This is the same image shown here:

...but with a more aggressive stretch.
During processing my Messier 1-image in a normal way (
https://www.astrobin.com/7pgs7l/) already in the early stages I was surprised to see a lot of rather faint but clearly detectable nebulosity around the object of desire. A simple STF-stretch already did reveal that a lot of other things are going on around Messier 1.
Of course these faint nebulas are not related to Messier 1. Instead, they should be related to the Taurus Molecular cloud (most prominent around Messier 45 several degrees away) or another kind of IFN (galactic cirrus).
Personally, I think that there are two interesting aspects of this picture showing the faint nebulae around the prominent SNR itself. These two aspects I would like to highlight, they mainly motivated me to show this second version of my Messier 1-image.
At first, there are hundrets of Messier 1 pictures floating around here on Astrobin. Only a handful (mostly widefield images) show at least the brighter parts of this IFN.
The second aspect is that this picture was acquired by using only 10sec exposure length! Thanks to modern Cameras with low read-noise together with a fast focal ratio already a moderate total exposure time of only 5,4hrs, summed up by 1951x10sec subs, turned out to be sufficient to clearly show these fairly faint structures.
