Description

Objects to the west of the Large Magellan Cloud. At the first sight you see a number of open cluster, and in the left hand side border, near the centre of the border, a globular cluster, ESO 57-43. At the top left corner the star e-Dor,  and at the very centre, the N70 super bubble cloud. Sometimes also designed as LH120-N70, which is a supernova remnant, and has 300 ly diameter. Below it you have two clusters NGC 2114 and NGC 2098.
There is an article here on its early characterization: http://astroimg.org/articles/LH120N70-MarchApril1994.pdf
I did crop the large image an annotated as image B.
There is a problem in my images, I did not try star reduction, so a lot of halos are around the stars and, it seems the effect has to do with a faster optics. I hope is not the UV/IR Cut filter, anyway... I have to learn how to reduce halos.

For the colours I did photometric colour calibration, selecting one of the star clusters as main coordinates. From there, I had to reduce a bit the bluish, it has strong blue colours on the structure above N70.

Title: New data

Description: The problem was my focuser, so the star halos were just due to out of focus. I run a few test to finally discover that the focuser was not doing the proper job (my fault anyway).
So last night I repeated for a 6 hr exposure (180x120" images) and now is much better.
