Well thank you one and all I appreciate the feedback and nice comments

Regarding the colloquial name of NGC 6445, it seems there is some confusion out there, not only is it referred to as The Little Gem in my Planetarium software Star AtlasPRO, I had also found several other references to NGC 6445 as being The Little Gem and here are two:

http://server7.wikisky.org/starview?...6445&locale=EN

and

http://rao.150m.com/NGC6445.html

However... digging a bit deeper

THIS may be the reason for the confusion (first paragraph), seems there was an error some time ago in the Sky Atlas 2000 Vol 2..?

The Little Gem seems in fact more likely to be NGC 6818 (also in Sagittarius). Seems NGC 6445 is more often referred to as The Box Nebula in most cases.

Have to admit though, it is a little gem of an object though

Anyway...great news!

I had conformation of the nature of the other two faint PN's I found in my image...one of which I was only 13yrs too late to claim the discovery

This from sky object guru Sakib Rasool:

"The one on the top is called PN G007.9+03.8 and was only discovered in 2002. It is one of nearly 1200 MASH planetary nebulae, see the Ha image here: http://cdsarc.u-strasbg.fr/viz-bin/v...&G007.9%2B03.8

The second is also from the MASH survey, this is PN G007.7+03.9, see here: http://cdsarc.u-strasbg.fr/viz-bin/v...&G007.7%2B03.9

Also I think the halo around NGC 6445 might have been discovered in 1986 or 1987.
"

Thanks again guys and nice to know at least some people read image posts more carefully than Marc ...will make the necessary name changes.

Mike
