The Box Nebula and other faint PN's in Sagittarius
The Box Nebula (NGC 6445) is a fabulous little..?.."Gem" I guess in Sagittarius and made even more interesting by the fact that the small globular cluster NGC 6440 is in close proximity and makes for a lovely pairing.
Like most planetary nebulae the Little Gem looks best in narrowband so in order to show both the globular (which is reddened strongly by intervening dust) and the star field, plus the the Little Gem, all at their best, I have used a blend of narrowband data and RGB.
As a bonus and to my surprise, I found two other very small and faint planetary nebulae in the field, I couldn't find their designations so if anyone can help out with this, that'd be great
Both nights used were clear but with a significant Moon and cut short by heavy fog...always something The RGB was captured after Moon set.
Where's that cluster in Sagittarius? (for reference, if I don't get side tracked on M8, again...)
Hmmm? lemmi see ...ummm, open planetarium star chart program, open search facility, type in "NGC 6440", click go..wait a fraction of a second..and bingo! there you have a star chart on your screen that shows you exactly where it is
If you don't have a planetarium star chart software.....umm? it's not that far from the Lagoon Nebula
Glad to hear that you are happy with your new Astronomis Michael, and why wouldn't you be happy? It is a very nice image and a pleasant break from "in your face" vivid and contrasty images of bright nebulae
Those faint planetary nebulae can be easily missed - I still could not locate the fainter of the two!

Ha! Went to see the pic directly. I don't read your posts

It's a common problem caused by the over-whelming magenta of most of his images. Temporary blindness
Forgive the indiscretion, but it all seems rather blue cast to me Mike. That was the impression I took away (despite the lovely resolution on the main target)
Nice one, Mike! I haven't seen that object before.
Cheers,
Rick.
Yeah, it's not imaged that much really but it's pretty I reckon

Thanks Slaw, although they are like magnets for good reason...can't just stick to the top 20 huh?

Ooooh look, I post a blue biased image and you make another magenta joke man, gotta work on your material Lewis
Oh and before you jump in, yes...I looked very hard but couldn't find a jet for you anywhere
Some great images and targets Mike, the planetary is beautifully resolved and colours are very nice. I really like the composition with the globular too, very striking!

Thanks for the well meaning feedback Rolf .... now, enough already...what are you going to post??? the suspense is killing me it must be over 200hrs by now

Ok I am now guessing the Hubble deep field...
Mike
LOL, it's not deliberate - I've just been too busy with other things lately to make any serious dent in the various piles of data that need processing...
But I can confirm that data gathering for Project X has officially ceased, and processing started
Nice combo Mike. I didn't know about the little gem, so that's another one to go on the list. Problem is that the list keeps getting longer. Really colourful greens and blues in that gem.

Hmm - not 100% convinced about the colour Mike. Seems a bit too blue to me but what would I know. Colour aside it's a great shot of two objects that should be imaged more often.
