What are some really fascinating deep sky objects in the constellation Ophiuchus?

There's a bunch -

http://www.hawastsoc.org/deepsky/oph/ind…What are some really fascinating deep sky objects in the constellation Ophiuchus?The Rho Ophiuchi cloud complex, a dark nebula of gas and dust that is located 1° south of the star ρ Ophiuchi of the constellation Ophiuchus. At an estimated distance of 131 ± 3 parsecs, this cloud is one of the closest star-forming regions to the Solar System. http://apod.nasa.gov/apod/ap100524.html



Ophiuchus also contains several star clusters, such as IC 4665, NGC 6633, M9, M10, M12, M14, M19, M62, and M107, as well as the nebula IC 4603-4604. The unusual galaxy merger remnant NGC 6240 is also in Ophiuchus.What are some really fascinating deep sky objects in the constellation Ophiuchus?
1. There are seven globular clusters,M :

10 (visual magnitude 6.7), 12 (magn. 6.7), 62 (magn. 6.6), 107 (magn. 6.6), 9 (magn. 7.3), 14 magn. 7.7), 19(magn. 6.6).

All of them need a Binoculars to see.

2. Barnard's star (magn. 11.3), the star with the greatest proper motion (10".29 PA changing by 1 degree in 351 years).

3. (Dark) Pipe nebula (B78 in the bowl, B59, B65, B66, B67 in the stem), 'S' nebula (B72) and theclouds of Milkyway are some more.What are some really fascinating deep sky objects in the constellation Ophiuchus?There are a lot of globular clusters, open clusters, and dark nebulae. My favourite object in Ophiuchus is Barnard's Star, but it is not a deep sky object. In fact it is one of the nearest stars to Earth and has the greatest proper motion of any star in the sky.What are some really fascinating deep sky objects in the constellation Ophiuchus?
Ah, I remember putting the glass on Hale-Bopp passing through Ophiuchus on its inbound leg, back when it was just a little squirt. No more, though....What are some really fascinating deep sky objects in the constellation Ophiuchus?M10, M12 both Globular clusters,
