Hardly visible at 98X without filter, NGC 6804 was pretty easy with the filter
in place, dispite being 12 mag. at quite large. Roundish nebula with just a 
slight elongation. The nebula is not uniformly illuminated and there was a hint
at a dark central hole, like M57. This could be illusory though.
Less than 1 degree from NGC 6803 with which it shows a wonderful contrast in
types of planetaries.
