Prints To Make A Pool Table

The sky at 8.3 megapixels

Tonight I took my new camera QHY9, equipped with CCD sensor KAF-8300 Kodak, 13x18mm and 5.4x5.4 micron pixel. The focus of my reflector telescope of 203 mm and 1600 mm focal length offers a field of 20x39 arcmin, really generous and very comfortable to work.

Ritchey-Chretien optics seems to give good results, judging by the first light the camera we see below.

some stars are achieved fairly thin and round around the field, including borders, and all at a hastily-made approach; the definition we have allows us to capture a variety of nuances in the cluster M13. No decision has been applied or dark (dark) or flat, noise pixels can be seen loose in the upper left corner, but it is generally enough to achieve lower easily achieved a temperature of -25 º C.

Camera being good, but there are still things to resolve with the software, primarily for the wheel holder.
