Re: [APML] Astronomy Magazine M8

Thanks Dean,

Does Nigel indicate what is responsible for the very blue look of his shot?
What type of detector and filters were used?  I agree that the Astronomy
version is very close, my only comment is that they seem to have used a low
res version and expanded it, resulting in star sizes larger than the
original shot.

Thanks for finding the link, great image..........

Jim
