Hi,
This is a comparison animation showing my mono result from
May 26 2009 compared to a RCOS 12.5" image with SBIG AO-7.
I found the RCOS image on a similar comparison animation on
the ATS scope supplies page here...about halfway down:
http://www.atscope.com.au/rcos.html
Now firstly, this is in
no way a definitive or laboratory comparison!.
Just a bit of fun.
Firstly, the RCOS image has been changed to a grayscale to match
my DSI II shot.
I have not altered anything on the RCOS shot apart from grayscale
and crop to match the animation.
My shot has been taken from the original
here.
Mine has been resized
down, and rotated 7 degrees to match the RCOS
shot.
So, if anything, mine has had some considerable loss of quality added.
I have done a histogram tweak on my image to suit the general size
of the RCOS halo.
Finally also, my shot is made of 365 frames x 5 sec with a Chinese
GSO-12" F5 and a mono DSI II chip (ICX 429).
I'm not sure what exposure was needed for the RCOS/ SBIG shot.
Comments/criticism welcome.
