RE: [APML] Centuria 400 and Milky Way

Wei-Hao,

The stars are so tiny on this image that most of them disappear on my laptop
screen!  A trick the magazines do for reproducing such highly detailed
images is to knock them out of focus. (Egad!)  Great shot...

PS:  Send some clear skies our way, I haven't had a night for 2 months!

Chris

Hi,

http://www.ifa.hawaii.edu/~wang/misc/milkyway_centuria400.jpg

This is taken by Centuria 400 Professional (an older version).
Lens is Pentax 67 90mm/F2.8 at F4.  Exposure time is 45 minutes.
This is only the central part of the field.

I used to have the impression that Centuria 400 is better for prime-focus
but not as good for piggy-back.  This impression was further enhaced by
Chris' test in May.  However, I had to use it for piggy-back for some
reason.  The result turns out much better than I expected.  It shows very
good sensitivity and balance over all three colors.  The color is saturated
as well.  In the future, I will definitely use it for piggy-back more.

Cheers,

Wei-Hao
