NGC-6210 is very bright but tiny. At anything much less than 100X, you can mistake it for a star. It does respond well to nebula filters and even better to magnifications in the range of 200 to 250X. It is not the easiest object to find by star hopping, but a slow careful search of the area will show a bluish object that looks like a star that won't focus. That's NGC-6210, and if the seeing is steady, try looking at it at 250X and see if you can see the central star. I've seen it but when the seeing is poor the surrounding nebula hides it from view. It's also known as the Turtle Nebula because of some peculiar projections from the inner shell that resembles the outline of many a terrestrial turtle's head, shell and limbs.
