The Corona Australis Molecular Cloud

It is the bright busy pointy end (top right half in this shot) of this large faint molecular cloud that is usually imaged at tighter image scales as it contains some cool features including R Corona Australis inside its variable nebula

The Corona Australis Molecular Cloud as a whole though is a much larger, faint gaseous and dusty molecular cloud with many embedded reflection nebulae as mentioned, including NGC 6729, NGC 6726–7 and IC 4812. A star-forming region of around 7000 Solar masses, the cloud contains Herbig–Haro objects (protostars) and some very young stars. About 430 light years away, it is one of the closest star-forming regions to the Solar System.

With a 4deg wide field I was able to cover most of the extent of the molecular cloud but a second panel would frame the lot.....

Ever wanted to know the designations of the various bits?..Here is an annotated version

I think you need to clean your FSQ Mike, there seems to be stuff smeared all over the field blocking out the stars

That's a beauty, Mike! I'm thinking about chasing this object at Astrofest with a DSLR.

Cheers,
Rick.

The way you've presented the dust, sometimes obscuring the distant stars, sometimes being lit by the nearest stars, sometimes a bit of each, is wonderful. Then, if one zooms, in, so much detail.

Toward 7 o'clock from the globular is the large and detailed face of a camel or perhaps a yak, with Yoda's Walking Stick on the bridge of the nose between the eyes. It is all there, including a very clear nostril, mouth, and cleft upper lip. I had no idea it was there!

Lovely image.
Mike

Ah, so that how the (nearly) entire region looks like! Awesome image Mike, as always

I really enjoyed browsing the large resolution image. Perhaps a silly question - but any idea what those streamers coming out of the bright blue star (at about 2 o'clock from IC4812) are?

Very cool Big Mike. Nice processing. You didnt blow away the bright glob.

That's a dusty bugger and look at all those stars. Good star shapes right into the corners.

A fabulous vista Mike. A grandious voyage across a dusty plain with some stunning blue highlights.

The star field is also very vibrant.

Greg.

That's truly incredible Mike... I never thought I would see the day.

Not a single emoticon in your post.


Oh, and yes
that's a pretty good image as well.

That's kinda NOICE!

Going to have to revisit it again with the FSQ-106 instead of the FSQ-85 like before. Interesting I got the red in the hockey stick swirl whereas yours doesn't show it.

Thank you for presenting the 'big picture' here Mike. As you say, we are normally focusing on the pointy bit at the end so it is good to see a fine display of the surrounding area.

Seemingly every bit of dust there is clearly shown, so deep indeed, yet nothing is blown out, and the FSQ is so optically perfect, stars right in the corners exactly the same as in the middle not a hint of abberation. A truly stunning picture.

Top shelf image again Mike - that shelf must be about to topple over with all the goodies on it now!
Lovely wide vista, pts the objects nicely into context - well done!

Thanks a lot Slaw As to the source of the weird star spikes on that star...no idea first time I have seen this strange almost skewed pattern.. I have noticed complex diffraction spikes, of varying appearances, around bright stars with both my FLI cameras and with both my refractors (FSQ and AP152EDF) but not my Newt....strange how it is only that one star in the field too...

Thanks a lot Dave, wide dusty fields are good to shoot with this combo

Thanks a lot Scott and yes the FSQ106EDX4 is a remarkable scope for sure...makes my job pretty easy really

Yes, one star only in the entire image so it did trigger my curiosity. And the spikes are actually very unusual and kind of pretty, so I was allowing a possibility of a nebulosity interfering with the light coming out of this star.

Or perhaps it is the lens-camera combination at some specific angles creating such unique localised patterns.

Yes it is strange... this shot shows the effect I had noticed on some bright stars (but not all) before but not in all images and only on some bright stars..? It doesn't worry me at all but it is intriguing
