Corona Australis nebula

[ozstronomer]

Out at a dark site and tried imaging Corona Australis for the first time.

I know there is a lot of dust associated with this nebular, but I found it difficult to process, any help/comments appreciated.

Scope: w.o. flt110 Camera: Canon 20d (Modded) Approx 3 hours with darks and flats processed in Photoshop CS3

Thanks Geoff

That's just awesome guys.

Nice image. Lots of great detail and well processed.

Can I just say though. Your spelling of the word Nebula is incorrect. It does not contain an R at the end of the word.:)

[TrevorW]

Sorry Paul but can include the letter R when written as an adjective


neb·u·la

alt="nebular pronunciation" las. 1. Astronomy . a. Also called diffuse nebula. a cloud of interstellar gas and dust. Compare dark nebula (http://dictionary.reference.com/browse/dark+nebula), emission nebula (http://dictionary.reference.com/browse/emission+nebula), reflection nebula (http://dictionary.reference.com/browse/reflection+nebula).

b. (formerly) any celestial object that appears nebulous, hazy, or fuzzy, and extended in a telescope view.

2. Pathology . a. a faint opacity in the cornea.

b. cloudiness in the urine.

Trevor, the use of an adjective is still incorrect anyway. Why is this being excused? It is not the correct spelling for the grammar.

[TrevorW]

Paul, it's irrelevant we are viewing the persons image not c & c'ing his grammar, although the word nebular can be used should I correct both of you and say he should use the term nebulae as there are more than one nebula

IMHO some people of late have been to pedantic about grammar and offer very little in the way of constructive criticism. Remember also that these threads are often written on the spur of the moment, withouta thought of spelling or grammar.

By the way a very nice image, the dust lanes and nebulae are showing up well.

For all.

There are no Messier objects in Corona Australis, however the constellation does have a globular cluster suitable for binoculars, as well as an interesting region of nebulosity that goes under a multiple name.

NGC 6541 is a globular cluster, quite large and bright, about 15,000 light years away. It's nearly midway between theta CrA and theta Sco, a bit closer to the latter (more precisely thirty arc minutes east of theta Sco).
NGC 6729 is part of a nebulous region that contains both variable stars R CrA and TY CrA.

The region is a mixture of bright and dark nebulae; the brightest region is NGC 6726/6727, which form a figure eight. Just to the SE is NGC 6729, which is much fainter, but of more interest as it contains R CrA, an irregular variable that goes from 9.7 to about 12. As the star brightens, so does the surrounding nebula. The other variable, TY CrA, is found in NGC 6726, and varies from about 8.8 to 12.6.

The easiest way of finding the nebulosity is to drop seven and a half degrees south of zeta Sagittarii.

Yeh Geoff that nebyooler image is quite nice, good to see the left extension of dust too, maybe you coudld image the right side half and mozaic them together?

Oooh!... spelling bee :fight: Nice shot Geoff. Very sharp. :thumbsup:

[ozstronomer]

Thanks everyone for the feedback on the image.

Funny you might mention the spelling Paul, because as soon as I had posted the image I realized the mistake and tried to edit it. However, it seems I could only edit the body of the post not the title.

Is there a way around that? edit: (Found it in the Go Advanced section)

Thanks Again

Mmmmmmm nice nebulae, you really have to go 10 hrs plus if you want to brighten up the dust without introducing too much noise.

[mithrandir]

Grammar is irrelevant to the quality of Geoff's image, but we pedants love to pick on people's misuse of it as something to amuse us a cold wet night.

Trevor, you need to review singular and plural nouns.

he should use the term nebulae as there is more than one nebula

[TrevorW]

Andrew did you run that through Microsoft word and get "is" using the grammar checking

"are" is correct in this text as we refer to the word nebulae which is plural the second part of the sentence is singular

if we had written

the nebulae is comprised of a number of nebula, then this would be more grammatically correct

[mithrandir]

It is the phrase "more that one" that makes it singular. And no I don't use any Microsloth product if I can avoid it. Try "The little Green Grammar Book". If you hunt through the archives I have quoted the ISBN at some time.

[TrevorW]

Thanks Andrew, I will see if I can find a copy, this particular issue can be confusing even to the best of us !!

[Geoff45]

Nice and crisp, but needs to be offset to capture the glob that is out of frame to the right. IMO including the glob really makes the picture..
Geoff
Did a quick re-edit to capitalise "nice" to avoid the grammar nazis.

[Hagar]

Come on Kids behave. Nice image of the cloudy and dusty thing.
You may wish to adjust your framing a little to capture more of the main dust lane as you will find it looks more complete with the right hand side extended a bit.

[gregbradley]

They is nice nebulae. Well done

Greg.

Sory I mist this won first thyme around, Geoff. Wonder full shot.
