Vela Nebula and new planetary nebula DeGaPe1

[APO_Team]

Hello everyone !

It's been a long time since our last message... Time is passing by so fast: shooting, processing, shooting again... and sleeping sometimes

Here we are with the Vela Nebula, this huge supernova remanent. This is so big that it will take a long time to complet the whole stuff ! We have about 2 degrees field.

This has been made in remote from Atacama, Chile, in the Alain Maury's SPACE. We have installed our observatory there last autumn and we enjoy the place at least 15 nights every month ! No time to cool down

We show you today a (HO)HOO version of the nebula and a B&W OIII version.
Why do we show you the OIII ? you will ask... Because we have found something on it: a planetary nebula !

We are very proud of it; this is our first discovery
It has been confirmed by the astrophysicist Agnès Acker from the Strasbourg university (Alsace, France). She gave it its name, maid with the beginnings of our three names: DeGaPe1 (Galli, Demange, Petit)
And this is quite funny because we all three (Thierry, Richard and I) are from this region. So, it was like a local story

Ok, enough speech for today...
Hope you will enjoy the picture !!

By the way, here is a challenge: do you think you can find it ??
I will add a closer picture soon...

PS: I have forgotten thumbnail... How can I add it ?? Didn't find

[Atmos (Colin)]

That looks amazing!
I'll have to have a search for that new discovery when I am not at work on my phone :-)

[Regulus (Trevor)]

Thanks for sharing those, and setting a challenge we'll all enjoy.
Very happy for you all on the discovery, and the fortunate name of the new planetary nebula.
They are supurb images.

Stunningly detailed and congrats on your discovery.

I've had a good look around the image but cannot really spot the planetary. I am quite interested as I did a very deep image in the same area in the last 9 months and would be pleased if I captured it in the same field.

[rustigsmed (Russell)]

Congratulations team!

That must be an exciting feeling

Not having imaged the area at all i'll guess to the left of the arrow, spherical looking spot?

Russ

[gregbradley]

Yeah that's the spot I saw as well. There is also a ring spot on one of the brightest O111 filaments.

I guess this is just part of the veil structure - but it looks like a complete oval like a faint PN? Maybe a bubble type structure?

[APO_Team]

Thank you guys !

Russ, that's exactly the spot !! Congrats
We where lucky to have it on the picture; it was almost out...

Tony, nice try ! This is not our nebula but the thing looks interesting. I think it's part of the whole remanent, has you said...

I would like to add a picture but can't find how to do it...
Where is the thumbnail option in the reply area ??
How did you do it Tony ?

See you later...
Tom

[Paul Haese]

Definitely out of the field of my image.

When you go reply, look down below the typing box and you will see manage attachments. You will get a pop up that lets you load images.

[APO_Team]

Thanks Paul ! I found it

It's a shame it is out of your field. It could have been interesting to see it.
We are waiting for some spectro on it... Don't know when it will come; next year maybe

Well I guess it is a lot easier when you know there is one in the frame - not so easy when you don't know ... how many catalogues do you have to check?

It jumped out quite clearly on the Oiii pic, perhaps its a practice people should take after they've spent some deep exposure time on an image ... to see if they've inadvertently made a discovery

[marco (Marco Lorenzi)]

Congrats on the image and on the discovery I am incidentally processing a mosaic of the same area, with frames I collected in 2014 (yeah, I know, I have a huge backlog to work out ) and indeed the little planetary splotch is right there, but I would never noticed it without your post..

Nice to know you all from Alsace, I go there time to time (my company HQ is located near Strasbourg) and always enjoy a nice Tarte Flambee or fried Munster with a good glass (or two ) or cold Riesling..

Cheers
Marco

[APO_Team]

rustigsmed -> actually yes, it's easier We checked about 4 or 5 catalogues and didn't find anything... This was quite good news ! Then we sent everything to Agnes Acker and she checked her catalogues and didn't find anything neither
You're right, that's something everyone should do... checking deeply to see if there is not something unusual... Sometimes it can pay

marco -> thanks and good luck for the mosaic !
Next time you come to Alsace, send us an email... we'll have a glass (or two) of Riesling together

[astroron (Ron)]

I spotted it as well ,,the O111 really brings it out.
Well done on your discovery, and of course a fine image.
Cheers

[APO_Team]

Thanks astroron !
And thank you all...

See you soon for new pictures
