What nebula is this?

[AstroViking (Steve)]

Hi all,

I was wandering around the sky in Stellarium and found the attached nebula. It's somewhere in Vela, as NGC2626 is above it and NGC2671 is to the right.

The bright star in the centre is I815 / HIP 42908A / HD 74804.

Also, is there any setting in Stellarium that will turn on all the names / catalogue codes of the nebulae and star clusters? It seems a bit light on for what's out there.

Thanks,
V

That’s Messier 20; the Trifid Nebula. Well a copy of it anyway
It’s just made itself to another part of the sky!

In all honesty, not sure.

GUM 15, or RCW32

Also, see attached for the settings to tick so you can get more names to display in Stellarium. Just check all the catalogues.

It's the Valentine Nebula.
It will be in opposition next Tuesday.
Your day will start off with a little surprise so be prepared.
You have a secret admirer that's scared to show their feelings.
Be open and receptive and the Universe will guide your decision.

The more I look at this nebula, the more I like it.
Could be a great LRGB target.

[AstroViking (Steve)]

Thanks all, and especially AdamJL for both the name and the Stellarium settings I needed to change!

I'm thinking it's my next target when I get a chance. (Hopefully tomorrow and/or Friday night.)

Cheers,
V

Where is the like button?

Hmmm.. Well, I have 2 hours of L-Enhance data and 1 hour of UV-IR Cut and I have to say that it's a dim target and needs more (much more) integration time.

I would post the image but I am not happy with it, so you'll just have to wait a bit longer...

Cheers,

Gee you tackle the dim ones
I had a look on Astrobin at folks images of Gum 15 and most are using a Mono camera with 3nm narrowband filters capturing 20 to 35 hours of data to expose some decent detail
Good luck with this project

My own fault - I select a target by "Oh, that looks good!" without really checking how bright it is or how long the other images took to collect enough data.

I can see a few more nights collecting photons ahead of me...

[AdamJL]

Yep, I'd be aiming for 10 hours on this one, minimum.
