Welcome to qdigital-astro.com, Astrophotography by Dave Watson
Astrophotography is a challenging subject and images are difficult to capture due to the vast distances, low light levels, and the fact that these objects appear to be in constant motion because of the earth’s rotation. At times overcoming these difficulties in capturing these subjects can be very frustrating, however, they are beautiful and can be quite stunning and worth the effort. Through determination, climbing a very very steep learning curve, and modern technology the wonders of our universe and the night sky can be captured as never before, andamazing deep-sky images can be obtained of star clusters, galaxies and nebulae.
I have had images included in Astronomy Now magazine, and exhibited at the British Science Festival, Edinburgh Science Festival, Manchester Science Festival, The Times Cheltenham Science Festival, Derry Millennium Centre, and the Royal Albert Hall.
I started in astrophotography in 2011 and this website is devoted to examples of my images that have been taken with a CCD camera mounted on a telescope from my observatory in Galera, Andalucia, Spain. The observatory is located at N37° 44' 22" W02° 33' 09".
The Tulip Nebula, Sh2-101, is located in the constellation of Cygnus within a complex area of nebulosity , and within a couple of degrees southwest of NGC6888, the Crescent Nebula. This area is strong in Ha and SII emissions, and is located about 2,000 light years away from us. Sh2-101 lies inside the Orion spiral arm of our galaxy, as does our own solar system. The star believed to be fueling the emissions of the Tulip nebula is HDE 227018.
This image also shows the famous Cygnus X-1 system, which is the brightest source of X-rays. It is a binary system, consisting of HDE 226868, a large blue super giant, and a companion that is thought to be a Black hole, the more compact of the two objects in the system is thought to be between 20 and 35 solar masses.
For the best viewing of the images on this sites pages, your monitor should be calibrated. Alternately, adjust the brightness and contrast of your monitor so that all of the grayscale steps are visible in the bar below, each block should be seen as a distinct step in shade of gray from its neighbor. The calibration bar should not have a color tint, however, if you see color then adjust your monitor's color settings.
