M6 and NGC6416 in Scorpius
|
Scope: ST80 f/2.5, Location: Del Mar, CA; 5 Aug. 2004, Camera: ToUcam SC3 Exposure: 20 x 4 Luminance with IR block filter and 16 x 12 sec with IR block and Orion Skyglo filter, 16 x 5,5,6 sec each RGB filter. 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 IR and Skyglo Luminance exposure were combined to maximize depth and control star size. 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. Image was resized to 800 x 600. This image was an unguided image. This image is a wide field image of Southern Open Clusters. M6 is sometimes called the Butterfly Cluster Cluster - it can be seen to the right side of the image. NGC6416 is the larger, looser cluster on the left. North is up. A close in image of M6 is shown Below. Horizontal FOV is about 80'
Scope: ST80 f/5, Location: Del Mar CA; 5 Aug. 2004 , Camera: ToUcam SC3 Exposure: 18 x 7 sec Luminance with IR block filter and 15 x 20 sec and 16 x 7 sec with IR block and Orion Skyglo filter, 18 x 5,5,6 sec each RGB filter. 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. The 5 sec IR , 20 sec Skyglo, and 7 sec Skyglo exposures were combined for optimum star appearance. Channels were co-registered in Astroart. Luminance and Color FITS were combined in Photoshop with Luminance Layering. Color balancing and final touches in Photoshop. Image was resized to 800 x 600. This image was an unguided image. The overall field is about half of the above image. Horizontal FOV is about 40'
