Wide Field west of the Large Magellan Cloud - N70 and lots of clusters (like NGC 2114 and 2098) and gas clouds

Revision title: New data

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.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
