View Full Version here: : Corona Australis Wide Angle

Hey all - this is a wide-angle view of the Corona Australis molecular cloud.
The FOV is some 12 odd degrees on the long axis but I still didn't manage to fit it all in - what a monster of an object!
This is 45 x 90 second subs through the Samyang 135mm telephoto at f3.2.
Tracked (but unguided) on the "lightweight setup" (my 33 year old Vixen SP mount) which is still going strong despite being dragged to the USA two years ago for the eclipse. :lol:
Higher res view here at: Astrobin (http://www.astrobin.com/full/407994/C/?real=&mod=)
Didn't get as much data on this as as I was hoping (originally planned to capture this at SPSP but the weather didn't play nice) so hope you like it anyway. :)
Pete.

Nicely done. So we learn from your image that Master Yoda and his Herbig-Haro jets are in the mouth of a great big wolf.

A very pleasing widefield. What camera was that?
I have a similar image I took a few months ago yet to be processed.
Widefields are fun and give a refreshingly different view to these objects.

That's a great composition Pete. Many ideas to explore here and many more imaging projects that I must now follow up. Good one :thumbsup:

Nice one Pete. Corona Australis dust tail keeps going for ever. Nice widefield of it. :thumbsup:

Thanks MnT. I see a shark myself - I expect it's just some sort of cosmic Rorschach test! :lol:
Thanks Greg!
I used a modified Pentax K-5iis DSLR (APSC). It is a newer variant of the K-5 without an anti-aliasing filter. The K-5 is getting rather long in the tooth these days (I bought my K-5 back in 2012) but its sensor still holds up quite well as long as you don't try and go over 3200 ISO.
Looking forward to seeing your version. :thumbsup:
Thanks Rodney - much appreciated!
Thanks Marc - yep that tail just keeps going. I didn't think I'd need to do a mosaic at a mere 135mm fl but there you go.

The thing many don't realise is just how expansive this dusty nebula is :eyepop: Nice job with limited data there Pete :thumbsup:

Hi Pete,
That's a great perspective!
I hadn't seen the full extent of the dust before.
Cheers,
Tim

Thanks Mike - yep would've liked to go deeper but conditions and issues conspired against me. Saved a little by imaging at f3.2. :thumbsup:
Hi Tim - thanks for the comment.
Still a bit you haven't seen yet I think - perhaps a full-frame sensor would've captured it all. ;)
Cheers,
Pete

Wow! I had no idea it was soooooo big - that's very nicely done, a new perspective on a familiar target! :thumbsup:

Co-incidentally this version (https://www.astrobin.com/full/409381/) popped up on Astrobin today - the thing is HUGE! :eyepop:

Lovely image that encompasses the entire region. Colour and presentation of the fainter nebula is excellent. :thumbsup:

Thanks Andy!
Wow that is deep - rather reminiscent of Mike's amazing FSQ version.
Thank-you Paul!
