I have always really loved this small but beautiful nebula in Carina, ever since seeing David Malins version all those years ago...but strangely this is the first time I have imaged it :)

IC2220 is a cloud of gas and dust illuminated from within by a star called HD 65750, a red giant star about 5 times more massive than our Sun, you can read all about her HERE (http://www.eso.org/public/news/eso1343/)
The nebula sits in a complex region of very faint molecular dust too.

The seeing wasn't particularly kind to me on either night but I think all in all it came together reasonably ok in the end.

Full Frame (http://www.pbase.com/strongmanmike2002/image/162508998/original)

Huge faint outer halo and Milky Way dust (http://www.pbase.com/strongmanmike2002/image/162542492/original) (high contrast stretch)

All imaging/capture details are under each image.

The Toby Jug shape was first coined by David Malin, Paul Murdin and David Allen when they noticed the strong resemblance to the once popular china jugs (http://www.worldcollectorsnet.com/features/tobyjugs/)
...I see the Toby Jug but in the full frame orientation it reminds me of a Golden Orb Weaving Spider (http://www.pbase.com/strongmanmike2002/image/162530689/original).

Cheers

A fantastic jewel that I have never seen imaged before!

Very well done Mike!!

Nice one Mike. Often thought of doing this one myself but I've never got round to it.

Cheers

Excellent image, Mike. I love the way it glows.

Cheers,

Compares well with the ESO VLT shot. All the little flocculent patches match!

Lovely. I wasn't aware of this one - yellow reflection nebulosity certainly provides something different to the usual reds, blues and cyans. Only one I'd seen before was the obvious Rho Oph.

Great to hear Tim, always nice to be able to share something fresh :thumbsup:



Yeah, everytime I ahve seen a shot of it I have thought, I must image that!....:)



Cheers Rick, the outer orb weaver legs are quite faint.



Yes, not many examples to compare with out there but from what I could find I am very happy with my result on this, as always better seeing would have helped buuuut ain't that a broken record :rolleyes:



Cheers Troy, yes Yellow reflection nebs are indeed a little rarer than the more common blue but worth the effort :)

excellent as usual Mike!
don't usually see the faint extensions like that too - they've come up nicely :thumbsup:

Yeah I was happy with seeing those too :)

Thanks for coming up with a nice unusual object Mike. Works very well the way the illumination creates a golden glow across the image.

Very nice details and colors. :thumbsup: The only other shot of it I remember is Jo Cauchi's 16". He's imaged it a couple of time. It's a very cool target.

wonderful shot love the details. hey Scott Alder managed to get a shot of this back in 2008 so press here for some time travel (http://www.iceinspace.com.au/forum/showthread.php?t=29532&highlight=toby+jug)

Mum & Dad used to have a jug just like this one! It was very cool and I loved it, just like this shot! :)

That's also the deepest Toby Jug i've seen, is that interstellar dust I can see extending off the bottom of full frame pic?

Lovely image Mike! Imaging at higher resolution open up a plethora of objects out there! I knew the name of this object but always wander what was about, thanks for clarifying with your drawing example, now I can see the old jug with a spider on it too ;)

Cheers

Cheers Rodney, yes it is that amazing glow that I was hoping to show :thumbsup:



Thanks Geert :)



Thanks Marc, yes I think I have seen Joe's image.. :question:



Yes I recall Scott's work Dave, cheers.



I've been doing a few less imaged objects lately, guess it is only the natural course of things for someone who has been recording the heavens for 34 years now Al :)



Thanks Marcus



Cheers Scotty and yes there is lots of Milky Way dust in the frame but also under a high contrast stretch it is very clear that the main nebula actually has a huge faint outer halo (http://www.pbase.com/strongmanmike2002/image/162542492/original)



Thanks Marco, glad my Michelangelo quality art work and vivid imagination were helpful :painting: :P

Have never seen this before in a photograph. It's an excellent little nebula and beautifully presented.
Very nicely done Mike.

Excellent Mike!. Different. Diffraction spikes are a bit intrusive, small niggle, presentation is spot on.

strongmanmike
11-02-2016, 07:58 PM
I am surprised it took so long for me to finally image it but I guess I didn't have a good enough image scale to hit it with properly until late 2013 :question:



Cheers Fred glad you liked it :thumbsup: I guess the diff spikes are unavoidable due to the optical design of my scope (it ain't no refractor dude) and the brightness of the central star :)

with Fred on this apart from the diffraction spikes..interesting and unusual object, nicely done. I recognise that spider given its recently taken residence in the RC8..

Cheers Dave :thumbsup: I check inside my OTA for fine diffraction inducing webs every night with a bright torch...the little spiders are the worst, they can be rather clandestine at times :)

Nice little yug there Mike.

Yes those little spiders are the worst. I stopped taking the cooling plates off the Honders as it was too inviting for those floating in air on a thin streamer of web spiders.

Greg.

So, what is happening with that Honders of yours anyway...? :shrug: you just teasing us huh? Making us wait huh? ;)

Great image Mike!

HD 65750 or V341 Car really gives the Toby jug a unique colour, amazing resolution! for the seeing conditions.

Cheers,

Justin.

Cheers Justin, yes the golden hue is very attractive huh? Thank god for deconvolution is all I can say...one day it would be good to have a scope under sub arc sec seeing...just for a laugh...I can only imagine :question: :rolleyes:

Thank god for deconvolution is all I can say......eh...what was that??

otherwise that is another beautiful image - relaxing to look at and technically excellent.

Yes well... when done properly, arhem.....it is a very powerful tool :D



Well thank you squire, from one of the masters of excellence... I'll take that :thumbsup: :prey2:

been looking at this a bit more. It looks to me like there is a classic dual lobe PN buried in there - what do you think?. That possibility is raised in http://adsabs.harvard.edu/full/1973A%26A....23..241D. but your image is the best available at showing the outer lobes - in fact most analyses (and images) ignore the outer region entirely.

Not sure what the colour means - have you seen any other PNs with a gold colouring? The literature identifies this as a reflection nebula, so I guess there is a lot of dust around and that could modify the light that gets out from any PN structure. In any event, I think that your image shows a lobe structure of some sort, that is not so clear in other images.

Hi Ray

I think this is a special type of planetary nebula and perhaps not a typical one? Most sources refer to the "dust" around the star having been ejected from the star itself and the stars yellow-red light then "reflects" off this rather than the more typical blue nebula caused by Rayleigh "scattering" of blue light.

From ESO:
"The nebula was created by the star, which is losing part of its mass out into the surrounding space, forming a cloud of gas and dust as the material cools. The dust consists of elements such as carbon and simple, heat-resistant compounds such as titanium dioxide and calcium oxide (lime). In this case, detailed studies of the object in infrared light point to silicon dioxide (silica) being the most likely compound reflecting the star’s light.
IC 2220 is visible as the star’s light is reflected off the grains of dust"

i see what Ray means esp with the shape!
seeing its so unique could be worth more scrutiny .. as i said you captured some great extensions - we'll see i guess! :thumbsup:

Nice one Mike. I like the way you've tamed the central star--I've always had trouble with it.

strongmanmike
22-02-2016, 04:30 PM
Cheers Geoff :thumbsup: Have you imaged it yourself? I went looking on your AstroBin site but couldn't find it, did you do it in the dark old days of the little refractor straw :P

I should probably reprocess it. Sure I could do a better job now.

Ah right..how'd I miss that :question: :screwy:...your central star there looks ok to me and we came up with very similar colours :thumbsup:

Hello Mike,

What a beautiful photo!
I haven't been on IIS for a while. So good to see the quality of photos is better than ever.

Such an unusual object. A new one to me.
So sharp and I love the colour.

Ross.

Hello Michael,

really nice - there aren't many yellow reflection nebula, and I think this one is the most beautiful one.
