Re: My first live stacks.
Wow,
Now that IS interesting.
A great result!

Re: My first live stacks.
Thanks Brian!
Yes i can see its a little unclear, each frame was 80 secs long, and i took and stacked 60 frames. All at 200 gain and black point at 24.
To look at the sky was milky with only the brightest of the plough stars visible.

Re: Thank You
Hi Robin i have seen your recent talk on the net, And as an OLD CCD die hard, I found your talk absolutely fascinating. I am now very keen to try out your methods on my altair mono and colour cameras, and my old QHY10 CDD. Is there any chance you can provide a little written explanation to your thou...
