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

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