AP7 Tri-Color Image

The black & white image is a composite of 15 one-minute exposures combined by median addition.

 

The color image is a combination of five 60-second Red (R), five 60-second Green (V), ten 60-second Blue (B), and ten 60-second black white images. The black and white images were median combined to make a Luminance (L) image. These color filter and Luminance images were combined into a final color image.

AP7 Tri-Color Image

 

 

 

 

 

 

The AP7 tri-color image consists of three 60-second black & white images combined to form a luminance image used with three 60-second Red (R), three 60-second Green (V), and five 60-second Blue (B) images to make a final color image.

NGC6992 Eastern Veil Nebula; Caldwell 33 NGC6992  
NGC7000 North American Nebula; Caldwell 20 ngc7000 North American Nebula This image only shows part of the North American Nebula due to the relatively small size of the Starlight Xpress SXVR-H9C CCD camera giving an area of approximately 50 x 40 arcminutes. The present image is a mosaic of three images, each of which was composed from approximately twenty-eight 60-second exposures median combined.

NGC7331

C-11 Hyper Star image with Starlight Xpress SXVR-H9C camera

 

The KX260 image is a composite of 8 one-minute exposures combined by median addition.

 

 

The AP7 image is a composite of ten one-minute exposures combined by median addition.

 

The AP7 color image consists of three 60-second black & white images through a clear filter combined to form a luminance image used with one 60-second Red (R), one 60-second Green (V), and two 60-second Blue (B) images to make a final color image.
