NGC 288 in Sculptor


Scope: C8 at  f/5 Location: Dos Picos Park, Ramona, CA;   6  Nov. 2004; Camera: ToUcam SC3

Exposure: 20 x 7 sec and 24 x 24 sec exposures with IR filter 15 x 20 sec each RGB exposures.

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. The 24  sec  exposure was used as the base Luminance channel. The shorter Luminance exposure was normal combined with mask to control star size 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 800x600.

This image was guided. NGC 288 is a somewhat loose globular cluster.  The NGC 288 globular cluster is close to the more famous Sculptor Galaxy - many wide field images sow both the Sculptor Galaxy and the NGC 288 globular in the same image. The faint smudge near the bright star near the right edge of this image is a 15th magnitude galaxy PGC3068.  Horizontal FOV is 16'
