I put the package in this picture, I wanted to see if by force of brute one could see for example the corolla of M57 ... No ... or so little, so weak, but for the rest I am quite happy!
From June 11th to July 17th, about ten or so I was able to capture M57 and according to the quality of seeing I increased or decreased my focal length or exposure.
My usual gear:
300mm F4 OO
In all I have 14h stacking:
-A: 43200x500ms = 6h (50% of the total at FD8)
-B: 14400x1s = 4h (30% at FD 8 and 4)
-C: 3000x5s = 4h + (50% to FD 4)
I was able to have stars of Mg 21, some details on IC1296 and also LEDA2813726 (bottom left of M57) and 2MASX J18530959 (and what?)
