Spiral galaxy NGC 6384 stands out because Ophiuchus doesn’t contain many bright galaxies.

Martin C. GermanoIn the May 2010 issue of Astronomy, I described 30 obscure deep-sky objects you can find in the summer. Although I mentioned some objects’ magnitudes and sizes, I thought some observers would appreciate a complete list of attributes. We didn’t have space in the magazine for such a list. I ordered this list according to the way the objects appeared in the story.
