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 side!

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?
