Capturing dust in C.Australis and a Black Snake!
Here's an image from last new moon under mersing sky conditions. A change from the usual emissive nebulae, Corona Australis is a haven for capturing interstellar brown dust structures, but have always been "eclipsed" from the Sagittarius and Scorpius notable DSO jewels. Nevertheless, it can be a busy and interesting region. In this FOV, there are several objects in view. Took a while process. The little brownish curly nebula at center is NGC6729, and the light bluish reflective nebulae - NGC6726/6727 and IC4812, not forgetting the top-right globular cluster NGC6723. The dark nebulae stretching from lower-left to center and enveloping the greater spatial region is B157. Taken with the Takahashi E210 astrograph on an almost limiting G11. 45min total RGB. Hope u have fun looking around this area next time!

Another shifu grade photo. Thanks for sharing
Re: Capturing dust in C.Australis!
Nice! Is the star behind the blue reflection nebula a double star? From the diffraction spikes, it looks like one. 

Re: Capturing dust in C.Australis!
Thanks Clifford!
Kel: Oh yes. It is designated BRS014 double. Actually that was the double that gave a false impression that the system was not in focused. Wasted half hour trying to attempt refocusing only to know that it actually was ok!

Awestruck...
. Just included it into my A-list of imaging targets

Re: Capturing dust in C.Australis!
Awesome photo because it there is so much "activity" in there! Many key DSO components are represented, dust, stars, globulars, binaries, etc....

Hello Remus,
I am delighted to see this image. NGC6729 is a well-known variable nebula, which is illuminated by the variable star R CrA. I have recently been researching Harold Knox-Shaw (1885-1970), a British astronomer who first characterised the variability of the nebula in about 1915 using the 30-inch Reynolds telescope at the Helwan Observatory near Cairo Egypt.
Go well!
Jeremy

Amazing what f/3 and 210mm can do in 45 mins.
Superb image. Congratulations.
Cheers
