Gum 41: What the chicken is running from

[Placidus (Mike and Trish)]

Gum 41, on the south-western outskirts of the Lambda Centauri nebula.

We see what might be the head and body of a huge cricket, complete with eyes and "shocking" mouth-parts. Or perhaps a rearing spice-worm, ready to devour.

We guess that this is a relatively young star-forming region on the grounds that it is extremely weak in OIII and SII. We here present H-alpha only.

5 x 1 hr subs. Aspen CG16M on 20" PlaneWave. Field about 36'arc across.

Original image here.

(Attached is a thumbnail showing the very sparse OIII. Yellow Ha 5hrs, Blue OIII 5hrs. We decided not to pursue that avenue further.)

Be mildly nervous! Be very mildly nervous!

Best,
Mike and Trish

Now Mikey tut tut, that is the tip of one of the chickens outstretched wings mate, stop trying to confuse us all

Lovely Ha nuanced image (love that word now Marcus ), cool to see this bit so close up, those tiny Enceladus Geyser like features in the middle of the circular wing tip are something not noticed in the wide versions of this area

Well if I saw that one eyed monster lurking then I would be very chicken as well. I actually think that the smattering of OIII provides a nice little bit of contrast in the image. It is certainly a fascinating and busy area of the sky. I don't think that we will run out of targets there for some time. Thanks for sharing MnT.

Very nice Mike. Love the detail you are getting out of your 20 inch monster and long exposures.

Greg.

Interesting capture!
Thanks,

M+T !

Cheers,

[Atmos (Colin)]

Really nice MnT! There is a lot of detail in the region and apparently next to no oxygen! I assume there was even less SII?

It's a fair cop. We'll come quietly.

We see what you mean about the feathery ice geysers. Thanks for pointing that out.

Thanks, Rodney. Glad you think the OIII adds something.

Cheers, Greg. The whole area around lambda has proven quite interesting at 3.45 metres.

Thanks, Tim. Glad you like it too. It's getting a bit late in the season for all-nighters now, but next autumn we'll come back to the Lambda Centauri region for sure.

Best,
M & T

Top shelf data! OIII is certainly sparse, but what about SII?

Thanks, Suavi. A google search for keywords Gum 41 and SII got this very post, and an image of a pair of rubber thongs. We might try a 3x3 binned test shot.

Who knows, this may be history in the making

Well if this is the only mention Google could find, might be time for a 50 hour 2x2 bin onslaught in SII

Excellent shot of the Chicken McNugget, M&T

Great close up Mike. The Ha is quite a treat.

Thanks, Marc. We are tickled that you think so. Adding the other NB channels will almost certainly require binning as well as long integration time, but will probably be worth the effort. Those "mouth parts" look most intriguing.

[Placidus (Mike and Trish)]

Tonight we did the 15 min 3x3 binned SII test shot, and were rather surprised. Looks straightforward, even under the full moon. (Munch munch munch - sound of astronomer's hat being eaten). So we're rattling off 6 hours of 1x1 tonight.

[Atmos (Colin)]

And no teaser image... What is this?

[Ross G]

Great looking closeup Mike and Trish.

Love the detail and so sharp.

Ross.

[Peter Ward]

Probably running from 'd fish.

Not sure about the canary yellow rendition ...but like the monochrome version. Looks like kind seeing to boot

Cheers Peter! This H-alpha-only monochrome version is better for showing the faint outer details, which get lost in the colour version.

The HSO version is disappointing because it looks like a snap of a canary in a field of wattle and buttercups (Ha/SII), but it does show that there are very few bluebells or lupins (OIII) at that time of year.
