NGC 1097 in Fornax


Scope: C8 f/5; Location: Blair Valley, Anza Borrego Desert, CA;  12  Nov. 2004; Camera: ToUcam SC3

Exposure: 16 x 90 sec Luminance exposure with IR Block Filter; 15 x 45 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.  Star sizes were reduced somewhat by a touch of a masked minimum filter in the Luminance channel. Luminance and Color FITS were combined in Photoshop with Luminance Layering.  Color balancing and final touches in Photoshop. SGBNR  (PixInsight LE) was used to smooth background noise on the luminance channel and the final result. Resized to approximately 720x540.

This image was a guided image. North is up in this image. This image could be better. Breezy conditions hampered stability, enlarged stars and caused lack of crispness in the galaxy structure. Perhaps this will be an opportunity for another try another season. The fuzzy object just above the galaxy structure is NGC1097A and its influence on the main galaxy structure is barely noticeable just below NGC1097A.  Horizontal FOV is about 16'
