Ya shall not pass! :)
For this rework I tried to squeeze out as much of tha data as I could : 7h integration so a mere 2h20 per channel . The blue / yellow/orange palette suits this object so well in addition to stong structures in ha and s2. O3 is also strong for once. The surrounding area is full of ha making the background to process a headache . I opted for an approach I wanted to show the ha whereas you'll see many images with a dark neutral background. Unfortunately at the time of capture I still had the ZWO O3 filter that produces ugly halos around bright stars and adding salt to the injury my scope was the 80ED which behaves very poorly too on bright stars...

Hope you'll like it but this one was a real skill test for me (but it is IA free ;)=)

A littel bit of science : NGC 7380 (also known as the Wizard Nebula) is an open cluster discovered by Caroline Herschel in 1787. William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. It is also known as 142 in the 1959 Sharpless catalog (Sh2-142). This reasonably large nebula is located in Cepheus.

Located 7200 light years away, the Wizard nebula, surrounds developing open star cluster NGC 7380. Visually, the interplay of stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans about 100 light years, making it appear larger than the angular extent of the Moon. Although the nebula may last only a few million years, some of the stars being formed may outlive our Sun.
