This single ten minute exposure
from our extremely dark and transparent skies at the observatory
in Happy Jack (Clear Creek Canyon Observatory) shows a level
of sharpness and detail seen only with or former schmidt cameras
and tech pan film and an hour long exposure. This is the central
star in the constellation of Cygnus, and the entire field is
filled with glowing hydrogen nebulosity. In fact, the only dark
sky background seen here is in the two dark nebula on the left
To show the
extreme sharpness of the SV80s with the TV.8x FF/Reducer, I enlarged
two of the star clusters that are at the very top of the frame.
Look at those star images! They are round, crisp and very sharp.
Both clusters are in a sea of hydrogen nebulosity - thats why
the background is so bright in each image. Can you just imagine
the color image you can take of these two clusters sitting in
an ocean of gorgeous pink nebulosity?
