N70: LMC Super Bubble

[CaptainCook (Gary)]

This is my first attempt at N70- the super bubble in the LMC. It is 300 light years across and has been created by multiple SNe that maintain a cavity of less dense hot gas with a cooler outer shell.

Its rarely imaged- just 26 photos of it exist on Astrobin- compared to the nearby Tarantula which is 100 times more popular (Orion has over 100,000 photos!) .

Details:
Askar 700mm with 533MM Pro, flats, bias, dark flats.
5 min subs, 6 hours of Ha plus 5 hours of O3. 6nm filters.
Bortle 7.
Processed as HOO with Foraxx palette for the stars.

The link to the image is here.

For context, it can also be seen as an unnamed object towards the top left of this mosaic I did last year.

Thanks mate, yes it was a lot of effort.

[AstroViking (Steve)]

Very well done.

For such an interesting object, there are surprisingly few images of it around.

When it gets a bit higher in the sky (towards mid-late December) I'll have another shot at it.

Cheers,
V.

That’s a cool target mate and some great detail revealed too. Well done

I wouldnt bank on there being any clear sky in December! Weathers only getting worse, in any case with NB theres no difference between 30 deg & 54 deg.

In my case there is a bottlebrush and house that disagrees with you

Nice I wasn't aware of that little beauty

[CaptainCook (Gary)]

Thanks Trevor. Hope to add more to it sometime...

Thanks for posting this interesting object Gary. Slightly off the beaten track for oft imaged targets.

A cool object, very corpuscular

Well done

Thanks...the plan was to add much more data but once again the weather has thwarted me. It would take me several years at this rate so I'll move on no doubt and end up doing Carina for 30 mins as usual.
