I imagine IC 4604 is seriously dim, Roy!

 

Very fine sketch. 

 

Clear skies from Aubrey.

Yes, it's dim. You have to stare into that eyepiece for a while, and have no other distracting light around. The Oxygen-III filter helped as well, but the Ultra Block and H-Alpha filters didn't. (Go figure.)

Wow, I can't even imagine seeing that. I'm assuming you were in some pretty dark skies?

Dark and transparent, I'd say.  Impressive observation, Roy.  waytogo.gif   Rho Oph is a binocular triple and one of my favorites to look at with binoculars or a wide field scope because you can fit Antares, M4, and rho Oph all in the same field.  Of course, you can't see any nebulosity at those low powers--at least I haven't been able to.
