IC5070 - The Pelican Nebula
IC 5070, also known as the Pelican Nebula, is located approximately 1,800 light years from Earth in the constellation Cygnus.
The data for this image was acquired on August 23rd - 28th, 2008 at the CCD Sky Observatory in Redlands, California, USA. The final image seen here represents the combination of 13 hours worth of exposure (20 x 20-minute Ha (3nm) exposures) taken with a Takahashi FSQ-106ED telescope and a QSI 532wsi camera cooled to -10° C.
The sub-exposures were processed using CCDStack and Photoshop CS. The images were calibrated, registered, normalized, STD sigma reject and combined in CCDStack. The two resulting image was then brought into Photoshop for final processing. Noel Carboni's Astronomy Tools for Photoshop were used for local contrast enhancement, and to provide the false color (red tint to the image). Some additional processing was also done in Photoshop to balance the color and contrast of the image.
