Scope: Celestron 9.25 Edge 235 mm at f/7, Location: Laguna Mountains, CA   18 April 2015  Camera: ST8300M

Exposure: Exposure: 16 x 8 min  (2x2 bin) exposure;  8 x 4 min (3x3 bin) RGB exposures.

Processing: Data Collection -  Sequence Generator Pro (as FITs).  Calibrated, stacked (Sigma Kappa Combine) in Deep Sky Stacker, L - RGB channel registration, equalization, central gradient removal - Astroart.  Curves, Levels, and Luminance development, RGB combine - Images Plus. Finishing  - Photoshop. Color calibration with eXcalibrator. This image is UV/IR Block for the Luminance channel and then a LRGB combine with Luminance layering.  Saturation in LAB color.   Final Image size processed at approximately 3352x2532 cropped and resized to 2000x1500.

North is up in this image.  This field  is dominated by the galaxy M98 also known as NGC 4192. Just below and to the left of M98 is a cluster of small distant galaxy. This galaxy cluster s known as Abell 1499. It is fairly distant from Earth at a little more than 2 billion light years (as estimated by red shift). Other notable galaxies in the field are the spirals NGC 4186 (foreground in the Abell 1499 galaxy cluster) and NGC 4192A (to the lower right of M98). These smaller galaxies and other background galaxies as well as M98  are identified  and highlighted in the annotated image.  M98 is estimated at 44 million light years distant from Earth.  The Horizontal FOV is 38'

Image center is approximately - Equatorial 2000: RA: 12h 13m 48.2s Dec: +14°53'43"
