Description

WIth my work, I never know when I will be able to image next.
But last week, I was luck and I had anotehr clear night after the one I had on NGC1491
I stayed on that one to see what would be the result with much more data :
RGB : 10x10x10 x1mn (unchanged)
Ha : 79x5mn (36 previously)
Oiii: 31x5mn (6 previously !!)
Sii: 24x5mn (12 previoulsy)

The Oiii helpoed a lot for the colour compositoin and I could further with twice more data on Ha

Hope, you'll like it
