                                      Image Acquisition Information

                               Telescope:   16" RCOS Richey Chretien Telescope (ion milled at 6/9)

                               Camera:       SBIG STL-6303 M

                               Guiding:       SBIG AOL, Astrodon MOAG AOG (SBIG 237 with FLR)

                               Filters:        Astrodon L, Ha, SII, OIII

                               Mount:        Software Bisque Paramount ME

                               Acquisition Programs:   The Sky,CCDAutopliot III, CCD Soft.

                               Processing Programs: CCDStack, Maxim DL, Photoshop

                               Date: March 7, 2008 - April 1, 2009

                               Time: 18x20 min ( 6 hours) each for each of L, Ha, SII and OIII:

                               Total of 24 hours imaging time.

                               Processing: CCD Stack and PhotoShop CS/3

Image Infornmation: This is a NB image with a minimal blending of a luminance image in order to bring out some of the small secondary galaxies and the faint nebula to the right of the owl nebula. The image represents a total of 24 hours of data from 4 filters. The nebula was discovered in 1781, is believed to have formed about 6,000 years ago and is about 2000 light years from the earth. From a structural perspective it is felt to be complex and astronomers have not been able to explain its shape and contours.

Additional Comments: The Narrow Band image was processed using CCDStack, producing a Narrow Band image (Hubble Palatte). The Narrow Band image was created by equally weighting the SII, Ha and OIII images and assembling in CCDStack. The Luminance data was produced in CCDStack which was lightly blended into the NB image using layers (normal mode) in Photoshop CS/3, bringing out the faint emission nebula and small secondary galaxies. The Further data stretching, high pass filtering and background smoothing was performed with Adobe Photoshop CS/3.
