hi,
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
ASI224Mc
Atlas (eq6)

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?)

That's quite amazing! Would you mind sharing the details of your processing? I had a go on M57 myself. Just about 100 frames of 5 seconds. It seems I just can't get any color out of it. I recorded FITS images as 8 bit raw with SharpCap. I tried Deep Sky Stacker (which I used a lot before with my DSLR and CCD) but it won't recognize the color. I select the FITS option and still the images are listed as 8 bit greyscale...

Any help would be greatly appreciated!
