Here is another
quick test shot to determine feasibility of using the new Hutech
XTi with the SV80s for the primary instrument up at Happy Jack
at our Clear Creek Canyon Observatory. The focus is way off on
this shot, and I didn't get any core exposures to fill in the
center, however this shot does show that the blues and reds are
very effectively recorded with the camera. The noise level compared
to my old 10D is ridiculously low. In fact, no dark frames were
subtracted from this set.
Despite our brightening
skies in Payson, I am satisfied that this camera will be an excellent
addition to core instruments up at our second observatory, and
we will proceed with our plans to get a deep series of images
from that location at the next opportunity!
Processing note
A new trick I tried
here was to make a layer mask out of a negative of the image
itself to apply noise reduction to the sky and dim areas for
the most part.
