NGC 457 - Owl Cluster in Cassiopeia


Scope: C8 f/3.3 Location: Del Mar CA 9/16/2003 and 9/17/2003 Camera: ToUcam SC3

Exposure: 12 x 12 sec, 18 x 2 sec Luminance Exposure with IR Block. 18 x 4 sec RGB Exposures.

Processing: Images were captured and aligned in K3CCDTools and saved as FITS. Luminance and Color master frames were coregistered in Astroart with some low pass filtering. Luminance and Color FITS were combined in Photoshop with some Luminance Layering. Star bloating was reduced with the 2 sec Luminance exposure. Final touches in Photoshop.

I did a quick B&W exposure on the 16th and liked it so well I added color exposures taken the next day. Horizontal FOV is 23'
