M97 - Owl Nebula in Ursa Major


Scope: C8 f/5; Location: Culp Valley Anza Borrego Desert, CA; 13 Mar. 2004; Camera: ToUcam SC3

Exposure: 12 x 90 sec Luminance exposures with Baader IR Block Filter; 12 x 60 sec RGB 

Processing: Images were captured in K3CCDTools. Aligned/stacked in Registax and saved as FITS. Luminance and Color channels were scaled and rough color balanced in Astroart. Channels were co-registered in Astroart. Luminance and Color FITS were combined in Photoshop with Luminance Layering. Color balancing and final touches in Photoshop. SGBNR was used to smooth background noise on the luminance channel and the final result.

This image was taken with fairly good conditions at a dark site. This is a guided image. This is the so called Owl Nebula. The color seems a little more blue than I would expect, but the hint of red in the outer wisps was expected. Two other non-stellar objects can be seen in the image - one is PGC34279 in the lower part of the image. The other is unidentified in the upper portion of the image, but it does appear in Digital Sky Survey images. Horizontal FOV is 16'
