that can’t be resolved with binoculars and is almost directly overhead in our Northern summer skies.
Nebulae and other deep sky objects benefit from having a larger telescope to collect faint light, having a calm atmosphere (Saturday was “average”), and having little to no light pollution. The best case, as in the Hubble telescope pictures, is to be above the Earth’s atmosphere completely, but that’s not something easily arranged. The pictures in the Wikipedia article linked above are very nice examples, some digitally enhanced. We pushed the edge of a couple of those categories, but most people were able to see the “ring” aspect of the nebulae (this link leads to a picture closer to what we saw).
