NGC 891 in Andromeda


Scope: C8 f/4; Location: Dos Picos Park, Ramona, CA;  6  Nov. 2004; Camera: ToUcam SC3

Exposure: 16 x 50 sec Luminance exposure with IR Block Filter; 13 x 40 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 combining a less curved/stretched  image of the 50 sec Luminance exposure with the normally processed version. 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 800x600.

This image was a guided image. North is to the Right in this image. This object is a commonly imaged edge on Galaxy; it is probably the second most well known Galaxy other than the Andromeda Galaxy in this namesake constellation.  Horizontal FOV is about 16'
